Germany’s AZZURO Pushing GaN-on-Si LED Wafer to Cut Manufacturing Time and Cost Germany’s AZZURRO, founded in 2003, focuses on supplying power semiconductor device and LED manufacturers with wafers. AZZURRO owns patents in GaN-on-Si technology. The company’s way is to grow a buffer layer based on GaN material on Si substrate, and then grow a GaN film on the wafer according to different needs of LED and power semiconductor device application. The company noted that currently it can make GaN-on-Si wafer on a 6-inch (150mm) Si substrate, aiming to push it to 8-inch (200mm). LEDinside believes this new manufacturing process will help the migration from the existing LED manufacturing process to silicon substrate manufacturing process. This is LEDinside’s pleasure to have a chance to interview Mr. Erwin Ysewijn, VP Sales & Marketing of AZZURRO to share AZZURRO’s technology and experience. 

The easy migration of LED manufacturing to GaN-on-Si is described in a White Paper released by AZZURRO. Utilizing the company’s 150 mm templates the advantages of GaN-on-Si can be gained after very short design-in times. The White Paper outlines technical hurdles to be overcome when migrating to GaN-on-Si, covers key achievements possible when using the right technology, details the advantages for the move to GaN-on-Si obtainable with templates and shows development solutions to the LED epitaxy engineer. In detail data of GaN-on-Si products is rev...
