M – Metal-Organic Chemical Vapor Deposition (MOCVD) MOCVD is a process used to grow an epitaxial layer of GaN. Pits often appear during the MOCVD process, correlated with the temperature gradients that result as the wafer bows from center to edge.

Towards the beginning of our ABCs of LEDs series, we talked about defects. Here we will tie that in to how defects affect yield of LEDs. K – Kill ratio In looking at a defective wafer through an inspection tool, how do you determine which defects

I – Illumination LEDs are bright, efficient, and quick to react. They have become a substitute for light bulbs in many applications because they use less power, have longer lifetimes, produce little heat, and emit colored light. Using LEDs for

G – Gallium Nitride (GaN) Last week we talked about epitaxy and film, which ties into our discussion this week about gallium nitride. Gallium nitride is used as an epitaxial layer that is grown on the polished upper surface of the sapphire
