[11p-N304-4] Evaluation of Mg2Si substrate using X-ray rocking curve measurement
Keywords:semiconductor, Mg2Si, X-ray
Mg2Si, which has a energy band width of about 0.6 eV at room temperature, is expected to be a low-cost material for photodetectors in the short-wavelength infrared region suitable for mass production. At present, the surface processing conditions and crystallinity of Mg2Si wafers have not been studied, and it is necessary to establish a wafer processing technology suitable for the fabrication of photodetectors. In this study, we polish Mg2Si and report on the evaluation of the crystallinity of the polished surface using the peak tail of the XRC measurement.
