Accent Announces New High Resolution HBT-Focused DiVA Model Now Shipping.

Business Editors

BEND, Ore.--(BUSINESS WIRE)--March 26, 2003

Accent Optical Technologies (www.accentopto.com), a leading supplier of optoelectronics, wireless and silicon semiconductor process control systems, today announced that it has commenced shipments of its new high-resolution DiVA model, the D225HR.

This model was created in response to customer requests for a high-resolution version for testing NPN HBT devices, and has since been co-opted to test other device types such as enhancement mode MOSFETs on strained silicon (sSi) technology.

Graham Riley, Product Marketing Director, DiVA said, "The D225HR was created to meet a specific need in the market place -- characterizing and testing smaller HBT and BJT devices -- and has since found uses elsewhere. The benefits of fast pulse measurements, resulting in directly measured iso-thermal I-V characteristics, are seen as highly desirable for engineers and scientists working with HBT and other low current technologies like sSi. Also beneficial is DiVA's fast reacting controlled power compliance -- a feature necessary for testing Safe Operating Area (SOA)."

The approach taken by Accent's design team to meet this need started with the proven technology of the D225 model and resulted in the D225HR, which includes enhanced 14-bit A/D technology for superior resolution, along with 25V and 100mA capability. "This latest addition shows our continuing commitment to meet the needs of the market place with the DiVA product line. Based on DiVA's extremely flexible and scalable architecture we will continue to innovate and produce new models to meet our customers needs," stated Riley.
