Varian Semiconductor to Host vTech Technical Symposium at Semicon West 2005

High-Level Event to Focus on Impact of Materials and Architectures for Sub-45nm Devices

Varian Semiconductor Equipment Associates, Inc. (NASDAQ: VSEA) will host its annual vTech technical symposium on Tuesday, July 12, 2005, at San Francisco's Old Federal Reserve Building. This year's symposium focuses on the impact of materials and architectures for sub-45nm devices.

The all-day symposium begins at 8:45 a.m. and features presentations by leading researchers Dr. Paul Packan (keynote), Intel; Dr. Kyoichi Suguro, Toshiba; Dr. Mark Rodder, Texas Instruments; G. Dan Hutcheson, VLSI Research Inc; Dr. Krishna Saraswat, Stanford University; Dr. Ghavam Shahidi, IBM; Dr. Philip Fisher, AMD; and Dr. Satoshi Nakai, Fujitsu.

"vTech is a great opportunity to share research innovations required to enable continued device scaling," said Peter Nunan, Varian Semiconductor's vice president of technology development. "Just as device scaling brought about OPC (Optical Proximity Correction) and PSM (Phase Shift Mask) to extend lithography capability, scaling is impacting implant requirements for more precise and accurate angle and dose control, while at the same time tightening defectivity specifications. Customers tell us that the opportunity to discuss scaling-related implant challenges and examine potential solutions with their peers in a learning environment is a great benefit. We are looking forward to discussing these challenges and to another successful vTech symposium."

Now in its third year, the vTech technical symposium has quickly become a must-attend event for leading researchers in the industry to discuss technology needs impacting ion implantation. This one-day forum draws together managers, technologists and key decision makers from leading logic, memory and foundry semiconductor manufacturers to discuss transistor trends, especially the challenges facing ultra-shallow junction formation. Each of the distinguished speakers brings a unique perspective on device scaling and various potential solutions.

Due to limited seating, early registration for this event is recommended; however, same-day registration is available. For the complete program details and to register, visit: https://www.vsea.com/seminars.
