High channel mobility 4H-SiC MOSFETs have been demonstrated by phosphorus and arsenic implantation prior to thermal oxidation in N2O. The maximum field-effect mobility of 81 and 114 cm2/Vs were achieved, respectively. The MOSFET fabrication was done on lightly aluminium doped p-type epitaxial layers and on heavily aluminium implanted p-well. |
