WebFeb 15, 2024 · The channeling effect for ion implantation in Si crystal is well known. 13–19) However, a 4H-SiC wafer generally has a 4° off-cut angle for step epitaxial growth, unlike Si crystals. Therefore, the angular implantation of 4° is adopted for channeling implantation and causes an asymmetric dopant profile. WebIon Implantation. Ion implantation is a material surface modification process by which ions of a material are implanted into another solid material, causing a change in the surface physical and chemical properties of the materials. ...
