Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm? A: Sure, no problem
Q We actually want to check our reflectance (mirror type) measurement method on an LED structure on a PSS wafer. Would it be possible to get the same LED structure on both a PSS wafer and a single-side polished wafer so we can compare [...]
Q: What is the minimum batch size for blue LED wafers on 4 inch sapphire (patterned sapphire)? A:5pcs is ok, but the price would be higher.
Q: After MOCVD, do you anneal the wafer for p-GaN activation? A:Yes! We will anneal the wafer for p-GaN activation
