Q:We want to know the refractive index of these SiC wafers?
A:The refractive index is no=2.707, ne=2.755
Q:We want to know the refractive index of these SiC wafers?
A:The refractive index is no=2.707, ne=2.755
Q: Can you offer some SiC(0001) wafers with low but intentionnal misorientation in the 1° to 2° range? A: We can offer misorientation in low degree, no problem.
Q:I was wondering if you carried any semi-insulating(not doped)SiC or single crystal HPSI SiC? A: For our semi-insulating SiC substrate, it is V doped, we can not offer High Purity semi-insulating SiC, however we can offer undoped SiC if your quantity is good.
Q: Regarding LED epi wafer,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 [...]
Q:We request for the following items 1. Silicon (Si) single crystal wafers, polished on one side N-type, orientation<100>, Resistivity 5E-3 ohm.cm, Thickness: 0.1 to 0.5 mm 2. Silicon (Si) single crystal wafers, polished on one side P-type, orientation <100>, Resistivity 5E-3 ohm.cm, Thickness: 0.1 to 0.5 [...]
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:Do you sell SiC wafers that are not (0001) plane? For example, (11-20)? A:We can offer a-plane, but the size would be smaller,and should require quantity, do you have size requirement?
