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: We need SiC bare wafer, mechanical grade, do you have? A: Sure, mechanical grade is just our dummy grade wafer.
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 [...]
Q: Regarding LED epi wafer,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 [...]
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: 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: The epitaxial wafer on pss substrate is attractive to me, so I want to know the overall efficiency it can deliver. Could you please tell me an efficiency number (lm/w or cd/A or EQE) of the device based on a structure similar to [...]
