As a consequence of BTI, the overall change of the degrading parameters increases the probability that the device fails to meet the specification requirements [ 8 , 9 ] , which may yield a malfunctioning device (though not necessarily destroyed yet).
WebNov 20, 2003 · NBTI finds its origin in both interface trap generation and hole trapping in the gate oxide and is well-known to be more severe in PMOS than in NMOS due to a cumulative charge effect [3]. The way ... NBTI（えぬびーてぃーあい）とは、（英語: Negative Bias Temperature Instability : 負バイアス温度不安定性）の略で、P型半導体(PMOS)の劣化メカニズムのひとつ。古くはスロートラップ現象と呼ばれていた。1990年代はじめに観測された現象で、加工プロセスの微細化に伴い顕在化している。 See more トランジスタのゲート電極に対し基板の電位が負の状態でチップの温度が上昇すると、P型トランジスタの閾値電圧(Vth)の絶対値が徐々に大きくなりトランジスタの特性(Ids , Vth)が変動する現象。負バイアスが印加されない状態 … See more 半導体の設計及び製造プロセスに起因している為、製造プロセスの変更、酸化膜厚の最適化、歪シリコンの採用など。 See more 2013年時点では、メカニズムは解明されていない。しかし、Reaction Diffusion モデルが有力と考えられている 。 1.
