Q:Can you supply 4″ AlGaAs epi wafers for IR LEDs?
A:Yes, we can offer 850nm or 620nm for 4” size.
Q:Can you supply 4″ AlGaAs epi wafers for IR LEDs?
A:Yes, we can offer 850nm or 620nm for 4” size.
Q: What wafer size do you provide with flat sapphire substrate? A:Currently we still can offer 2″ wafer on flat sapphire substrate.
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 offer monocrystalline SiC or polycrystalline SiC? A:We offer monocrystalline SiC currently.
Q: The epitaxial wafer on pss substrate is attractive to me, so I want to know the overall efficiency it can deliver. Could you please tell me an efficiency number (lm/w or cd/A or EQE) of the device based on a structure similar to [...]
Q:Could you tell us also what type of 4-H polytype SiC sudstrate you are able to provide? A: Sure.
Q: Regarding blue LED epi wafer, after MOCVD, do you anneal the wafer for p-GaN activation? A:Yes!
