NORTH READING, Mass. – June 25, 2008 – Teradyne, Inc. (NYSE: TER) and its Nextest business unit were named ’10 BEST’ suppliers in the 2008 VLSI Research Customer Satisfaction survey. Semiconductor equipment users from around the world recognized Teradyne and Nextest as top ten Automatic Test Equipment (ATE) companies in the 10 BEST ‘Test Equipment’ category and in the overall 10 BEST ‘Large Suppliers of Chip Making Equipment’ category. Customers rated Teradyne first in the product performance category of the survey.

Nextest, who made the prestigious list as an independent company, was acquired by Teradyne early this year.

“Our customer survey represents more than 95% of worldwide chip production. To have both Nextest and Teradyne rated so highly demonstrates the strength that customers value in each of these suppliers and the power they can now deliver as a united force,” said G. Dan Hutcheson, chief executive officer, VLSI Research. “With customers rating Teradyne first for product performance and Nextest third in the equipment uptime category, the survey results clearly demonstrate continued strong customer approval for Teradyne.”

“The recognition is important to us for two reasons,” said Mark Jagiela, president of Teradyne’s Semiconductor Test Division. “First, it’s feedback directly from our customers and we’re grateful for such high marks from our most important audience. Second, as Teradyne marks our 20th consecutive year on the 10 BEST list, we’ve added the strength of another strong performer, Nextest, to our fold. Together, we will continue working to help our customers succeed.”
