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: 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 [...]
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: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 [...]
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: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm? A: Sure, no problem
Q:As to the wafer dicing – is it possible to get a non-rectangular dicing? such as 6mm x 8mm size? A:No problem, any size is workable.
