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.
