WebMar 26, 2024 · 4. Leakage current due to hot carrier injection from the substrate to the gate oxide. The high electric field near the substrate-oxide interface excites electrons or holes, which pass the substrate-oxide interface and into the oxide layer in short-channel devices. Hot carrier injection is the term for this phenomenon. Figure 4. http://large.stanford.edu/courses/2007/ap272/lee1/
WebHot carrier effects have been a serious reliability concern in MOSFET’s ever since the recognition in the mid-seventies, that they can significantly degrade the device characteristics during normal operation. Continuing reduction of device dimensions and increase in channel doping, to achieve higher chip density and speed, is making these ... In MOSFETs, hot electrons have sufficient energy to tunnel through the thin gate oxide to show up as gate current, or as substrate leakage current. In a MOSFET, when a gate is positive, and the switch is on, the device is designed with the intent that electrons will flow laterally through the conductive channel, from … See more Hot carrier injection (HCI) is a phenomenon in solid-state electronic devices where an electron or a “hole” gains sufficient kinetic energy to overcome a potential barrier necessary to break an interface state.
