Band bending 半導体
웹Known alternately as margin or margining, guard-banding is a way of making sure that if one part of a design fails, the chip still can continue to operate. Guard banding is standard operating procedure in designs at 65nm and above, but as power and performance have become much more entangled with process geometries, adding extra circuitry has ... 웹るので，半導体のバンド曲がり量はFig.1と同じように なる。金属側に電圧を印加して金属のフェルミ準位を bEだけ下げると，バンド曲がり量がゼロになりフラッ トバンド状態が実現する。このとき，フラットバンド電 圧VFBはbE＝fm−fsとなる。
