`
`00:14:34  15                    MR. WANG:  Before ‐‐ sorry.  I
`
`          16             didn't realize we weren't making
`
`          17             appearances.  This is Don Wang.  I'm here
`
`          18             from Axinn, Veltrop & Harkrider.  We are

`DrStanleyShanfield_Rough
`
`          19             here on behalf of the Ocean Semiconductor
`
`00:14:43  20             LLC, and also here with me is Ed Krause.
`
`          21             We just want to make an objection on the
`
`          22             record that Mr. Zito has not appeared in
`
`          23             the two matters before ‐‐ before what
`
`          24             we're doing today which is IPR2021‐01342
`
                                                                           5
`
`00:15:03   1             and IPR‐01344.  My understanding is the
`
`           2             Mr. Zito will file an appearance by the
`
`           3             end to the day.  Thank you.  Sorry for the
`
`           4             interpretation.
`
`00:15:15   5                    MR. ZITO:  No problem.  That's our
`
`           6             understanding today, too.  I will file my
`
`           7             appearance by the end of the day.
`
`           8   BY MR. ZITO:
`
`           9        Q.   Good morning, again, Dr. Shanfield.
`
`00:15:24  10        A.   Yes.
`
`          11        Q.   Good to see you.
`
`          12        A.   Likewise.
`
`          13        Q.   You understand we're here on two patents
`
`          14   today?
`
`00:15:33  15        A.   Yes.
`
`          16        Q.   Okay.  The 248 and the 305 patent,
`
`Page 5
`
`

`

`          17   correct?
`
`DrStanleyShanfield_Rough
`
`          18        A.   Correct, yes.
`
`          19        Q.   All right.  And my understanding we're
`
`00:15:44  20   doing this as a combined deposition where I'm going
`
`          21   to you questions in this one deposition can be used
`
`          22   in both of those IPRs.
`
`          23                    MR. ZITO:  Is that also Counsel's
`
`          24             understanding?
`
                                                                           6
`
`00:15:59   1                    MR. WANG:  That's fine with us.
`
`           2                    MR. ZITO:  We're not going to split
`
`           3             it up into one patent versus the other,
`
`           4             okay.
`
`00:16:04   5   BY MR. ZITO:
`
`           6        Q.   Looking at the ‐‐ let's look first at the
`
`           7   6,968.248 patent.  Can you briefly summarize what
`
`           8   your understanding is of the teacher teachings of
`
`           9   the 248 patent?
`
`00:16:20  10        A.   I think the abstract is a good
`
`          11   description.  It a method and apparatus for
`
`          12   scheduling in an automated manufacturing
`
`          13   environment.
`
`          14        Q.   And would that be the same description for
`
`00:16:40  15   the 305 patent?
`
`Page 6
`
`

`

`DrStanleyShanfield_Rough
`
`          16        A.   Yes.
`
`          17        Q.   And can you tell me what in the timeframe
`
`          18   of the filing or the priority date of 2002 what was
`
`          19   met by scheduling in a manufacturing environment?
`
`00:17:06  20                    MR. WANG:  Objection, scope and
`
`          21             form.
`
`          22   BY MR. ZITO:
`
`          23        Q.   From a perspective of one of ordinary
`
`          24   skill in the art?
`
                                                                           7
`
`00:18:28   1        A.   So I take this question up to some extent
`
`           2   in my declaration paragraph 131 where the preamble
`
`           3   says a method for scheduling in an automated
`
`           4   manufacturing environment and as I explained there,
`
`00:18:51   5   Schulze discloses such a manufacturing environment.
`
`           6   He's describing a semiconductor fabrication facility
`
`           7   within an automated monitoring an assessment system.
`
`           8   So that would be my understanding of one version of
`
`           9   an automated manufacturing environment.
`
`00:19:18  10        Q.   Scrolling ‐‐ I'm scrolling down to
`
`          11   paragraph 101.  Give me a second.
`
`          12        A.   101 in where?
`
`          13        Q.   Right.  In your declaration?
`
`Page 7
`
`

