Abstract
The present document discloses a semiconductor device structure () comprising a SiC substrate (), an InAlGaN buffer layer (), wherein x1=0-1, y1=0-1 and x1+y1=1, and an InAlGaN nucleation layer (), wherein x2=0-1, y2=0-1 and x2+y2=1, sandwiched between the SiC substrate () and the buffer layer (). The buffer layer () presents a rocking curve with a (102) peak having a FWHM below 250 arcsec, and the nucleation layer () presents a rocking curve with a (105) peak having a FWHM below 200 arcsec, as determined by X-ray Diffraction (XRD). Methods of making such a semiconductor device structure are disclosed.
