SOITEC, Seiko Epson announce new circuits made on SOI

Bernin, France–Seiko Epson has successfully manufactured circuits made on silicon-on-insulator (SOI) UNIBOND material, reports SOITEC. The new circuits will be used by Seiko in a model of its SPRING Drive watch, a high-precision wristwatch.

“We have been working with Epson for several years now in developing the SOI material for low power/low voltage SOI CMOS technology. Today, what we are announcing is a product for commercial application. We provide the material, and Epson produces the chips and the watch,” says SOITEC President Andre Auberton-Herve. “Working with Epson on this consumer application has been extremely rewarding for us. Energy-saving electronic devices will be the typical application of the new decade for circuits made with our UNIBOND product.”

SOITEC’s SOI UNIBOND wafers are produced using commercially available equipment with a proprietary process that uses both ion implantation and wafer bonding technologies. The application of this concept enables the company to produce a high volume of the product, using standard manufacturing equipment. With its new plant, located in Bernin, France, SOITEC now has one of the world’s leading and largest SOI industrial production plants.
