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 wafer size do you provide with flat sapphire substrate?
A:Currently we still can offer 2″ wafer on flat sapphire substrate.
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:We want to know the refractive index of these SiC wafers? A:The refractive index is no=2.707, ne=2.755
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: After MOCVD, do you anneal the wafer for p-GaN activation? A:Yes! We will anneal the wafer for p-GaN activation
Q: Is it possible to use 4” non-patterned sapphire for fabrication? A:Not possible, currently all the manufacturers swift to patterned sapphire based wafer, including us, however if you really need flat sapphire based wafer, we we can offer 2″ size.
Q:Do you offer monocrystalline SiC or polycrystalline SiC? A:We offer monocrystalline SiC currently.
