`
`PATENT OWNER’S MOTION FOR
`OBSERVATIONS ON CROSS-EXAMINATION
`
`
`
`1 Case IPR2017-01842 has been consolidated with this proceeding. See Paper 10 at
`3.
`
`
`
`
`
`
`
`Godo Kaisha IP Bridge 1 (“Patent Owner”) submits this motion for
`
`observations regarding the cross-examination of Petitioner’s expert (“Shanfield”).
`
`I.
`SHANFIELD TESTIMONY REGARDING ACTIVE REGION
`Observation #1: In Ex. 2026 at 95:4-96:18, Shanfield admitted that his “proposed
`
`construction for the ’501 patent [is] that an active region made of a semiconductor
`
`substrate is an area of the semiconductor substrate defined by an isolation region
`
`where the transistor is formed”2 and at 88:10-89:7, 92:9-14 he admitted that both
`
`“bounded” and “defined” are used by him to indicate that the active region is
`
`surrounded on all sides by isolation. This testimony is relevant to Petitioner’s
`
`Reply (Paper 22) at 5, where Petitioner states that it “does not agree with PO’s
`
`construction as PO interprets it.” This testimony is relevant because it shows that
`
`the parties have the same construction for the claim term “an active region made of
`
`a semiconductor substrate” and that Petitioner’s expert offers the same
`
`construction as Patent Owner’s expert (“Dr. Glew”) for the claim term “an active
`
`region made of a semiconductor substrate.”
`
`Observation #2: In Ex. 2026 at 84:18-86:12 and 95:4-96:18, respectively,
`
`Shanfield admitted that “you can have a transistor without an isolation region” as
`
`of the priority date of the ’501 patent and that his “proposed construction for the
`
`’501 patent [is] that an active region made of a semiconductor substrate is an area
`
`2 Emphasis added unless noted otherwise.
`
`
`
`1
`
`
`
`
`
`of the semiconductor substrate defined by an isolation region where the transistor
`
`is formed.” This testimony is relevant to page 13 of the Reply where Petitioner
`
`asserts that Dr. Glew’s statement that “semiconductor devices have been made
`
`without isolation regions … [is] misleading.” This testimony is relevant to show
`
`that Dr. Glew’s statement is not misleading because both experts agree that
`
`transistors without isolation existed as of the priority date of the ’501 patent and,
`
`thus, such transistors would not satisfy the “active region” limitation of claim 1 as
`
`construed by both parties (see Observation #1).
`
`Observation #3: The same testimony cited in Observation #2 (Ex. 2026 at 84:18-
`
`86:12 and 95:4-96:18, where Shanfield admitted that “you can have a transistor
`
`without an isolation region” as of the priority date of the ’501 patent and that his
`
`“proposed construction for the ’501 patent [is] that an active region made of a
`
`semiconductor substrate is an area of the semiconductor substrate defined by an
`
`isolation region where the transistor is formed.”) also is relevant to page 10 of the
`
`Reply where Petitioner states “all functional MOSFET transistors have an active
`
`region and Dr. Glew cites no evidence to the contrary.” This testimony is relevant
`
`because it confirms that Dr. Glew’s testimony that transistors without isolation do
`
`not have an active region as required by claim 1 of the ’501 patent is correct
`
`(because the parties’ proposed construction requires that the active region is
`
`defined by isolation region - see Observations #1-2), and establishes that Shanfield
`
`
`
`2
`
`
`
`
`
`agrees with Dr. Glew (and thus provides “evidence to the contrary” of the Reply)
`
`that functional MOSFETs need not have an active region.
`
`Observation #4: The same testimony cited in Observation #2 (Ex. 2026 at 84:18-
`
`86:12 and 95:4-96:18, where Shanfield admitted that “you can have a transistor
`
`without an isolation region” as of the priority date of the ’501 patent and that his
`
`“proposed construction for the ’501 patent [is] that an active region made of a
`
`semiconductor substrate is an area of the semiconductor substrate defined by an
`
`isolation region where the transistor is formed.”) also is relevant to page 14 of the
`
`Reply where Petitioner states “even transistors that do not use isolation regions …
`
`still have active regions … [because] the absence of an isolation region does not
`
`signify the absence of an active region.” This testimony is relevant because it
`
`directly refutes that argument in the Reply and establishes that the absence of an
`
`isolation region does signify the absence of an active region as used in the ’501
`
`patent as acknowledged by the parties’ agreed construction which requires that the
`
`active region is defined by isolation (see Observations #1-3).
