Intelligent Epitaxy Technology, Inc. Received 2001 Supplier of the Year Award from Vitesse Semiconductor Corporation for Supplying InP HBT Epiwafers

      Richardson, TX – Intelligent Epixtaxy Technology, Inc. (IntelliEPI), a leader in providing Indium Phosphide (InP) and Gallium Arsenide (GaAs) epitaxial wafers to electronics and optoelectronics industries with its proprietary real time in-situ growth monitoring technology, received the 2001 Supplier of the Year Award from Vitesse Semiconductor Corporation. IntelliEPI has been supplying InP heterojunction bipolar transistor (HBT) wafers grown by molecular beam epitaxy (MBE) systems to Vitesse for high performance communication applications over the past two years.

“Vitesse is pleased to announce that Intelligent Epitaxy Technology, Inc. has been selected as one of our 2001 Suppliers of the Year,” stated Lou Tomasetta, president and CEO of Vitesse. “This award is granted to suppliers who achieve the highest marks in five areas during Vitesse’s qualification process: quality, flexibility, pricing, customer service and strategic advantage.”

“It has been a great pleasure to receive this award from Vitesse. This award acknowledges IntelliEPI’s relentless pursuit of the best quality, pricing, flexibility, and customer service to our customers. For a young company like ours to receive such a distinguished award, it has no doubt been a great encouragement to our entire staff” said Dr. Yung-Chung Kao, the President & CEO of IntelliEPI.

“IntelliEPI has been working with Vitesse on 4-inch InP HBT epiwafers since the first half of 2000 using multi-wafer production MBE systems. The device results on both of our Be- and carbon-doped InP HBT wafers have achieved excellent ft and fmax and have excellent resistivity uniformity across wafer (less than 0.5%) and from wafer-to-wafer. The superior performance, production efficiency, and short lead-time enabled IntelliEPI to work with Vitesse closely in the past years.”
