Q:Do you offer monocrystalline SiC or polycrystalline SiC?
A:We offer monocrystalline SiC currently.
Q:Do you offer monocrystalline SiC or polycrystalline SiC?
A:We offer monocrystalline SiC currently.
Q We actually want to check our reflectance (mirror type) measurement method on an LED structure on a PSS wafer. Would it be possible to get the same LED structure on both a PSS wafer and a single-side polished wafer so we can compare [...]
Q:Dislocation density < 1E8 of GaN on sapphire from what kind of characterization? A:Considering edge dislocation and mixing dislocation and then abtained by XRD
Q: We would like to ask for below. (001) +/- 0.5o Orientation Semi Insulating, C doped Resistivity ≤ 1 – 10 x 108 Ohm-cm3 EPD ≤ 5000 cm-2 1 Side Polished (Ra < 10Å), EPI Ready, Back Side Etched US Semi Standard Flats, No [...]
Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
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: Is it possible to use 4” non-patterned sapphire for fabrication? A:Not possible, currently all the manufacturers swift to patterned sapphire based wafer, including us, however if you really need flat sapphire based wafer, we we can offer 2″ size.
