Stone Pillar Technologies Joins Stratosphere Solutions' ICTrust Partner Program
Partnership Enables Integration of Stone Pillar's TestChipBuilder With Stratosphere's StratoPro Silicon-IP Platform for Improved Parametric Yield

Sunnyvale, CA - December 05, 2007 - Stratosphere Solutions Inc., provider of parametric yield improvement solutions that reduce the impact of variability on performance and parametric yield, today announced that Stone Pillar Technologies™, Inc., provider of semiconductor process technology development software, has become as a member of its ICTrust™ Partnership Program.

Under terms of the partnership agreement, the companies have integrated Stone Pillar's TestChipBuilder with Stratosphere Solutions' StratoPro™ silicon intellectual property (IP) platform to improve parametric yield at 45 nanometer (nm) and below. The automated variability characterization infrastructure, a silicon-proven, high-density, high-resolution test vehicle, is designed to support a technology development eco-system that brings process-intelligence into digital and analog/mixed-signals design flows.

With shrinking technologies of 45nm and below come increased complexities in test vehicle development. This requires design teams to deploy creative methodologies to craft high-density, high-resolution test vehicles, while maintaining the integrity of the amount of data produced to manage parametric yield ramp. Currently, test vehicle creation for mixed-signal and analog devices is a long, tedious process and restricts the ability to increase technology development activities.

Stone Pillar's TestChipBuilder automates the creation of device variations used to populate Stratosphere's silicon-proven parametric active matrix (PAM)-based StratoPro test vehicle IP platform. It enables design teams to efficiently manage their test vehicle IP development, and accelerates test vehicle creation while retaining the ability to accurately measure individual device performance, including parametric device characteristics.

"Array-based process characterization tools such as StratoPro provide tremendous benefits for producing the high volume needed for ramping yields," says Tim Crandle, president of Stone Pillar Technologies. "Combining Stone Pillar's TestChipBuilder with StratoPro accelerates the task of creating and incorporating the thousands of devices supported by this platform and removes a major bottleneck in ramping parametric yield."

"To deliver a parametric yield ramp solution to our sophisticated customer base requires close collaboration across the supply chain," remarks Prashant Maniar, Stratosphere Solutions' chief strategy officer. "The ICTrust Partner Program is a vehicle to accelerate and strengthen that collaboration and deliver a superior solution. Coupling TestChipBuilder with StratoPro accelerates deployment of a sophisticated process characterization solution."
