Epitaxy: Seeking Crystalline Perfection


Epitaxy is one of the fundamental processes used to make all kinds of semiconductor devices: LEDs, power electronics and, of course, microchips.

Epitaxy was first used in chipmaking to grow ultrapure silicon films – the starting point for making high-performance CMOS transistors. Today, we use epitaxy for a whole lot more.

The term epitaxy means, roughly speaking, “adding order” and that’s exactly what it does. Hot gases react on a surface to “grow” a layer that precisely matches the underlying crystal structure.

In this video, three of Applied’s researchers, David Carlson, Yihwan Kim and Errol Sanchez, delve into the past, present and future of epitaxy technology.

Incidentally, epitaxy is the process that started it all for Applied Materials. David relates a good story about that a couple of minutes in.
