Q:Do you sell SiC wafers that are not (0001) plane? For example, (11-20)?
A:We can offer a-plane, but the size would be smaller,and should require quantity, do you have size requirement?

For 4” pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flip chip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. Is it possible you can share any image of the etched surface of pss?
