Q: Can you offer some SiC(0001) wafers with low but intentionnal misorientation in the 1° to 2° range?
A: We can offer misorientation in low degree, no problem.
Leading manufacturer of compound semiconductor material in China
Q: Can you offer some SiC(0001) wafers with low but intentionnal misorientation in the 1° to 2° range?
A: We can offer misorientation in low degree, no problem.
Q: Regarding your red LED epiwafers, what about the top layer or cap layer on the epiwafer structure? A: As before we have p+GaAs(several nanometers only) in the top layer, however these two years, due to technology innovation, and all foundry remove this layer [...]
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: Does your 850nm 4″ AlGaAs epi wafer have an etch stop between the P and N layers? A: Yes, there are an etch stop between them.
Q: We need SiC bare wafer, mechanical grade, do you have? A: Sure, mechanical grade is just our dummy grade wafer.
Q:Do you sell SiC wafers that are not (0001) plane? For example, (11-20)? A:We can offer a-plane, but the size would be smaller,and should require quantity, do you have size requirement?
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.
