Q : does the price include fabrication of p and n metal contacts? If not, can you fabricate p and n contacts plus SiO2 passivation based on my design? This can turn to a bigger project.
A:Sorry, we can not offer fabrication of p and n metal contacts, also we can not fabricate p and n contacts plus SiO2 passivation.
Q:Do you have the optical characterization data for this InGaN wafer? We want to know want wavelength it emits when excited optically. A PL spectrum would be perfect. Also, is the InGaN grown on any buffer layer? What is the uniformity of the Indium [...]
Q:As to the wafer dicing – is it possible to get a non-rectangular dicing? such as 6mm x 8mm size? A:No problem, any size is workable.
Q: What wafer size do you provide with flat sapphire substrate? A:Currently we still can offer 2″ wafer on flat sapphire substrate.
Q: Regarding LED epi wafer,does the price include fabrication of p and n metal contacts? If not, can you fabricate p and n contacts plus SiO2 passivation based on my design? This can turn to a bigger project. A: Sorry, we can not offer fabrication of [...]
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: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 [...]
