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:Do you have the optical characterization data for this InGaN wafer? We want to know want wavelength it emits when excited optically. A PL spectrum would be perfect. Also, is the InGaN grown on any buffer layer? What is the uniformity of the Indium [...]
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: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 [...]
Q: For blue wafer epi on flat substrate, it would be important to omit / leave out the u-GaN layer as we want to LLO and backside conacting. Is that possible? A:Yes, it is no problem, some clients bought our wafers for LLO.
Q:Can you offer SiC mono crystal material with high Thermal Conductivity > 490 W/mK, wafers with thickness: 300-1000um for semiconductor devices heat sinks manufacturing? A: Thermal Conductivity> 490 W/mK is theory value of SiC mono, however we tested some wafers, the thermal conductivity is below [...]
Q: What is the highest temperature and the highest thermal shock that the wafers can withstand? A: At the temperatures higher than 1000 C on the free surface of Si-face of 6H-SiC (0001) the carbon segregation properties are started so that during short time the thin [...]
