Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm?
A: Sure, no problem
Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm?
A: Sure, no problem
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?
Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
Q: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 [...]
Q : does the price include fabrication of p and n metal contacts? If not, can you fabricate p and n contacts plus SiO2 passivation based on my design? This can turn to a bigger project. A:Sorry, we can not offer fabrication of p and n [...]
Q:Dislocation density < 1E8 of GaN on sapphire from what kind of characterization? A:Considering edge dislocation and mixing dislocation and then abtained by XRD
Q: After MOCVD, do you anneal the wafer for p-GaN activation? A:Yes! We will anneal the wafer for p-GaN activation
