Webvice. In the bulk MOSFET, the body is hardly used as an active terminal because of the large body capacitance inherited from well or substrate capacitance. For specific applications, how-ever, more efficient circuit operation can be achieved if the body is used as an active terminal [1]. In this work, a new operation Web1 Feb 2024 · For heavily doped pn junction of drain/source and substrate regions, the band-to-band tunneling (BTBT) effect dominates the reverse bias leakage current. In band-to-band tunneling, electrons tunnel directly from the valence band of the p region to the conduction band of the n region. BTBT is visible for electric fields greater than 10 6 V/cm.