`

`DrStanleyShanfield_Rough
`          14        A.   Okay.
`
`00:19:32  15        Q.   Okay.  Where you talk about Gupta
`
`          16   teachings, is that the paragraph you're looking at?
`
`          17        A.   No.  No.  131.
`
`          18        Q.   131.  My mistake.  All right.  So you use
`
`          19   Schulze as the reference ‐‐ that's Schulze 083,
`
`00:20:08  20   which is the Schulze patent application publication,
`
`          21   correct, that you're referring to?
`
`          22        A.   Yes, that's correct, Exhibit‐1007.
`
`          23        Q.   And you use that for as an example of your
`
`          24   understanding of person of ordinary skill in the art
`
                                                                           8
`
`00:20:28   1   for an automated manufacturer environment in the
`
`           2   2002 timeframe?
`
`           3        A.   That's correct.
`
`           4        Q.   You go on to say that a person of ordinary
`
`00:20:56   5   skill in the art would be automated to combine the
`
`           6   teachings of Schulze and Gupta.  What does Gupta add
`
`           7   to Schulze?
`
`           8        A.   What Gupta and Schulze combined it
`
`           9   discloses a photo for scheduling the operation of
`
`00:21:17  10   interrelated machines which perform on process flow
`
`          11   on a highly automated in this case front end
`
`          12   manufacturing facility for integrated circumstances
`Page 8
`
`

`

`DrStanleyShanfield_Rough
`
`          13   and that comes from circuits and that comes from
`
`          14   Gupta's abstract.
`
`00:21:43  15        Q.   Okay.  And that would make ‐‐ combining
`
`          16   these two would make a system for automatic
`
`          17   scheduling or just Gupta has the system for
`
`          18   automated scheduling?
`
`          19                    MR. WANG:  Objection.  Form.
`
`00:22:00  20                    THE WITNESS:  So, what I am saying
`
`          21             is that a person of skill in the art would
`
`          22             have in motivated to combine Schulze and
`
`          23             Gupta in that combination discloses a
`
`          24             method for scheduling the operation of
`
                                                                           9
`
`00:22:20   1             interrelated machines, which perform a
`
`           2             process flow in a highly automated front
`
`           3             end manufacturing facility for integrated
`
`           4             circuits.
`
`00:22:32   5   BY MR. ZITO:
`
`           6        Q.   But neither of them alone keeps that; is
`
`           7   that correct?
`
`           8        A.   No.  I don't know which ‐‐ what part of it
`
`           9   you're referring to but ‐‐
`
`00:22:44  10        Q.   Okay.
`
`Page 9
`
`

`

`DrStanleyShanfield_Rough
`          11        A.   I don't agree with that statement.
`
`          12        Q.   Well then why come ‐‐ if either Gupta or
`
`          13   Schulze alone taught a method for scheduling in an
`
`          14   automated manufacturing environment what would be
`
`00:23:00  15   the need to combine them?
`
`          16                    MR. WANG:  Objection to form.
`
`          17                    THE WITNESS:  You had started off
`
`          18             by asking me what an automated
`
`          19             manufacturing was and ‐‐
`
`00:23:25  20   BY MR. ZITO:
`
`          21        Q.   Right.
`
`          22        A.   And I said that Schulze disclosed that.
`
`          23        Q.   Correct.  But in shelters there isn't any
`
`          24   scheduling of anything in that environment, correct?
`
                                                                          10
`
`00:23:39   1                    MR. WANG:  Objection, form.
`
`           2                    THE WITNESS:  No, it's not correct.
`
`           3   BY MR. ZITO:
`
`           4        Q.   Okay where does Schulze talk about
`
`00:23:44   5   scheduling things in an automated manufacturing
`
`           6   environment?
`
`           7        A.   So Schulze uses or describes a system and
`
`           8   method for automated monitoring assessment of a
`
`           9   fabrication facility.  One of the aspects that you
`Page 10
`
`

`

`DrStanleyShanfield_Rough
`
`00:24:53  10   read about in Schulze in paragraph 15 at the bottom
`
`          11   is what he says during operation, the state models
`
`          12   are updated for each tool affected by one of the
`
`          13   triggers and transitions within the state model are
`
`          14   recorded in a track tracking database.  So there
`
`00:25:21  15   they're state of equipment whether ‐‐ and I think he
`
`          16   gives a number of examples, unscheduled downtime,
`
`          17   that's in Paragraph 8 in about the middle, scheduled
`
`          18   downtime, engineering time, stand by time,
`
`          19   productive time, all of those are inputs to a
`
`00:25:46  20   scheduling activity and so Schulze is ‐‐ relates,
`
`          21   you know, intimately with what is required to
`
`          22   perform scheduling and provides that information to
`
`          23   be able to accomplish scheduling Schulze.
`
`          24        Q.   Is there any place else that you believe
`
                                                                          11
`
`00:26:28   1   Schulze discusses scheduling?
`
`           2        A.   That ‐‐ those aspects of states is
`
`           3   discussed all the way through Schulze.  It would
`
`           4   probably take me 20 minutes to go through all the
`
`00:26:49   5   places where this equipment state concept is
`
`           6   discussed, so your question would take a while to
`
`           7   answer.
`
`Page 11
`
`

