Q:Can you supply 4″ AlGaAs epi wafers for IR LEDs? A:Yes, we can offer 850nm or 620nm for 4” size.
Q:We are using 40×40 mil size and 45×45 mil size chips for 1W . And 45×22 or 38x22mil size for 0,5w . Eff. is min. 120lm/w , package form is 3535 ceramic no lens flat type, and 5050 smd flat type.Cct 6500k, cri min 70-75, [...]
Q : does the price include fabrication of p and n metal contacts? If not, can you fabricate p and n contacts plus SiO2 passivation based on my design? This can turn to a bigger project. A:Sorry, we can not offer fabrication of p and n [...]
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 [...]
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: Regarding blue LED epi wafer, after MOCVD, do you anneal the wafer for p-GaN activation? A:Yes!
