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: 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 pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flipchip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. A:LED light is sourcing from mqw light, emitting in all directions, p-GaN is [...]
Q:Can you supply 4″ AlGaAs epi wafers for IR LEDs? A:Yes, we can offer 850nm or 620nm for 4” size.
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: 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:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
