Rudolph Technologies Acquires Selected Assets Related to MKS Instruments’ Yield Dynamics Software Business

Products and R&D Capability Complement Rudolph’s Expanding Presence in Semiconductor Process Control

Flanders, New Jersey (August 11, 2010)—Rudolph Technologies, Inc. (NASDAQ: RTEC), a leading provider of process characterization equipment and software for wafer fabs and advanced packaging facilities, reported today it has acquired selected assets of the Yield Dynamics software business from MKS Instruments (NASDAQ: MKSI-News). The purchase includes selected assets and intellectual property (IP) related to MKS yield management software used by semiconductor manufacturers and fabless semiconductor suppliers. In addition to acquiring the software assets, approximately 35 engineering and applications personnel, most of whom are based in Tianjin, China, will join Rudolph’s Data Analysis and Review Business Unit.

“The products and technology include patented analytical techniques for yield improvement that are complementary to our existing yield management and process control portfolio,” stated Mike Plisinski, Rudolph’s vice president and general manager, Data Analysis and Review Business Unit. “In addition to the technology, we welcome the China personnel to our growing applications and product development team.”

As processes become more challenging, manufacturers are becoming more dependent on data management systems to deliver fast and accurate process information analysis designed to automate decision-making and optimize yield. The Yield Dynamics package includes Genesis® Enterprise software, a fabwide yield management solution that combines parametric and yield optimization in a unified platform with data mining and workflow development across all data sources.

Terms of the cash transaction are undisclosed. Rudolph does not expect the transaction to have any material impact on its operations for the remainder of the year or an impact on any previous financial guidance provided by the company.
