Q: For GaN on sapphire, could you please let us know which side is epi-ready?
A: Ga-face,epi-ready and N face is connecting to sapphire.

Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
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.
The InGaAsP material epitaxially grown on the InP substrate is an important material for the fabrication of optoelectronic and microwave devices. The emission wavelength of InGaAsP / InP laser structure covers 1.0-1.7μm, covering two low-loss windows of 1.3μm and 1.55μm for silica fiber communication. [...]
Q We actually want to check our reflectance (mirror type) measurement method on an LED structure on a PSS wafer. Would it be possible to get the same LED structure on both a PSS wafer and a single-side polished wafer so we can compare [...]
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: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm? A: Sure, no problem
