Q:Do you offer monocrystalline SiC or polycrystalline SiC?
A:We offer monocrystalline SiC currently.
Q:Do you offer monocrystalline SiC or polycrystalline SiC?
A:We offer monocrystalline SiC currently.
Q:Our application is for microwave annealing. Therefore, the silicon carbide must be able to absorb microwaves? A:Since the dielectric constant of 6H and 4H are large, so if SiC wafer is as absorbing materials, mainly to achieve through the structure design of Electromagnetic match.I don’t [...]
Q:Do these 2” PSS LED wafers have the same epi-stack as the 4” PSS? If not, please send me the diagram with thicknesses. Wavelength can be same: central 455nm A: the 2″ detail layer thickness and structure is same as 4″, no any difference. Wavelength:455nm+/-5nm [...]
Q:For pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flipchip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. A:LED light is sourcing from mqw light, emitting in all directions, p-GaN is [...]
Q:Could you tell us also what type of 4-H polytype SiC sudstrate you are able to provide? A: Sure.
Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
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.
