Q:The ideal waverlength for us is 465 nm, can you offer?.
A:It is no problem, but you should know the wavelength should be a range, what we will offer you 465+/-2nm.

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?

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 the two directly?

I am not sure whether practically LLO can be done on the PSS given it is not a flat surface
Q: I am not sure whether practically LLO can be done on the PSS given it is not a flat surface A: “laser lift-off” actually is according to “NL layer” as below image. If the NL layer is GaN layer, when it is heating to constant high [...]
