Oki Electric and UMC JAPAN Jointly Develop 0.22-um CMOS Process

- Oki Begins Marketing 0.22-um ASICs Based on a Newly Developed Process -

Tokyo and Chiba, Japan, February 4, 2001 - Oki Electric Industry Co., Ltd. and UMC JAPAN (UMCJ) today announced that the companies have succeeded in the joint development of a 0.22-um system LSI process, enabling them to offer top-class system LSI in terms of performance and density in its class, and enabling both companies to share design rules effectively. Oki Electric will now begin sales and marketing of ASIC, MG7xN family, produced using this newly developed process.
"The success of this joint development with UMCJ extends Okifs commitment as a leading provider of competitive products in 0.25-um class," said Akira Kamo, Vice President of Silicon Solutions Company at Oki Electric, adding that, "this is a major milestone in our collaboration with UMCJ, following the foundry agreement in the area of 0.35-um and 0.25-um processes in 2000."
"Our alliance with Oki Electric is in response to the high 0.25-um demand in the market," said Makoto Sasaki, Officer of Sales Marketing Department at UMCJ. "Together, both companies combine highly complementary sets of technologies, skills and expertise, to provide customers with superior semiconductor products."
In the process developed by Oki Electric and UMCJ, the companies shared design rules and target parameters relating to transistor characteristics. The process is also compatible with each companyfs mask data level, enabling Oki to use UMCJfs wafer-production capacity effectively and flexibly to respond to sudden increases in demand or to stabilize supply volume. The process is introduced to Miyagi Oki Electric Co., Ltd., a wholly owned subsidiary of Oki Electric, and to UMC JAPAN Tateyama Plant.
While using 0.25-um generation manufacturing equipment, the process permits an increase in the density of system LSIs. Oki Electric has established a new design environment, including libraries, based upon this process, and will begin sales and marketing of new ASIC, MG7xN family, to the worldwide market in February 2002. This MG7xN family is 20% faster, offers a 20% reduction in power consumption, and features a 70% increase in density relative to the current MG7xP family (0.25-um process ASIC) per gate. Oki intends to market the MG7xN family for use in network equipment, PC peripherals, and consumer electronics products.
"By expanding its ties with UMC JAPAN and UMC from a foundry contract to a production collaboration involving advanced-process technology, Oki is able to further strengthen its production strategy. We now intend to initiate discussions regarding future business opportunities, including the possibility of collaboration beyond 0.13-um process technology," said Kamo of Oki Electric.
"We are happy to be working with IDMfs (Integrated Device Manufactures) like Oki Electric. By capitalizing on our expertise, which has resulted in the shortest production-cycle time in the industry, UMCJ will continue to provide a stable supply of semiconductors at appropriate prices with a short turnaround time to all of our partners, including Oki Electric," said Sasaki in UMCJ.
