OAI INSTALLS FRONT-SIDE MASK ALIGNER FOR MEMS PRODUCTION LINE AT VERIMETRA, INC.

Versatile, front-side mask aligner facilitates manufacturing of devices featuring the latest MEMS technology.

Milpitas, CA (February 25, 2003) - OAI, a leading Silicon Valley manufacturer of MEMS and semiconductor capital equipment, announced delivery of their Model 500 Front-Side Mask Aligner at Verimetra, Inc. in Pittsburgh PA. Verimetra makes ÒsmartÓmedical devices by embedding a variety of small sensors within the device. The company designs and manufactures sensors using micro-electromechanical systems (MEMS) technology, which is the only method available that produces sensors small enough to be embedded in surgical devices. Verimetra is using the Model 500 system for a variety of applications utilizing the new MEMS manufacturing technology. "We are very satisfied with both system performance and the level of customer service receivedÓ, stated Dr. Michele Migliuolo, Ph.D., president, CEO and co-founder of Verimetra. ÒWe believe the tool will play an important part in our overall product development and production strategy", adds Dr. Migliuolo.

Model 500 Front-Side Mask Aligner System
Built to support the latest advances in MEMS manufacturing technology, the OAI Model 500 is a versatile, economical tool that can be used for R&D as well as pilot development and limited production. The high performance, microprocessor controlled system will deliver ultra precise, submicron printing and level-to-level alignment. It is a high efficiency exposure system with an intensity controlling power supply, vibration isolation feature. Designed for versatility, the Model 500 series mask aligner system has a number of unique, user-configurable features including substrate-to-mask pressure control. It features non-contact, soft contact and soft-through-hard vacuum contact capability, and has a wide range of options including special alignment optics, infrared alignment capability, ultra-precise electronic joy stick, pressure sensitive chucks (for use with brittle substrates), and multi-spectral exposure systems which allow the user to select the exposing wavelength (Near UV, Mid UV or Deep UV). Built with interchangeable subsystem modules, the system can be configured to meet standard applications as well as many unusual requirements.

By incorporating feedback loops on all stage axis, both performance and repeatability is greatly improved. "Our focus is on the development of new photolithography tools and measurement instruments aimed at the global MEMS market", reveals Dr. Charles Turk, President of OAI. "We intend on leveraging our success in the semiconductor business to establish our company as a leader in MEMS technology," Turk adds. By drawing from an extensive family of proven subsystems developed by OAI over the last decade, the company had the ability to focus on Verimetra's specific application requirements.
