For blue wafer epi on flat substrate, it would be important to omit / leave out the u-GaN layer as we want to LLO and backside conacting. Is that possible?

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 wafers in one pack as well as the uniformity in one wafer. No metal contact would be perfect as we will employ high temperature process in our application. Do you offer the wafer dicing service as well?

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?
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:I was wondering if you carried any semi-insulating(not doped)SiC or single crystal HPSI SiC?
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.
