`

`Patent 6,836,654
`
`1.
`
`2.
`
`I, Steven Harris state and declare as follows:
`
`I am over 18 years of age and am competent to make this Declaration.
`
`I make this Declaration based on my own personal knowledge, based on my
`
`knowledge and review of the business records and practices of the University of
`
`Nevada-Reno Library ("Library").
`
`3.
`
`I am currently employed as the Assistant Dean for Collections and
`
`Knowledge Access Services at the University of Nevada-Reno. I have been
`
`employed in this position since 2013.
`
`4.
`
`I obtained a Master's Degree in Library Science in 1991, and since
`
`that time, I have been employed with academic libraries at various universities
`
`across the United States.
`
`5.
`
`Through my professional experience, I have become knowledgeable
`
`about the Library's normal business practices with respect to how the Library
`
`receives, catalogs, indexes, shelves, and makes available to the public its books,
`
`journals, periodicals, and other collections.
`
`6.
`
`Attached as Exhibit A to this Declaration is a true and accurate copy
`
`of the paper titled "Communication Device Inactivity Password Lock," by Charles
`
`P. Schultz, Motorola Technical Developments, v. 29, Nov. 1996. Exhibit A, pp.
`
`14-15. The exhibit includes photographs of the Library's black bound edition that
`
`holds volumes 27-29 of Motorola Technical Developments. Exhibit A, pp. 7, 17.
`
`DECLARATION OF STEVEN HARRIS

`
`

`

`Patent 6,836,654
`
`7.
`
`The Library has continuously maintained a cataloging system such
`
`that any member of the public could search for the offerings at the Library.
`
`Motorola Technical Developments was part of this system. The Library's records
`
`indicate that the Library regularly received, cataloged, and shelved Motorola
`
`Technical Developments from 1983 (volume 3) to 2000 (volume 42).
`
`8.
`
`In the 1996 timeframe, the Library's cataloging and shelving
`
`procedure for Motorola Technical Developments periodical included placing the
`
`volume on the public shelf upon receipt from the publisher. It was further the
`
`Library's practice to send out for binding three volumes at a time. As noted above,
`
`pages 7 and 19 of Exhibit A are photographs of the physical binder at the Library
`
`that contains the Schultz paper identified in paragraph 6.
`
`9.
`
`The Library has maintained and used in its ordinary course of
`
`business an automated library catalog to track the Library's collections since prior
`
`to 1996. Attached as Exhibit B to this Declaration is a true and accurate screen shot
`
`from the Library's automated library catalog, showing that a record was created on
`
`July 18, 1997 for volumes 27-29 of Motorola Technical Developments. The July
`
`18, 1997 date represents the date when the Library received the physical bound
`
`collection of volumes 27-29 from the binding company.
`
`10.
`
`It was the Library's practice to send out the loose three volumes for
`
`binding after receiving the next one in the collection. That is, volumes 27-29 were
`
`DECLARATION OF STEVEN HARRIS
`
`Page 3
`
`

`

`Patent 6,836,654
`
`sent out for binding after receiving volume 30 of Motorola Technical
`
`Developments. Thus, volume 30 was received prior to July 18, 1997 (the date the
`
`bound collection of volumes 27-29 were received back from the binding
`
`computer).
`
`11. Based on the Library's practice at the time, the Library would re(cid:173)
`
`shelve the bound collection as soon as possible upon receipt of the bound
`
`collection, and typically within one or two business days. Thus, the bound
`
`collection that included Exhibit A would have been back on the public shelves
`
`before July 31, 1997.
`
`12.
`
`It was also the Library's normal practice to date stamp each individual
`
`volume upon receipt from the publisher. Here, the date stamp of volume 29 has
`
`become illegible. However, based on all available information, the Library
`
`received, shelved, and made Exhibit A available to the public, prior to July 18,
`
`1997 because as noted above, the Library shelved volume 29 prior to receiving
`
`volume 30.

