| 简介 |
A method of fabricating a rare earth silicide gate electrode on III-N material grown on a silicon substrate includes growing a single crystal stress compensating template on a silicon substrate. The template is substantially crystal lattice matched to the surface of the silicon substrate. A single crystal GaN structure is grown on the surface of the template and substantially crystal lattice matched to the template. An active layer of single crystal III-N material is grown on the GaN structure and substantially crystal lattice matched to the GaN structure. A single crystal monoclinic rare earth oxide dielectric layer is grown on the active layer of III-N material and a single crystal rare earth silicide gate electrode is grown on the dielectric layer, the silicide. Relative portions of the gadolinium metal and the silicon are adjusted during deposition so they react to form rare earth silicide during deposition. |
