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: 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: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:Dislocation density < 1E8 of GaN on sapphire from what kind of characterization? A:Considering edge dislocation and mixing dislocation and then abtained by XRD
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 : 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 [...]
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: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 [...]
