Q:I was wondering if you carried any semi-insulating(not doped)SiC or single crystal HPSI SiC?
A: For our semi-insulating SiC substrate, it is V doped, we can not offer High Purity semi-insulating SiC, however we can offer undoped SiC if your quantity is good.

Q:For pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flipchip packaging. Also I don’t know whether laser liftoff is possible for pss wafer.
A:LED light is sourcing from mqw light, emitting in all directions, p-GaN is [...]
