Abstract
Description
トライド層との界面を形成する。したがって、本発明によって形成されたデバイスは、汚染または表面破壊の結果として生じる界面不整による性能低下、例えば電流リークなどの被害を受けない。
図面中の要素は簡潔性および明瞭性のために図示されており、必ずしも縮尺に応じて描かれていないことを、当業者は認める。例えば、本発明の実施態様の理解を進めるために、図面中の要素のうちの幾つかの寸法は、他の要素に比べて誇張され得る。
したがって化学酸化が有用であり得る。例えば、薄い誘電体は、オゾン水中で基板をリンスして薄い酸化物を成長させることによって、形成されてもよい。熱処理および化学処理の組合せもまた、第2の誘電体20を形成するために用いられてよい。第2のゲート誘電体20はまた、基板を大気または他の酸素含有環境に露出した結果として基板12上に成長した自然酸化物であっても充分である。他の実施態様では、第2のゲート誘電体20は、例えば原子層堆積法によって堆積されることが可能である。
ある。
