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.

A:No problem, any size is workable.
Q:Our application will be making micro-pillar arrays based on the MQWs for high brightness LEDs and its wavelength tuning. So we do not really care the emission wavelength you provide but we will mind whether the process and emission wavelength would be consist between [...]
Q:Can you supply 4″ AlGaAs epi wafers for IR LEDs? A:Yes, we can offer 850nm or 620nm for 4” size.
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 Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
Q:Do you offer monocrystalline SiC or polycrystalline SiC? A:We offer monocrystalline SiC currently.
Q: Regarding blue LED epi wafer, after MOCVD, do you anneal the wafer for p-GaN activation? A:Yes!
