Oki Electric and UMC/UMCJ Broaden Semiconductor Business Partnership
Oki begins to market 0.15um/0.13um System LSI (SOC) with UMC/UMCJ, and also
joins UMCfs Gold IPTM Program to offer strategic IPs including µPLAT® design platform


Tokyo and Chiba, Japan, Sep. 4th, 2002 - Oki Electric Industry Co., Ltd. (TSE:6703) together with UMC (NYSE: UMC) and UMCfs Japan based subsidiary UMC JAPAN (UMCJ), today announced that the companies have reached a comprehensive business agreement for the leading-edge process foundry partnership which also includes System LSI design alliance for mutual IP development and availability.

Oki will align itself with UMCfs process design rules and target parameters of transistor characteristics for the 0.15um process generation. The process is also compatible with each companyfs mask data level, which will allow Oki to utilize UMC/UMCJfs production capacity when needed to assure stable supply for large volume requirements or to respond to sudden increases in demand. For advanced 0.13um technology and beyond, the broadened foundry partnership will enable Oki to offer competitive system LSI products in a timely fashion and utilize UMC and UMCJfs advanced process technology. This will allow Oki to focus its investments and resources more effectively on developing System LSI products and design properties.

The design alliance aspect of the agreement incorporates Oki into UMCfs Gold IPTM program as a Design Plus partner. According to the agreement, Oki will port its entire portfolio of strategic IPs such as Okifs ARM® based integration platform and design environment, gµPLAT®h for use on the foundryfs advanced technologies. Oki will also make available total solution services to UMCfs foundry customers including its design supports and IP licensing services.

Katsuhiko Sano, President of Silicon Solutions Company at Oki Electric commented, gBroadening our long-term business partnership with UMC/UMCJ is one of Okifs System LSI development strategies. With this agreement, Oki will be able to provide System LSI products to customers timely with a total service solution. This comprehensive agreement will also enable us to focus our resources more effectively on developing improved design environments.h

John Hsuan, UMC Vice Chairman and CEO, said, gOki will greatly increase its ability to deliver market winning products by concentrating its resources on LSI design and development while leveraging UMCfs prowess in technology development and cost-efficient manufacturing. This move is historic in that it marks the first example of an IDM company in Japan moving towards the fabless business model that has proven so successful in the USA and other countries over the past decade. We are also extremely happy to offer Okifs extensive IP portfolio to our other foundry customers. This is definitely a win-win situation for UMC and Oki that has benefits for other companies in the industry as well.h

Currently, UMCJ is producing 0.35um / 0.22um products for Oki.
