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: 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.