`
`SHANFIELD’S TESTIMONY REGARDING FORMATION REGION
`
`II.
`Observation #5: In Ex. 2026 at 97:10-99:15, Shanfield testified that the
`
`“formation region” of a transistor as that term is used in the ’501 patent does not
`
`include the isolation region because, in his opinion, “[t]hat’s not where the
`
`transistor is being formed” even though he admitted that the formation region Rn
`
`
`
`3
`
`
`
`
`
`of the transistor (identified with an Rn bracket in Figure 1) is shown in the ’501
`
`patent as including the isolation region. This testimony is relevant to Ex. 2026 at
`
`105:14-106:18 where Shanfield later testified that the active region is at least as big
`
`or bigger than the formation region as those terms are used in the ’501 patent. This
`
`testimony is relevant because it shows that Shanfield’s assertion that the active
`
`region is bigger than the formation region is based upon an interpretation of
`
`“formation region” that is contradicted by the ’501 patent itself, which describes
`
`the “formation region” as larger than the active region because the formation
`
`region also includes the isolation region that bounds the active region. Compare in
`
`Figure 1 of the ’501 formation region bracket Rn with active region 1a; see also
`
`’501 patent 6:62-7:4 (stating that Figure 2B shows that film 8x is “left only on the
`
`nMISFET formation region Rn” and Figure 2B shows that 8x is on the isolation
`
`region 2).
`
`Observation #6: In Ex. 2026 at 97:10-99:15, Shanfield admitted that the formation
`
`region Rn of the transistor (identified with an Rn bracket in Figure 1) is shown in
`
`the ’501 patent as including the isolation region 2. This is relevant to paragraph 10
`
`of Shanfield’s Reply Declaration where he asserts that “There is nothing in the
`
`’501 patent … that requires each transistor to be isolated from any other
`
`transistor.” This testimony is relevant because it refutes Shanfield’s assertion that
`
`nothing in the ’501 patent requires that each transistor be isolated from other
`
`
`
`4
`
`
`
`
`
`transistors, by acknowledging the teachings in the ’501 patent that the “formation
`
`region” of each MISFET includes isolation.
`
`III. SHANFIELD’S TESTIMONY ON WHETHER IGARASHI FIGURE
`12 HAS ONE ACTIVE REGION OR TWO
`
`Observation #7: In Ex. 2026 at 112:1-113:21, Shanfield admitted that, at his prior
`
`deposition, he testified three times in a row (Ex. 2009 at 91:12-93:10) that there
`
`were two active regions (not one) in Petitioner’s modified Igarashi Figure 12. This
`
`testimony is relevant to paragraph 29 of Shanfield’s Reply Declaration where he
`
`asserts that “A [POSA] would have viewed the region between the two STI in
`
`[modified] Igarashi … as an [singular] active region.” This testimony is relevant
`
`because it shows that Shanfield’s testimony regarding the location or size of active
`
`regions during the course of this trial has been inconsistent, changed repeatedly,
`
`and is thus unreliable.
`
`Observation #8: In Ex. 2026 at 116:22-118:22, Shanfield reviewed his prior
`
`deposition transcript starting at page 93 of Exhibit 2009 and, after searching over
`
`40 pages of testimony that followed his identification of two active regions in
`
`Petitioner’s modified Igarashi Figure 12, he was unable to identify where he
`
`allegedly corrected his testimony to say that there was one active region. This
`
`testimony is relevant to Ex. 2026 at 112:4-11 where Shanfield testified that he
`
`“misspoke” when he testified that there were two active regions and that he
`
`remembered “quickly correct[ing] myself on that point … after thinking about it
`
`
`
`5
`
`
`
`
`
`for a minute.” This testimony is relevant because it directly refutes Shanfield’s
`
`assertion that he misspoke and quickly corrected himself, and demonstrates that his
`
`testimony is inconsistent and unreliable.
