Q:As to the wafer dicing – is it possible to get a non-rectangular dicing? such as 6mm x 8mm size?
A:No problem, any size is workable.
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:The ideal waverlength for us is 465 nm, can you offer?. A:It is no problem, but you should know the wavelength should be a range, what we will offer you 465+/-2nm.
Q:Do you have LED wafers that can be used for fabrication of various research oriented structures? If yes, is your wafer unfabricated ? A: Yes, we can offer LED wafers unfabricated without contact, however we also can offer COW(chip on wafer).
Q: Does your 850nm 4″ AlGaAs epi wafer have an etch stop between the P and N layers? A: Yes, there are an etch stop between them.
Q: We need SiC bare wafer, mechanical grade, do you have? A: Sure, mechanical grade is just our dummy grade wafer.
Q: What is the minimum batch size for blue LED wafers on 4 inch sapphire (patterned sapphire)? A:5pcs is ok, but the price would be higher.
