Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm?
A: Sure, no problem
Leading manufacturer of compound semiconductor material in China
Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm?
A: Sure, no problem
Q:Could you tell us also what type of 4-H polytype SiC sudstrate you are able to provide? A: Sure.
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:In the test report of blue LED wafers,it shows Vf and IV (mcd). How is this mcd being measured without actually processing the wafer into devices? A:We use prober equipment and contact positive and negative pole, connect current, and then get the voltage and IV.
Q:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
Q:I was wondering if you carried any semi-insulating(not doped)SiC or single crystal HPSI SiC? A: For our semi-insulating SiC substrate, it is V doped, we can not offer High Purity semi-insulating SiC, however we can offer undoped SiC if your quantity is good.
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.
