Dainippon Screen Acquires Cypress’ Silicon Light Machines Subsidiary

Cypress to Integrate SLM’s Ovation Laser Navigation Sensor Business Into Its Consumer & Computation Division

SAN JOSE, Calif., and KYOTO, Japan, July 1, 2008 – Cypress Semiconductor Corp. (NYSE:CY) and Dainippon Screen Manufacturing Co. Ltd. (DNS) of Kyoto, Japan (7735: TokyoStock Exchange) today announced that DNS has acquired Silicon Light Machines (SLM), aCypress subsidiary.

The acquisition will make Silicon Light Machines a wholly owned subsidiary of DNS.Financial terms of the acquisition were not disclosed.

DNS is Silicon Light Machines’ largest Grating Light Valve™ (GLV™) customer. GLVtechnology, SLM’s flagship product, consists of a series of microscopic ribbons suspendedabove a silicon substrate that can be precisely tuned to diffract laser light in different ways. The Micro-Electro-Mechanical System (MEMS) solution is ideal for computer-to-plate (CTP)commercial printing and other imaging applications.

Acquired by Cypress in August 2000, SLM also developed a high-performance laser opticalnavigation sensor technology marketed under the name OvationONS™, which has becomepopular in high-end gaming, and other markets. The OvationONS product line is beingintegrated into Cypress’s core business.

“This transaction reflects our desire to divest businesses that are not optimally aligned withour mission to become a global programmable solutions leader,” said Cypress’s President andCEO, T.J. Rodgers. “The divestiture of SLM’s GLV business-the seventh such transaction intwo years-will bring greater focus to our core business, while the integration of SLM’s opticallaser navigation technology will enable us to expand our suite of programmable solutionsserving the keyboard/mouse market.”

Masanari Tsuda, senior managing director and chief technology officer at DNS said SLM’stechnology will play an important role in the company’s growing business. “Silicon LightMachines’ GLV technology has been an enabler for our leadership position in thermal CTPprinting applications. Now that it is part of DNS, we will be looking to this group to produceproducts that will enable us to expand our imaging technology into other markets.”

Hal Zarem, CEO of SLM said, “SLM will transition from being a subsidiary of its main wafersupplier to becoming a subsidiary of its main customer. I’m pleased to be joining a forwardlookingorganization that is as committed to developing new products for new markets asCypress has been.”

Zarem added, “SLM will continue to serve its existing customers and grow its business as anindependent company under a new corporate umbrella.”About Dainippon Screen Manufacturing Co. Ltd.
