EpiWorks completes Phase I expansion for 6” HBT epiwafers

EpiWorks Inc, which manufactures epiwafers for application in optical components, wireless devices and high-speed communication systems, has completed the expansion of its production facility in Champaign, IL, USA, boosting 6" HBT production capacity to over 50,000 wafers per year. The production equipment was purchased last summer, and wafers are already being qualified by customers.

EpiWorks produces both 4" and 6" InGaP HBT epiwafers, grown by MOCVD. “Demand for our InGaP HBT technology has increased steadily over the past two years, and we are very pleased to have successfully completed the first phase of our capacity expansion in an aggressive time-frame,” says president Quesnell Hartmann. “We expect to fill the new capacity by the end of the year and, as this new capacity fills, we plan to begin our phase II expansion. This will double our capacity by 2009 to over 100,000 6" wafers/year,” he adds.

"EpiWorks has been working very closely with several InGaP HBT customers to ensure that we are providing a state-of-the-art InGaP HBT production capability,” says Hartmann. “In addition, we are focused on providing our customers leading-edge, next-generation technology,” adds Dr David Ahmari, executive VP. “The shift toward MOCVD-based pHEMT and integrated HBT/FET technologies has also resulted in the potential for large increases in the demand for our wafers.” The new equipment can also be used to produce pHEMT and integrated HBT/FET technologies.
