Dow Corning Files Second Suit Against TOK for Patent Infringement.Business Editors
MIDLAND, Mich.--(BUSINESS WIRE)--July 9, 2001
Dow Corning Corp. filed a second lawsuit against Tokyo Ohka Kogyo Co. Ltd. (TOK) for alleged infringement of three patents relating to the use of hydrogen silsesquioxane (HSQ HSQ Hydrogen Silsesquioxane
HSQ Health Status Questionnaire
HSQ Home Screening Questionnaire (Denver Developmental Materials, Inc.)
HSQ Heat Shield Qualification
HSQ Hatch Sequence
HSQ High Super Quality ) resin technology and its use in the fabrication fabrication (fab´rikā´shn),
n the construction or making of a restoration. of electronic circuits and devices.
The suit, filed June 25, 2001, in Korea with the Yeoju Branch of the Suwon District Court, charges TOK with patent infringement patent infringement n. the manufacture and/or use of an invention or improvement for which someone else owns a patent issued by the government, without obtaining permission of the owner of the patent by contract, license or waiver. on Korean Patent Nos. 95925 ("Metastable met·a·sta·ble
Of, relating to, or being an unstable and transient but relatively long-lived state of a chemical or physical system, as of a supersaturated solution or an excited atom. Silane silane
or silicon hydride
Any of a series of inorganic compounds of silicon and hydrogen with covalent bonds and the general chemical formula SinH(2n + 2). Hydrolyzates and Process for their Preparation"); 95931 ("The Process for Forming a Protective Coating of a Silsesquioxane Resin by Using a Silane Hydrolyzate"); and 282685 ("Method for the Formation of a Silicon Oxide").
This action, in addition to an earlier lawsuit against TOK for infringement of the same patents, is part of a resolve to protect and enforce Dow Corning's patents. The original suit, filed July 18, 2000, in the United States with the Federal District Court for the Eastern District of Texas, is scheduled for trial April 29, 2002.
Dow Corning developed HSQ technology and has established a global distribution and support network for its commercialization as an improved dielectric material for use in electronic devices. The company holds approximately 100 U.S. Patents relating to materials and their use in the semiconductor industry.
"We have been unable to resolve this dispute through discussions with TOK, and so are being forced to bring this matter to the courts for resolution in appropriate jurisdictions around the world," said Mike Little, director, Dow Corning's Semiconductor Fabrication Materials business unit.
HSQ is sold by Dow Corning under the trade name FOx(R) Flowable Oxide. Purchasers of the product are granted usage rights as part of the label licensing agreement. The product was first used in a commercial semiconductor production process in 1994 for integrated circuits featuring 0.5-micron gate lengths. Market acceptance has continued to grow as FOx is now in use in 0.5- to sub-0.18-micron devices.
"We have continued to extend the capability of FOx to meet the needs of successive device generations by leveraging our years of experience and research with HSQ. Last year, we introduced XLK XLK Excel Backup (TM) Spin-On Dielectric, a next-generation material for deep sub-micron device technology based on the same proven HSQ resin," said Little.
