Dummy grade single crystal indium phosphide wafer is available with doping S grown by VGF. The electron concentration of the N-type indium phosphide wafer reaches 1018cm-3, and the indium phosphide resistivity is very low, generally 10-2~10-3Ω·cm. It is mostly used in high-speed optoelectronic devices, such as LD, LED, [...]

After the growth, the silicon carbide single crystal is crystal ingot with surface defects, which cannot be directly used for epitaxy. Therefore, it requires chemical mechanical polishing on silicon carbide. Among the processing skills, spheronization makes the crystal ingot into a standard cylinder; wire [...]
