Q: Please let us know if you could supply below wafer, qty 25/50/300. Gallium Arsenide wafers, P/P 150.00±0.25 mm) 6″Ø×650±25µm, VGF SI undoped GaAs:-[100-2.0°towards[110]]±0.5°, u > 4,000cm²/Vs, Both-sides-polished, 1 Flat 57.5±2.5 mm @ 110±°1, TTV<7µm, BOW<4µm, Warp<10µm, TIR<6µm, Certificate: obligatory, Sealed under nitrogen in single wafer cassette A: Yes, will check the [...]
Q:Do you offer monocrystalline SiC or polycrystalline SiC? A:We offer monocrystalline SiC currently.
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: Regarding blue LED epi wafer, after MOCVD, do you anneal the wafer for p-GaN activation? A:Yes!
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.
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 [...]
