PDF Solutions® To Acquire IDS Software Systems

Jun 19, 2003 - SAN JOSE, Calif. (PDF Solutions, Inc.)

Acquisition Will Enable PDF To Leverage IDS' Growing Installed-Base To Establish A Broadly Accepted Yield Improvement Software Platform

PDF Solutions, Inc. (Nasdaq: PDFS), the leading provider of process-design integration technologies to enhance IC manufacturability, today announced that it has signed a definitive agreement to acquire IDS Software Systems Inc., a privately held corporation based in Foster City, California.

Under terms of the agreement, PDF Solutions will acquire IDS for $20.0 million in cash and 2,500,000 shares of PDF's Common Stock, resulting in an aggregate consideration value of approximately $50.6 million, based upon the closing price of PDF's common stock on the Nasdaq National Market today of $12.25 per share. In addition, PDF Solutions will assume all of IDS' stock options outstanding immediately prior to the close of the transaction. PDF currently expects the transaction to close in August, subject to customary closing conditions.

As semiconductor companies create products in multiple fabrication and test and assembly facilities, it's crucial that they employ a common yield management system (YMS) to efficiently track progress and quickly identify areas for improvement. The IDS dataPOWERô offering, with more than 1000 installed seats in over 30 of the world's semiconductor companies, is an enterprise YMS solution that is widely accepted by the semiconductor industry.

The dataPOWER products offer enterprise data management with comprehensive analysis and reporting capabilities, intuitive user interfaces and fast processing speeds, a combination that sets dataPOWER tools apart from other statistical analysis systems. The dataPOWER software design focus is on providing the user with integrated, multi-platform compatibility with web access, a wide scope of statistical applications, task automation, feature modularity and high quality.

When fully integrated, the combination of PDF Solutions' integration ramp infrastructure and IDS' dataPOWER functionality will provide customers with greater capabilities for managing product yield improvement. With access to dataPOWER, PDF Solutions' engagement teams will work with customers to more quickly identify key yield improvement areas, implement PDF's yield ramp solutions more rapidly and improve customers' bottom line results.

"Our customers face constant pressure to accelerate IC design ramps to volume production while managing the manufacturability complexities inherent in nanometer semiconductor processes," stated John Kibarian, chief executive officer of PDF Solutions. "The addition of the IDS dataPOWER software and employees to PDF Solutions ñ along with our recent purchase of the WAMAô software product, and related business, from WaferYield, Inc. ñ further enables PDF to help semiconductor companies integrate designs and processes, accelerate yield ramps, and manage yield over the life of their products."

According to Andre Hawit, founder of IDS Software Systems, "The IDS team looks forward to joining PDF Solutions. The combination of PDF Solutions and IDS will allow us to provide an accelerated and expanded product roadmap to our customers."

Upon closing of the transaction, PDF Solutions intends to continue to sell the dataPOWER software as stand-alone products, in addition to offering the software as an option in PDF's integrated yield ramp engagements.
