Hitachi and UMC to Establish 300mm Wafer Semiconductor Joint Venture

Hitachi, Ltd. (Hitachi) (NYSE: HIT) and United Microelectronics Corporation (UMC) 
today announced that they have come to an agreement regarding the principal terms of a 
joint venture company to manufacture 300mm wafers with leading-edge process 
technologies of 0.18-micron and beyond. The new company will be based in the N3 
building of Hitachi's LSI Manufacturing Operation in Hitachinaka-city, Ibaraki 
prefecture, Japan. The site is expected to become a strategic manufacturing facility for 
both Hitachi and UMC, combining Hitachi's advanced process and manufacturing 
technology with UMC's advanced technology and world-class silicon foundry expertise. 
Half of the capacity of the joint venture will be reserved for Hitachi's products, with the 
other half reserved for products supplied to UMC's foundry customers. The joint 
venture will be established by the end of February 2000 and start manufacturing 
operations from 2001. 

"The semiconductor market is expected to continue growing, driven by rapidly 
increasing demand for electronic devices, such as PCs, mobile communications and 
digital consumer products. Through the joint venture, Hitachi and UMC will better meet 
the growing demand for advanced ICs, including next-generation system-on-chip 
designs. Hitachi and UMC expect that the joint investment will accelerate the ramping-
up of production and maximize returns on investment for the new company," said 
Hitachi's Tadashi Ishibashi, President & Chief Executive Officer of Semiconductor & 
Integrated Circuits.

"This joint venture will result in one of the world's first 300mm wafer plants in mass 
production. It is being established in response to strong customer demand for advanced 
technologies and increased capacity. With the wealth of technological and 
manufacturing expertise that UMC and Hitachi bring to this venture, we are confident 
of its success. Our foundry customers will welcome this partnership," said Robert Tsao, 
Chairman of UMC. 

Hitachi will contribute its 0.18-micron and beyond process technology, as well as its 
experience in the development of 300mm manufacturing systems. UMC will also 
contribute its 0.18-micron and beyond technology to the company, as well as provide a 
wealth of know-how in silicon foundry operations. The synergy created by the 
combination of the two companies' expertise will ensure that the joint venture leads the 
industry in the mass production of 300mm wafers, and also provides world-leading 
cost-performance and quick turn around times (QTAT).
