These problems boost the study of high - k materials as the alternatives of sio2 gate dielectrics . among all high - k gate dielectric materials , hafnium oxide ( hfo2 ) is being extensively investigated as one of the most promising candidate materials due to its superior thermal stability with poly - si , biggish constant and reasonable band alignment . our researches focus on hfo2 dielectrics 高k柵介質材料已經被廣泛地研究來替代sio _ 2 ,以降低柵泄漏電流和改善可靠性,其中, hfo _ 2由于其較大的介電常數、較大的禁帶寬度、與si的導帶和價帶較大的偏置、以及與si的高的熱力學穩定性等特征,被認為是最有希望的替代sio _ 2的柵介質材料之一。
