SDR Deposit of the Week: Better processes for better chips

It only makes sense that if you were making solar cells or computer chips that you would choose the best materials for those tasks. It's a no-brainer, right? The problem is that the best materials might be very expensive to use. 

Such has been the case with gallium arsenide, but this may be changing.

Bruce Clemens and Garrett Hayes have developed a new way of making chips from gallilum arsenide that brings down the cost considerably. They created a video that describes a new manufacturing process, and they have preserved that video in the Stanford Digital Repository for you to download and watch!