`
`Observation #9: In Ex. 2026 at 147:13-148:3, Shanfield testified, in response to
`
`questions by Petitioner’s counsel objected to as leading, that at his prior deposition,
`
`after he had identified three times in a row that there were two active regions in
`
`Petitioner’s modified Igarashi Figure 12 (Ex. 2009 at 91:12-93:10), when he later
`
`referred to “two regions” at 93:16-20 in Ex. 2009, this was not an additional
`
`statement that there were two active regions, but instead was somehow a purported
`
`“correction” of his earlier testimony because he meant that there were two regions
`
`in a single active region. This testimony is relevant to Ex. 2026 at 112:4-11 where
`
`Shanfield testified that he “misspoke” when he testified that there were two active
`
`regions and that he remembered “quickly correct[ing] myself on that point … after
`
`thinking about it for a minute.” This testimony is relevant because it establishes
`
`that Shanfield did not in fact “correct” his prior testimony identifying two active
`
`regions in Ex. 2009 at 93:16-20 (which uses language consistent with his language
`
`at 91:12-93:10), that his alleged “correction” occurred in testimony (Ex. 2009 at
`
`93:16-20) that he himself did not identify when asked by Patent Owner’s counsel
`
`where such correction allegedly occurred even though he starting looking for the
`
`purported correction in Exhibit 2009 at page 93 (Ex. 2026 at 117:23-118:8), and
`
`
`
`6
`
`
`
`
`
`that Shanfield only identified Exhibit 2016 at 93:16-20 as an alleged “correction”
`
`after being improperly led by Petitioner’s counsel’s leading questions, which lays
`
`bare that Shanfield did not “quickly correct himself” or “misspeak”—he provided
`
`inconsistent and unreliable testimony.
`
`Observation #10: In Ex. 2026 at 123:7-15, Shanfield testified that it “was apparent
`
`to me at this point … [that] it didn’t matter anyway whether there was one, two ,
`
`or five active regions [because] [t]he prior art still met the claim limitation.” This
`
`testimony is relevant to the Patent Owner Response at page 61 (where Patent
`
`Owner argued that the Petition failed to identify the boundaries of the alleged
`
`active region in Igarashi Fig. 12) and paragraph 29 of Shanfield’s Reply
`
`Declaration where he asserts that “A [POSA] would have viewed the region
`
`between the two STI in [modified] Igarashi … as an active region.” This
`
`testimony is relevant because it shows that Shanfield doesn’t believe that the
`
`number of active regions is relevant and that it is unnecessary to determine the
`
`boundaries of the alleged “active region” in Petitioner’s modified Igarashi Figure
`
`12, and confirms Patent Owner’s position that the Petition and Shanfield’s original
`
`declaration filed with it failed to demonstrate where an “active region” as claimed
`
`is found in modified Igarashi Fig. 12.
`
`Observation #11: In Ex. 2026 at 123:18-124:18 Shanfield testified that he
`
`couldn’t answer at his prior deposition whether there was one or more active
`
`
`
`7
`
`
`
`
`
`regions located between the STI boxes in Petitioner’s modified Igarashi Figure 12
`
`and that he “still can’t answer it” because he “can’t tell from Igarashi’s drawing as
`
`portrayed.” This testimony is relevant to paragraph 29 of Shanfield’s Reply
`
`Declaration where he asserts that “A [POSA] would have viewed the region
`
`between the two STI in [modified] Igarashi … as an active region.” This
`
`testimony is relevant because it contradicts the testimony in paragraph 29 of
`
`Shanfield’s Reply Declaration testimony, and shows that Shanfield cannot
`
`determine whether there is only one, or more than one, active region in Petitioner’s
`
`modified Igarashi Figure 12.
`
`Observation #12: In Ex. 2026 at 125:13-126:11, Shanfield testified that the
`
`ellipses in Petitioner’s modified Igarashi Figure 12 prevented him from
`
`determining whether there was one or more than one active region and that the
`
`figure had not changed for his Reply Declaration. This testimony is relevant to
`
`paragraph 29 of Shanfield’s Reply Declaration where he asserts that “A [POSA]
`
`would have viewed the region between the two STI in [modified] Igarashi … as an
`
`active region.” This testimony is relevant because it contradicts the testimony in
`
`paragraph 29 of Shanfield’s Reply Declaration, and shows that despite the fact that
`
`Petitioner itself added the ellipses to the figure and Shanfield embraced the figure
`
`by using it in his declaration, he still cannot determine whether there is one or
`
`more than one active region in Petitioner’s modified Igarashi Figure 12.
