2-4inch Gallium Nitride (GaN) Templates on Sapphire Substrates/Silicon Wafers

2-4inch Gallium Nitride (GaN) Templates on Sapphire Substrates/silicon wafers

1. What is templates
We use the term "template" to describe our products as they are different to substrates. Specifically, a template is a composite or engineered substrate, where one or more layers are added to the original susbstrate.

2.Application
 
Blue and white LED for room lightings, displays and general use

GaN power switching devices

3.Product available

2" to 4" GaN-templates on FSS and PSS
