August 15, 2015 Think of this page as the ultimate MMIC supplier guide. A little history has been included for your information and entertainment here and there.

Xpert Semiconductor Inc.
Xpert is a supplier of epitaxially-grown GaAs wafers, in both four and six inch diameters. They are located in Taiwan, no doubt a convenient distance to Win Semi. They plan to double the capacity of their 4000 square foot facility to manufacture 3000 six-inch wafers per month by the end of 2004. That's enough GaAs to easily tile the roof of a good-sized house each year!

Here's a photo of one of Xpert's six-inch GaAs wafers, which is an image of something that most MMIC companies have never seen up close (thanks to Angela!)
