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:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
Q:In your web site, the picture of the SiC wafer does not look like regular, transparent-light green color SiC wafer. Why is that? A: Good question, the picture in website is Polarized light image.In regular, it is green color or grey color.
Q: We need SiC bare wafer, mechanical grade, do you have? A: Sure, mechanical grade is just our dummy grade wafer.
Q:For 4” pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flip chip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. Is it possible you can share any image of the etched surface of [...]
Q We actually want to check our reflectance (mirror type) measurement method on an LED structure on a PSS wafer. Would it be possible to get the same LED structure on both a PSS wafer and a single-side polished wafer so we can compare [...]
