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 metal contacts, also we can not fabricate p and n contacts plus SiO2 passivation.
Q:I was wondering if you carried any semi-insulating(not doped)SiC or single crystal HPSI SiC? A: For our semi-insulating SiC substrate, it is V doped, we can not offer High Purity semi-insulating SiC, however we can offer undoped SiC if your quantity is good.
Q: After MOCVD, do you anneal the wafer for p-GaN activation? A:Yes! We will anneal the wafer for p-GaN activation
Q: We would like to buy LT-GaAs, could you please recommend the specs that suit for the application?

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: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 [...]
