Q:In your web site, the picture of the SiC wafer
does not look like regular, transparent-light green color SiC wafer.
Why is that?
A: Good question, the picture in website is Polarized light image.In regular, it is green color or grey color.
Q: Can you offer some SiC(0001) wafers with low but intentionnal misorientation in the 1° to 2° range? A: We can offer misorientation in low degree, no problem.
Q: What wafer size do you provide with flat sapphire substrate? A:Currently we still can offer 2″ wafer on flat sapphire substrate.
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: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 [...]
Q: We need SiC bare wafer, mechanical grade, do you have? A: Sure, mechanical grade is just our dummy grade wafer.
