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 |
Q:I want to know the dopant concentration of SiC substrate that you normally provide ? What is the maximum Nitrogen dopant concentration that you can provide? I am looking for heavily nitrogen doped SiC wafers? A: Our Nitrogen dopant concentration is 1E18/cm3-1E19/cm3, which belongs to heavy dopant.
Q:We request for the following items 1. Silicon (Si) single crystal wafers, polished on one side N-type, orientation<100>, Resistivity 5E-3 ohm.cm, Thickness: 0.1 to 0.5 mm 2. Silicon (Si) single crystal wafers, polished on one side P-type, orientation <100>, Resistivity 5E-3 ohm.cm, Thickness: 0.1 to 0.5 [...]
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: 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: 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 atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
