S-Band 1mm SiC MESFET with 2W Output on Semi-Insulated SiC Substrate

Abstract
A SiC MESFET structure is successfully prepared on a semi-insulated 50mm SiC substrate using a hot-wall SiC reactor.The doping concentration for the channel layer is about 1.7×1017cm-3,and the thickness is about 0.35μm.An unintentionally n-doped buffer layer is employed between the substrate and the channel layer.A cap layer for Ohmic contact is doped to 1019cm-3.MESFET devices are fabricated using inductively coupled plasma etching and other conventional tools.Power devices with a 1mm gate width are measured and a 2W output at 2GHz is obtained.-
