Q: Please let us know if you could supply below wafer, qty 25/50/300. Gallium Arsenide wafers, P/P 150.00±0.25 mm) 6″Ø×650±25µm, VGF SI undoped GaAs:-[100-2.0°towards[110]]±0.5°, u > 4,000cm²/Vs, Both-sides-polished, 1 Flat 57.5±2.5 mm @ 110±°1, TTV<7µm, BOW<4µm, Warp<10µm, TIR<6µm, Certificate: obligatory, Sealed under nitrogen in single wafer cassette A: Yes, will check the [...]
Q:Our application is for microwave annealing. Therefore, the silicon carbide must be able to absorb microwaves? A:Since the dielectric constant of 6H and 4H are large, so if SiC wafer is as absorbing materials, mainly to achieve through the structure design of Electromagnetic match.I don’t [...]
Q:In your web site, the picture of the SiC wafer does not look like regular, transparent-light green color SiC wafer. Why is that? A: Good question, the picture in website is Polarized light image.In regular, it is green color or grey color.
Q: Regarding your red LED epiwafers, what about the top layer or cap layer on the epiwafer structure? A: As before we have p+GaAs(several nanometers only) in the top layer, however these two years, due to technology innovation, and all foundry remove this layer [...]
Q:I want to know the dopant concentration of SiC substrate that you normally provide ? What is the maximum Nitrogen dopant concentration that you can provide? I am looking for heavily nitrogen doped SiC wafers? A: Our Nitrogen dopant concentration is 1E18/cm3-1E19/cm3, which belongs to heavy dopant.
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.
