`
`I, Do Hyung Kirn, hereby declare:
`
`1. I am an employee of Samsung Electronics Co., Ltd. I have been employed by Samsung
`
`Electronics Co., Ltd. since September 2003. I am currently Principal Engineer and Legal Counsel
`
`at Samsung Electronics Co., Ltd.
`
`2. I submit this declaration in support of Applied Materials, Inc. 's ("Applied") Reply in
`
`suppmt of its motion for preliminary injunction.
`
`3. Unless indicated otherwise, I have personal knowledge of the facts contained in the
`
`declaration and, if called upon to do so, I could and would testify competently to the matters set
`
`forth herein.
`
`4. I understand that Demaray LLC ("Demaray") alleges infringement of U.S. Patent Nos.
`
`7,544,276 and 7,381,657 by Samsung Electronics Co., Ltd., Samsung Electronics America, Inc.,
`
`Samsung Semiconductor, Inc., and Samsung Austin Semiconductor, LLC (collectively, the
`
`"Samsung Defendants") in Case No. 6:20-cv-00636-ADA in the United States District Court for
`
`the Western District of Texas ("Demaray-Samsung Litigation").
`
`5. I understand that Demaray alleges that the Samsung Defendants infringe by using and/or
`
`configuring reactive magnetron sputtering reactors, including reactors in Applied's Endura
`
`product line, for the deposition of layers, which Demaray identifies as metal nitride layers such as
`
`TaN and/or TiN, in Samsung semiconductor products, including memory products such as
`
`Samsung's DDR4 SDRAM.
`
`6. I also understand that Applied filed an action for declaratory judgment of non(cid:173)
`
`infringement against Demaray in the United States District Court for the Northern District of
`
`California. I further understand that, in that declaratory judgment action, Applied filed a motion
`
`for preliminary injunction to enjoin Demaray from proceeding with the Demaray-Samsung
`
`Litigation during the pendency of the declaratory judgment action.

`
`7.
`
`I understand that Demaray has raised questions as to whether the Samsung Defendants
`
`would agree to be bound by this declaratory judgment action. I have authority to confirm that, if
`
`Applied's motion for a preliminary injunction is granted Samsung Electronics Co., Ltd. does
`
`agree to be bound by the decisions in this action (including appeals) regarding the declaratory
`
`judgment causes of action assert;ed in Applied's First Amended Complaint, including, without
`
`limitation, the non-infringement causes of action-whether based on license, assignment or
`
`technical non-infringement questions-and any patent invalidity causes of action to be asserted in
`
`the future.
`
`8. Samsung Electronics Co., Ltd. (SEC) is a Korean company with its principal offices at
`
`129 Samsung-ro, Yeongtong-gu, Suwon-si, Gyeonggi-do, Republic of Korea.
