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:Do these 2” PSS LED wafers have the same epi-stack as the 4” PSS? If not, please send me the diagram with thicknesses. Wavelength can be same: central 455nm A: the 2″ detail layer thickness and structure is same as 4″, no any difference. Wavelength:455nm+/-5nm [...]
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: What wafer size do you provide with flat sapphire substrate? A:Currently we still can offer 2″ wafer on flat sapphire substrate.
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:We want to know the refractive index of these SiC wafers? A:The refractive index is no=2.707, ne=2.755
