Abstract
Description
−不可逆変化の効果が無いので、前記部分の誘電体極性化サイクルの間にヒステリシスが現れない。
−純ハフニウム酸化物(HfO2)に関して、マグネシウム(Mg)の導入は、シリコン導電体バンドの閾値に近い値の方向に前記部分の電子の仕事関数を修正する。このシリコン導電体バンドの閾値は、電子の自由状態に対して、おおよそ−4.05evで適合される。本発明によるハフニウムとマグネシウムの混合酸化物の部分は、それ故、PMOSタイプのトランジスタを製造することに対して特に有利である。
−酸素を収容している囲壁の内部の基板を加熱する段階
−前記囲壁の内部上の少なくとも一つの注入開口を、注入器を経て、ハフニウム及びマグネシウムの揮発性先駆耐の一つ以上のソースに接続する段階であって、これらの先駆体は、ソース内で液体形態である段階
