Q: 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?
A:Yes, it is no problem, some clients bought our wafers for LLO.

Q:Do you have the optical characterization data for this InGaN wafer? We want to know want wavelength it emits when excited optically. A PL spectrum would be perfect. Also, is the InGaN grown on any buffer layer? What is the uniformity of the Indium composition? Any In segregation or clusters?

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?
