SAN DIEGO--(BUSINESS WIRE)--Feb. 14, 2002

PTSC (Patriot Scientific Corp) (OTC BB: PTSC) disclosed more information about its planned acquisition of Aspect SemiQuip International (ASI), a private, closely-held manufacturer of capital equipment used in the production of semiconductor chips.

Commenting on the deal, Douglas N. Dixon, founder and CEO of ASI, said, ``When you look at the combination of these two companies, this acquisition represents a tremendous opportunity to capitalize on our synergistic properties. PTSC is an intellectual property company and ASI is a manufacturer of semiconductor capital equipment. PTSC`s anticipated business model includes IP generation in the micro electro mechanical systems (MEMS) market place.``

Mr. Dixon continued, ``ASI has spent the past two years developing an advanced ultra deep trench plasma etch system. This system is used to micro machine an-isotropic channels in masked silicon wafers. There are many requirements or specifications that the tool we manufacture must meet. High etch rates, usually greater than 4.0 microns per minute, is just one of these specifications. The ability to etch features greater than 100 microns in depth is another requirement, and it is very applicable to processing components for the MEMS market.``

``The result,`` stated Dixon, ``Is that ASI and PTSC have the capability of producing the process, licensing the technology and providing the most advanced equipment to enable companies in the MEMS market place to achieve their goals. Both companies, sharing our joint technologies, will be far ahead of the competition that supplies only one leg of a three-legged stool. The common interest or the synergy as I see it, lies in the fact that we will both be dealing with the same customer base, bringing them not only the process, but also the equipment to accomplish the processing of MEMS components - a little like the razor and razor blade approach to the market we serve.``

ASI`s customer base includes clients known internationally as the world`s leading chipmakers, including companies such as AMD, ST Microelectronics, Texas Instruments, Motorola, and Philips Semiconductor that could benefit from PTSC`s patented technologies.

PTSC signed a letter of intent on February 8, 2002, to acquire 100% of the outstanding shares of ASI. The acquisition, which is scheduled to close on March 15, 2002, is subject to the negotiation of a definitive agreement, completion of further due diligence, and final approval by the boards of directors of the two companies. ASI will continue to conduct business as a wholly owned subsidiary of PTSC from its existing 25,000 square foot facilities near Phoenix, Arizona and its 8,000 square foot facility near Dallas, Texas.
