SEMI Award for North America Given to Thomas DiStefano, John W. Smith, Jr. and Michael Warner for Chip Scale Packaging Technology

HALF MOON BAY, Calif. – January 11, 2011 – SEMI today named Thomas DiStefano, John W. Smith, Jr. and Michael Warner as recipients of the 2010 SEMI Award for North America for contributions to the development and commercialization of Micro Ball Grid Array (μBGA® ) technology. This advancement led to many forms of semiconductor chip scale packaging that enabled cost effective miniaturization. It has had a significant impact on the proliferation of products with smaller form factors, such as handheld phones, cameras, games and other electronics that have since become common. The SEMI Award for North America is the association’s highest honor for technical contribution to the semiconductor industry. The industry awards will be presented during a banquet at the 2011 SEMI Industry Strategy Symposium (ISS) in Half Moon Bay, California this evening.

“Our industry honors Tom DiStefano, John Smith and Michael Warner for their combined efforts to commercialize Micro Ball Grid Array technology while at Tessera Technologies,” said Stanley T. Myers, president and CEO of SEMI. “This critical packaging technology was an important development in the proliferation of smaller personal electronic devices that have spurred the market for semiconductor devices.”

Dr. DiStefano was the founding president of Tessera Technologies and a co-founder of ChipScale Review. DiStefano helped to build Tessera into a world leader in miniaturized packaging. Royalties from U.S. Patents coauthored by DiStefano produced well above $1 billion revenue for Tessera. John W. Smith, Jr. joined Tessera in 1992 as its CEO where he served until his retirement in 2000. Michael Warner, a Tessera Fellow, joined the company in 1994 as the vice president responsible for developing products employing µBGAsolutions for commercial applications.

“The introduction of chip scale packaging by Tessera enabled a decrease in package size and an increase in package frequency while reducing the total power required,” said Bill Bottoms, chairman of the SEMI Award Advisory Committee. “This innovation is now the packaging solution of choice for most memory devices and a significant number of logic devices.  It was initially adapted to meet performance requirements and the high-volume commercialization led to its widespread adoption as a lower-cost packaging alternative.”

The SEMI Award was established in 1979 to recognize outstanding technical achievement and meritorious contribution in the areas of Semiconductor Materials, Wafer Fabrication, Assembly and Packaging, Process Control, Test and Inspection, Robotics and Automation, Quality Enhancement, and Process Integration.

The award is the highest honor conferred by SEMI. It is open to individuals or teams from industry or academia whose specific accomplishments have broad commercial impact and widespread technical significance for the entire semiconductor industry. Nominations are accepted from individuals of North American-based member companies of SEMI. Past award recipients include Walter Benzing and Mike McNealy, Ken Levy, Jean Hoerni, Dan Maydan, Robert Akins and Igor Khandros, among others.
