Traditionally Gallium Nitride (GaN) LED devices are produced on either sapphire or silicon carbide (SiC) substrates, due to the good crystal lattice matching between the materials and the GaN, with typically 2” or 4” diameter material being used. Significant effort is being made to grow GaN on ubiquitous larger diameter (6” or greater) silicon wafers, a substrate that offers significant substrate cost reduction, together with the ability to process in automated IC production lines. Reasonable estimates are that potential savings on the order of 80% over tr...