`
`COMMUNICATION DEVICEINACTIVITY PASSworRD LOCK
`
`by Charles P. Schultz
`
`When a communication device (radio, phone,
`etc,), is misplaced or left unattended, someone other
`than the authorized user could use it, leaving the
`legitimate user responsible for the consequences,
`financial or otherwise. A password lock feature
`currrently allows users to “lock” their radios from
`use unless a correct password is entered, but this
`feature would not be activated when the device is
`accidentally misplaced, or the user hastily leaves his
`radio behind while attending to some urgent mat-
`ter, An improvement over the current radio lock fea-
`ture would be for the device to become locked after
`it is inactive for a preprogrammedperiod oftime,
`similar to computer screen “locking” programs.
`
`This invention allows the user to program an
`inactivity timer which would be reset each time a
`“physical input” occurs.If the timer expires, the com-
`munication device enters the “locked” mode and
`begins operation on a pre-programmedrevert chan-
`nel which is defined by one ofthe personalities stored
`inthe device’s memory. If the device is operating on
`asystem that requires registration with asite, it will
`unregister prior to locking. The device optionally
`sends an over-the-air signal on the revert channel
`indicating the radio’s ID andits “locked”status. This
`could alert a dispatcher to use a feature such as
`Remote Monitorto aid in locating a lost or stolen
`device. While locked, the device will not route any
`audio to its speaker. The device will receive and
`respond to over-the-air signaling,
`including an
`
`“unlock”transmission from the base station which
`can be used to assist users who have forgotten their
`passwords. The device is subject to the same
`unlocking procedure as the present radio password
`lock feature and, upon unlocking,it will register on
`the current site, if applicable. The devicestoresits
`locked state in non-volatile memory so it remains
`locked when poweriscycled.
`
`For the purposesof this feature, a wide variety
`ofactions are classified as “physical inputs” so legit-
`imate operation will not be interrupted. In addition
`to keypad, button and switch activation, receiving
`bus messages for memory reprogrammingwill reset
`the timer to insure that reprogrammingwill not be
`interrupted. A motion-sensing device and circuit
`could also be added to prevent the device from
`locking while it is being carried around in dispatch
`mode.
`
`Some ofthe devices operating modeswill inhibit
`the activation of the inactivity timer. In order to
`facilitate factory testing orfield servicing ofthe device,
`the inactivity timer will not activate when it is in
`“test mode” or during rekeying. The timerwill also

`
`INTEGRATED STACKED GATE OXIDE AND INTERPOLY OXIDE
`by Craig Cavins, Ko-Min Chang, Craig Swift, Hsing-Huang Tseng and Wayne Paulson
`
`PURPOSE:
`
`For microcontrollers with embedded EEPROM,
`burn-in cost can be as high as $0.25 per part. The
`dominant burn-in failure mode has been the
`EEPROMselect gate failures. A process for 1.2 um
`design rules uses a 350A thermal oxidefor the select
`gate. It is desirable to make this select gate dielec-
`tric more robust in order to reduce or eliminate the
`burn-in failures and thereby eliminate the need for
`acostly burn-in.
`
`The integration ofthe 1.2m processis such that
`the select gate dielectric is formed concurrently with
`the interpoly dielectric for the EEPROMbit cell, and
`the logic gate dielectric is identical to the select gate
`dielectric. The enmeshmentofthese processesgives
`little latitude for significantly improving the quality
`of the select gate dielectric within the confines of a
`conventional approach which is to grow a thermal
`select gate oxide while simultaneously growing a
`thermalinterpoly oxide.
`
`Oneprior art solution is to use an interpoly ONO
`stack with the top oxide layer being a CVD layer
`which can also form atleast part of the peripheral
`transistor dielectric. The disadvantage here is that
`for some self-aligned NVM integrations and for most
`non-self-aligned NVM integrations, the use of an
`ONOinterpoly dielectric requires an additional
`masking step to pattern the ONO.
`
`PROPOSAL:
`
`oxides are well known.! Theprocess sequencestarts
`with a pre-diffusion clean which cleans the single
`crystal silicon surface in the select gate (and logic
`gate) area andcleans the surface ofthefirst poly
`floating gate. Aninitial thin thermal oxide mayor
`may not be grown asthefirst layer of the stacked
`oxide. Then a CVD oxideis deposited. The ratio of
`CVD oxide thickness to final gate oxide thickness
`may be optimized, but a CVD oxide thickness which
`is approximately halfof the final desired thickness
`is a goodstarting point (CVD oxide = 175Afor 1.2
`um process). Finally, an oxidizing annealof the CVD
`layer is performed. This anneal mayalso be designed
`to grow an additional layer of thermal oxide under
`the CVD layer. The temperature and time of the
`anneal should be optimized to achieve the required
`quality and thickness requirements ofthe select gate
`and interpoly oxides as well as to provide the neces-
`sary impetus for diffusion ofany previously introduced
`dopants. Figure 1 shows a cross-sectional represen-
`tation of the EEPROM cell with the conventional
`and proposed process.
`
`SUMMARY:
`Using a stacked gate oxide to simultaneously
`form the select gate and interpoly dielectric for a
`stand-alone or embedded NVM can provide excep-
`tional quality dielectrics which will lead toa burn-in
`failure rate reduction and a significant cost sav ings
`when burn-in is eliminated. This process integra-
`tion is achieved without additional masking steps.
`
`The idea here is to use a stacked gate oxide for
`both the select gate dielectric (also forms the logic
`gate dielectric for the 1.2 wm process) and the
`interpoly dielectric. The advantages of stacked gate
