Hitachi, Ltd.
									LSI Logic Corporation

Hitachi, Ltd. (NYSE: HIT) and LSI Logic Corporation (NYSE: LSI) today announced a wide-
ranging technology agreement that calls for joint development and exchange of 0.10-micron 
device architectures, copper and low K interconnect, advanced lithography, direct write E-beam 
and technical cooperation on embedded DRAM. 

Research teams from both companies are already engaged in the U.S. and Japan in a variety of 
technology development activities. The first result of the alliance will be LSI Logic's embedded 
DRAM solution based upon Hitachi's process technology. LSI Logic expects to begin shipping 
system-on-a-chip products with embedded DRAM cores in mid-2000.

"We are excited to have the opportunity to team with system-on-a-chip leader, LSI Logic, on a 
variety of next generation process technologies," said Hitachi's Kunio Hasegawa, executive vice 
president of Semiconductor and Integrated Circuits. "This comprehensive partnership will advance 
Hitachi's and LSI Logic's technology offerings and will be beneficial for both companies in 
serving their global customers."

"The strategic partnership utilizes the combined resources of two industry leaders to address the 
most costly and complex technology challenges associated with ever-shrinking geometries," said 
Joe Zelayeta, LSI Logic executive vice president of Worldwide Operations. "The culmination of 
this alliance will maximize returns on R&D investments of the respective companies, while 
assisting both of us in meeting the ongoing challenges associated with the rapidly accelerating 
requirements of new technology."

The two companies will contribute different technology strengths to address the issues associated 
with 0.10-micron designs and beyond. "Both Hitachi and LSI Logic will be able to increase their 
market leadership by combining their technology strengths such as Hitachi's advanced process 
technology and LSI Logic's leading logic device technology," said Masahiko Ogirima, Hitachi 
senior vice president of Semiconductor and Integrated Circuits. For example, this partnership 
combines the experience of Hitachi in copper interconnect with LSI Logic's expertise in low K 
dielectric materials.

The initial offering of the comprehensive alliance will be LSI Logic's embedded DRAM (eDRAM) 
product based upon Hitachi's 0.20-micron process technology and LSI Logic's CoreWare(R) 
design methodology. 

"The eDRAM product is specifically designed to provide a cost-effective embedded DRAM 
solution for customers competing in the high-growth networking, telecommunications, wireless, 
computer, storage and consumer markets," said John Daane, LSI Logic executive vice president 
of Communications, Computer and ASIC Products. "The combination of Hitachi's embedded 
DRAM technology and LSI Logic's library of intellectual property cores provides impressive 
offerings to customers that are building products for the rapidly growing Internet infrastructure."

Technology Alliance Overview
- Joint development of advanced device architecture for 0.10-micron transistors including the 
performance, reliability and failure analysis techniques associated with these devices.

- Development of advanced interconnects for 0.13-micron devices, including copper interconnect 
and low dielectric constant insulators for competitive integrated solutions

- Development of 193 nanometer wavelength lithography, reticle technology, prototyping 
techniques for 0.13-micron technology and mass manufacturing.

- Combined research on direct write E-beam technology.

- An embedded DRAM foundry relationship in which Hitachi will manufacture wafers for LSI 
Logic, incorporating LSI Logic's intellectual property libraries.

Glossary of Terms
- Advanced Device Architecture: Design and implementation of advanced transistors used in the 
production of silicon chips.

- Advanced Lithography: Techniques used to define (draw) the transistors and other structures 
onto silicon chip.

- Copper Interconnect: The metal used to connect millions of transistors on a silicon chip.

- Direct write E-beam: The utilization of a focused beam of electrons to draw an electronic 
circuit with lines less than one-thousandth of a millimeter wide directly onto a silicon wafer.

- Embedded DRAM: Blocks of Dynamic Random Access Memory (DRAM) embedded into a 
system-on-a-chip device. Traditionally, DRAMs have been separate components.

- Low K Dielectric: The "quality" of the material insulating the metal interconnect. Low K has a 
significant impact on a manufacturer's ability to produce high performance and high density 
system-on-a-chip solutions.

- Reticle Technology: A mask used to define the millions of structures on a silicon chip.
