(発明に至る背景)
前記フローティングゲイト電極を陽極酸化して得られる陽極酸化膜と、前記陽極酸化膜の上面および側面に接して形成されるコントロールゲイト電極と、を少なくとも備えた不揮発性メモリが提供される。このことによって上記目的が達成される。
に調節する。
成する。このn-領域は、Pイオン濃度が1×1018atoms/cm3〜1×
1019atoms/cm3となるように調節する。
cm3〜1×1019atoms/cm3となるように調節する。
(2)TFTの動作速度の指標となる電界効果移動度(μFE)が、Nチャネル型TFTで200 〜650cm2/Vs (代表的には250 〜300cm2/Vs )、Pチャネル型TFTで100 〜300cm2/Vs (代表的には150 〜200cm2/Vs )と大きい。
(3)TFTの駆動電圧の指標となるしきい値電圧(Vth)が、Nチャネル型TFTで-0.5〜1.5 V、Pチャネル型TFTで-1.5〜0.5 Vと小さい。
上述の様な優れたTFT特性は、TFTの活性層として、結晶粒界において結晶格子に連続性を有する半導体薄膜を利用している点によるところが大きい。その理由について以下に考察する。