`

`DrStanleyShanfield_Rough
`           8        Q.   All right.  And does Schulze talk about
`
`           9   changing scheduling based upon it's monitoring of
`
`00:27:09  10   any of these state models?
`
`          11        A.   Could you repeat your question.
`
`          12        Q.   Sure.  Does Schulze has as you said for
`
`          13   monitoring equipment, correct?
`
`          14        A.   No, I didn't say that.
`
`00:28:24  15        Q.   Okay.  Then you read from about missing
`
`          16   semiconductor fabrication facility?
`
`          17        A.   Right.
`
`          18        Q.   And does that through not directly
`
`          19   monitoring the single time equipment but
`
`00:28:41  20   receiving ‐‐ Mary ‐‐ state signals amongst other
`
`          21   things regarding each piece of equipment; is that
`
`          22   correct?
`
`          23        A.   That's one aspect, yes.
`
`          24        Q.   Does Schulze provide any of the
`
                                                                          12
`
`00:29:08   1   information it receives or monitoring to a scheduler
`
`           2   does it talk about that anywhere?
`
`           3                    MR. WANG:  Objection.  Form.
`
`           4                    THE WITNESS:  Well, let me direct
`
`00:29:24   5             you to paragraph 17 about the middle of
`
`           6             the paragraph where it talks about a state
`Page 12
`
`

`

`DrStanleyShanfield_Rough
`
`           7             model logic receives the tracking
`
`           8             operation information for each fabrication
`
`           9             tool having define states in a state
`
`00:29:45  10             transition logic defining triggering
`
`          11             events and a state transitions related to
`
`          12             the trigger ‐‐ the triggering of that ‐‐
`
`          13             of events.  Schulze also talks about
`
`          14             triggering events and essentially that
`
`00:30:03  15             change of state is the input a scheduler
`
`          16             is going to take, is going to need and
`
`          17             therefore it's more than just passive
`
`          18             information.  There is triggering events
`

`
`          22   BY MR. ZITO:
`
`          23        Q.   So a state change transition logger is
`
`          24   part of the Schulze system?

`00:31:20   1                    MR. WANG:  Objection, form.
`
`           2                    THE WITNESS:  I didn't say anything
`
`           3             about a logger.  I said that Schulze
`
`           4             establishes the state model logic from the
`
`Page 13
`
`

`

`DrStanleyShanfield_Rough
`00:31:35   5             tracking operation information and at and
`
`           6             that some of this logic results in
`
`           7             triggering events.  Triggering events will
`
`           8             end up being and are required for
`
`           9             scheduling material in the ‐‐ in the
`
`00:31:54  10             semiconductor scheduling waivers within
`
`          11             semiconductor facility.  So it very
`
`          12             directly and intimately involved with
`
`          13             the ‐‐ how the scheduling changes and how
`
`          14             it evolves in the fab.
`
`00:32:23  15   BY MR. ZITO:
`
`          16        Q.   Does Schulze state that, what you just
`
`          17   said that these triggering events are important for
`
`          18   scheduling?
`
`          19                    MR. WANG:  Objection to form.
`
`00:34:15  20                    THE WITNESS:  Maybe I'm not explain
`
`          21             myself well enough.  Let me give you an
`
`          22             example.  Paragraph 75 in Schulze talking
`
`          23             about a particular state transition and he
`
`          24             describes that as defined as an automatic
`
                                                                          14
`
`00:34:39   1             transition from a productive state to an
`
`           2             unscheduled down state.  So it's apparent
`
`           3             in that state transition how relevant
`Page 14
`
`

