Q:Do you offer monocrystalline SiC or polycrystalline SiC?
A:We offer monocrystalline SiC currently.
Q:Do you offer monocrystalline SiC or polycrystalline SiC?
A:We offer monocrystalline SiC currently.
Q: Is it possible to use 4” non-patterned sapphire for fabrication? A:Not possible, currently all the manufacturers swift to patterned sapphire based wafer, including us, however if you really need flat sapphire based wafer, we we can offer 2″ size.
Q:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
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:Can you supply 4″ AlGaAs epi wafers for IR LEDs? A:Yes, we can offer 850nm or 620nm for 4” size.
Q: I am not sure whether practically LLO can be done on the PSS given it is not a flat surface A: “laser lift-off” actually is according to “NL layer” as below image. If the NL layer is GaN layer, when it is heating to constant high [...]
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 [...]
