LED’s are made using Gallium Nitride (GaN), a semiconductor material that has the best light emitting properties. Plessey’s approach is to exploit the cost benefit of using standard Silicon substrates on which the GaN layer is grown. Plessey achieves this with patented technology. Plessey’s MaGIC process utilizes a thinner GaN layer that means a greater throughput and lower cost in the GaN layer growth process.