`

`DrStanleyShanfield_Rough
`
`           4             it ‐‐ apparent to a part to scheduling, I
`
`00:35:00   5             think.  Reading, you know, or in
`
`           6             understanding that I and this would be a
`
`           7             person of any skill in the art really will
`
`           8             understand that going from productive
`
`           9             state to an unscheduled down date has to
`
`00:35:16  10             be part of the input to a scheduling
`
`          11             system.  I don't know that it could be
`
`          12             anymore clear than that.
`
`          13   BY MR. ZITO:
`
`          14        Q.   So am I correct that your testimony is
`
`00:35:28  15   that one or ordinary skill in the art recognize the
`
`          16   relevance of these states to scheduling?  It is not
`
`          17   that Schulze specifically says these states are
`
`          18   relevant to scheduling; is that correct?
`
`          19                    MR. WANG:  Objection, form,

`
`          22   BY MR. ZITO:
`
`          23        Q.   Okay.  Then where does Schulze
`
`          24   specifically directly state that understand where it
`
                                                                          15
`
`00:36:04   1   directly state that these ‐‐ that the states that
`
`Page 15
`
`

`

`DrStanleyShanfield_Rough
`           2   are monitored in paragraph 17 would be useful for or
`
`           3   directly relate to a scheduler?
`
`           4                    MR. WANG:  Objection to form.
`
`00:36:54   5                    THE WITNESS:  Well the example I
`
`           6             gave you is one place where Schulze refers
`
`           7             to unscheduled down state.  He's clearly
`
`           8             thinking about schedule versus unscheduled
`
`           9             downtime being irrelevant difference in
`
`00:37:18  10             it's state and it's only going to be
`
`          11             useful for scheduling.  So it's a you
`
`          12             know, a fact of the description that
`
`          13             Schulze is providing that scheduling is
`
`          14             intimately involved in or rather the
`
`00:37:43  15             states that Schulze is providing are
`
`          16             required during scheduling.  You know,
`
`          17             the ‐‐ I don't know that I can explain it
`
`          18             anymore thoroughly then that.
`
`          19   BY MR. ZITO:
`
`00:37:58  20        Q.   Right.  And what I'm not asking for ‐‐ I
`
`          21   understand your opinion on what Schulze is thinking.
`
`          22   And I ask your opinion of what you believe one
`
`          23   ordinary skilled in the art and I'm not asking you
`
`          24   for an explanation I'm asking you to where you can

`

`DrStanleyShanfield_Rough
`
`00:38:15   1   point to where Schulze specifically states where
`
`           2   Schulze was thinking that unscheduled downtime would
`
`           3   be important to scheduling where he specifically
`
`           4   makes that statement not what you are giving an
`
`00:38:29   5   opinion on his thinking?
`
`           6                    MR. WANG:  Objection, form.
`
`           7                    THE WITNESS:  Well, it may take me
`
`           8             a while to determine whether that
`
`           9             specifically said but I think it ‐‐ it's
`
`00:39:19  10             apparent, for example, in Paragraph 81
`
`          11             when a trigger message causes an automatic
`
`          12             transition from an unscheduled down state
`
`          13             to a productive state, there isn't
`
`          14             anything more relevant to a scheduler then
`
`00:39:39  15             when equipment is in a scheduled down
`
`          16             state and then makes the transition back
`
`          17             to a productive state.  That's obviously
`
`          18             something that would be required in order
`
`          19             to perform scheduling.  So once again,
`
`00:39:58  20             there's statements all over shut Schulze
`
`          21             about the nature of the system that he's
`
`          22             describing and the method and the mention
`
`          23             of scheduling and a sense of unscheduled
`
`          24             or scheduled downtime is in there as as

`
`           2   BY MR. ZITO:
`
`           3        Q.   And Schulze receives all of these

`

`
`          19   BY MR. ZITO:
`
`00:41:20  20        Q.   Let me take you back to paragraph 17.
`
`          21   Roughly where you left off.  It says ‐‐ roughly in
`
`          22   the middle of the paragraph and a state transition
`

`
`

`

`DrStanleyShanfield_Rough
`          23   logic defining triggering events and a state trans
`
`          24   later to the trigger event.  Is that logic part of
`
                                                                          18
`
`00:41:52   1   the Schulze system?
`
`           2        A.   I'm sorry.  Where were you reading in 17?
`
`           3        Q.   17 ‐‐ one, two, three, four, five, six,
`
`           4   seven, eight lines down at the end of that line the
`
`00:42:07   5   sentence starts with a state model logic.
`
`           6        A.   Okay.  A state model logic receives the
`
`           7   tracking operation information for each fabrication
`
`           8   tool having defined states and a state transition
`
`           9   log defining trigger events and the state
`
`00:42:33  10   transitions related to the triggering events.  So
`
`          11   he's describing there the state model logic of his
`
`          12   method, receives tracking operation information and
`
`          13   then determines a state and a state transition.
`
`          14        Q.   Okay.  So the tracking operation
`
`00:43:01  15   information could be in the two examples you picked
`
`          16   out productive or unscheduled downtime is that a

