SAN JOSE, Calif., March 27, 2000 - Continuing to lead the programmable logic industry into the most advanced semiconductor manufacturing processes, Xilinx, Inc., (NASDAQ: XLNX) in partnership with UMC announced the immediate availability of the industry's first FPGA family built with copper process technology. The two companies collaborated on copper interconnect technology over the past two years and the process is the foundation for the new Xilinx VirtexTM-E Extended Memory (Virtex-EM) FPGA, also announced today. Virtex-EM is shipping today and is expected to ramp to volume production in the second half of calendar 2000.

"UMC is the first semiconductor foundry to deliver wafers using copper interconnect technology. And, we are pleased to see that Xilinx has effectively implemented this technology to deliver the industry's first copper-based FPGAs," said Fu Tai Liou, UMC chief technical officer. "Previously, wafer yield and return on investment was a concern for those wishing to engage in copper. Now through Xilinx, we have demonstrated that our 0.18-micron copper process is a proven, cost-effective solution for our customers."

"Our partnership with UMC has been very fruitful and has yielded great success," said Wim Roelandts, Xilinx president and chief executive officer. "Since 1997, we have been the first to ship 0.25- and 0.18-micron FPGAs, and now we have extended that leadership with our delivery of the copper-based Virtex-EM family. Our rapid deployment of new processes allows us to quickly bring high-density and high-performance FPGAs to market faster and, in turn, bolster the success of our customers."

Copper: the next generation

The advantage of copper interconnect is its inherently lower resistivity, which minimizes power supply drop throughout the device. In the 0.18-micron, six-layer metal process of the Virtex-EM family, the top two layers deploy copper interconnect. These two layers are used to route clock lines to minimize both clock skew and I/O skew, leading to optimized performance once again. UMC is also ready to manufacture devices that have up to six layers of copper interconnect with low-k dielectrics.

"Copper interconnect enables higher density FPGAs to maintain our drive for greater performance improvements," said Dennis Segers, Xilinx senior vice president and general manager. "This breakthrough lays the groundwork to move quickly down the technology curve to 0.13-micron all-layer copper process and beyond."

The copper process is available in volume production from UMC. "Our fabs are already demonstrating copper yields that are equivalent to our 0.18-micron aluminum process, and we project further improvements throughout the year. Our goal is to continue delivering the highest performance, most reliable copper process in the market so that our customers can begin migrating their designs to this advanced metal process technology today. Furthermore, we are rapidly moving forward to production qualify our all-copper, low-K WorldlogicTM 0.13 technology late this year," stated Dr. Liou.

In the related product announcement today, Xilinx announced the product features and current availability of the aforementioned Virtex-EM FPGA family manufactured by UMC. This announcement marks the industry's first FPGA products with copper interconnect and the initial device incorporates over one million bits of True Dual-Port ™ Block RAM. Production shipments will begin in the second half of calendar 2000.