`
`
`
`8
`
`
`
`
`
`Observation #13: In Ex. 2026 at 126:21-127:18, Shanfield immediately and
`
`without any qualifications agreed that boxes A and B in exhibit 2023 are in one
`
`active region. This testimony is relevant to his prior deposition testimony relating
`
`to his original declaration (Ex. 2010 at 414:8-416:17), where Shanfield was unable
`
`to answer the same question about boxes A and B in exhibit 2005 (stating “that
`
`isn’t … a question I considered and that I believe was relevant to understanding
`
`claim 1”). This testimony is relevant because it demonstrates that at the reply stage
`
`Shanfield readily addressed an issue he did not address in his original declaration
`
`and that he testified that he was unable to answer before Patent Owner filed its
`
`POR, further demonstrating that Shanfield’s testimony is unreliable.
`
`IV. SHANFIELD’S TESTIMONY ABOUT WHETHER CLAIM 1 OF
`THE ’501 PATENT REQUIRES THAT “A SILICON NITRIDE
`FILM” IMPART STRESS TO THE SUBSTRATE
`Observation #14: In Ex. 2026 at 56:17-58:2 and 160:20-23, Shanfield testified
`
`that claim 1 requires that the silicon nitride film induce stress in the substrate and,
`
`at 45:3-18, testified that an etch stop layer cannot induce stress. This testimony is
`
`relevant to Shanfield’s original declaration (Ex. 1002) at paragraphs 48 and 131,
`
`where Shanfield testified that silicon nitride layer 8 in Igarashi is an etch stop layer
`
`and that element 8 meets the requirements of the silicon nitride film limitation.
`
`This testimony is relevant because it directly contradicts the testimony in
`
`Shanfield’s original declaration that Igarashi’s etch stop silicon nitride layer 8
`
`
`
`9
`
`
`
`
`
`meets the silicon nitride film in claim 1, because Igarashi’s layer 8 does not induce
`
`stress which Shanfield alleges is required by claim 1 in the cited testimony.
`
`Observation #15: In Ex. 2026 at 160:20-23, Shanfield reverted to his testimony
`
`that claim 1 “requires that the silicon nitride film induce stress” in the substrate
`
`(Ex. 2026 at 56:17-58:2). This testimony is relevant to Ex. 2026 at 144:1-12 and
`
`145:1-147:8, where in response to improper leading questions from Petitioner’s
`
`counsel, Shanfield testified that claim 1 did not require that the silicon nitride film
`
`induce stress in the substrate. This testimony is relevant because it reveals that
`
`once Petitioner’s counsel stopped asking improper leading questions, Shanfield
`
`reverted to his own (albeit incorrect) testimony that claim 1 requires that the silicon
`
`nitride film induce stress in the substrate, and demonstrates that Shanfield’s
`
`testimony is unreliable because he freely changed his testimony to conform with
`
`the answers Petitioner’s counsel sought even though he had not changed what he
`
`believed was the correct answer.
`
`Observation #16: In Ex. 2026 at 167:14-173:3, 173:10-178:4, Shanfield testified
`
`that claim 1 does not require that the silicon nitride film induce stress in the
`
`substrate. This testimony is relevant to Ex. 2026 at 56:17-58:2 and 160:20-23
`
`where Shanfield repeatedly and consistently testified that claim 1 requires that the
`
`silicon nitride film induce stress in the substrate. This testimony is relevant
`
`because it demonstrates that Shanfield’s testimony is unreliable and that he
`
`
`
`10
`
`
`
`
`
`changed it only in response to Petitioner’s counsel’s improper leading questions,
`
`instructions, and coaching.
`
`Observation #17: In Ex. 2026 at 144:1-12 and 145:1-147:8, Shanfield testified
`
`that claim 1 did not require that the silicon nitride film induce stress in the
`
`substrate and therefore, an etch stop layer could satisfy the silicon nitride film
`
`limitation. This testimony is relevant to Ex. 2026 at 45:3-18 where Shanfield
`
`testified that an etch stop layer cannot induce stress and thus cannot satisfy the
`
`silicon nitride film limitation (Ex. 2026 56:17-58:2 and 160:20-23). This
`
`testimony is relevant because it demonstrates that Shanfield’s testimony is
`
`unreliable and that he changed it only in response to Petitioner’s counsel’s
`
`improper leading questions, instructions, and coaching.