`
`00:43:14  20   BY MR. ZITO:
`
`          21        Q.   So what would be the tracking operation
`Page 19
`
`

`

`          22   information that's received?
`
`DrStanleyShanfield_Rough
`
`          23        A.   That would be what, for example, I mean,
`
`          24   and he shows us in his diagram, Figure 1, the MES,
`
                                                                          19
`
`00:43:33   1   manufacturing execution system provides tracking
`
`           2   operation information and then Schulze has another
`
`           3   box, let me go up to that diagram, Figure 1, calls
`
`           4   monitoring and assessment system and that ‐‐ that
`
`00:44:00   5   determines the state and has a high did of state
`
`           6   transitions designed in to it.
`
`           7        Q.   And that state transition logic would then
`
`           8   define it's triggering event as productive or
`
`           9   unscheduled downtime, for example?
`
`00:45:34  10        A.   Schulze actually goes into a lot of detail
`
`          11   in Paragraph 8 on that point.  He starts with a
`
`          12   description of this E ten standard, semi standard,
`
`          13   which defines six basic equipment states, total time
`
`          14   for each tools is divided into operations time and
`
`00:45:56  15   non scheduled time and then in about the middle the
`
`          16   paragraph operations time is divided into five
`
`          17   different categories, unscheduled downtime,
`
`          18   scheduled downtime, engineering time, stand by time,
`
`          19   productive time.  So those are examples of the
`
`Page 20
`
`

`

`DrStanleyShanfield_Rough
`00:46:13  20   states that ‐‐ in Schulze's method that are can be
`
`          21   assumed and then there are hierarchies of states.
`
`          22   So the ‐‐ he's following the semi standard
`
`          23   definition of the six basic equipment states.
`
`          24        Q.   So operations time is a state?
`
                                                                          20
`
`00:46:51   1        A.   No.  Total time for each tool is divided
`
`           2   into operations time and non scheduled time and then
`
`           3   operations time is divided into these categories of
`
`           4   states, unscheduled downtime, scheduled downtime,
`
`00:47:06   5   engineering time, stand by time and productive time.
`
`           6        Q.   All right.  So ‐‐ around or?
`
`           7        A.   And this comprises the six basic equipment
`
`           8   states.
`
`           9   BY MR. ZITO:
`
`00:47:16  10        Q.   So unscheduled downtime is a state?
`
`          11        A.   Yes.
`
`          12        Q.   Okay.  Good that's what I thought you said
`
`          13   in 75 and 81 and I was trying to relate that to
`
`          14   paragraph 17.  It says a state model logic receives
`
`00:47:30  15   a tracking operation for each fabrication tool
`
`          16   having defined states, okay.  So does ‐‐ is that
`
`          17   where ‐‐ where the model logic receives unscheduled
`
`          18   downtime state?
`
`Page 21
`
`

`

`DrStanleyShanfield_Rough
`
`          19        A.   No.  The box in Schulze's Figure 1
`
`00:47:53  20   receives tracking operation information from MES for
`
`          21   each fabrication tool.
`
`          22        Q.   Okay.
`
`          23        A.   And then that box defines trigger event,
`
`          24   state transitions related to the triggering event
`
                                                                          21
`
`00:48:12   1   and so on.
`
`           2        Q.   Okay.  Then the next sentence says if the
`
`           3   fabrication tool has a state change, that would be
`
`           4   like from unscheduled downtime to productive time
`
`00:48:25   5   would that be a state change?
`
`           6        A.   Yes.
`
`           7        Q.   Okay.  A state change transition logger
`
`           8   inputs this information to a tracking database
`
`           9   recording transition information.  So that's also
`
`00:48:43  10   part of the Schulze system?
`
`          11        A.   That's what he describes, yes.
`
`          12        Q.   Okay.  Then he describes a report
`
`          13   generator that may generate performance matrix for
`
`          14   the fabrication tools, that's also part of the
