Abstract
Depletion-mode n-channel metal-oxide-semiconductor field-effect transistors were fabricated on n-type β-SiC (111) thin films epitaxially grown by chemical vapor deposition on the Si (0001) face of 6H α-SiC single crystals. The gate oxide was thermally grown on the SiC; the source and drain were doped n+ by N+ ion implantation at 823 K. Stable saturation and low subthreshold current were achieved at drain voltages exceeding 25 V. Transconductances as high as 11.9 mS/mm were achieved. Stable transistor action was observed at temperatures as high as 923 K, the highest temperature reported to date for a transistor in any material.
