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: 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: 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: Regarding blue LED epi wafer, after MOCVD, do you anneal the wafer for p-GaN activation? A:Yes!
Q: The epitaxial wafer on pss substrate is attractive to me, so I want to know the overall efficiency it can deliver. Could you please tell me an efficiency number (lm/w or cd/A or EQE) of the device based on a structure similar to [...]
Q: Could you please provide information about standard epi structure of InGaAsP/InP wafer? A: Here we only can offer you general structure: Layer Material 6 InP 5 GaInAs 4 GaInAsP 3 InP 2 AlGaInAs MQW PL 1500-1560nm 1 InP buffer InP substrate
