WebJun 1, 2015 · Abstract. In this paper, Hot Carrier (HC) injection mechanism effect on NMOSFETs' Threshold Voltage (V Th ) is examined. The purpose of this work is to predict V Th degradation, under DC hot ... Webii technique. In this thesis, a simple analytical model based on substrate current is used to calculate the density of trapped charges in oxide and interface traps generated and it is a The presence of such mobile carriers in the oxides triggers numerous physical damage processes that can drastically change the device characteristics over prolonged periods. The accumulation of damage can eventually cause the circuit to fail as key parameters such as threshold voltage shift due to … 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. The … See more 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 … See more Hot carrier degradation is fundamentally the same as the ionization radiation effect known as the total dose damage to semiconductors, as … See more • Time-dependent gate oxide breakdown (also time-dependent dielectric breakdown, TDDB) • Electromigration (EM) • Negative bias temperature instability (NBTI) See more The term “hot carrier injection” usually refers to the effect in MOSFETs, where a carrier is injected from the conducting channel in the silicon substrate to the gate dielectric, which usually is made of silicon dioxide (SiO2). To become “hot” and … See more Advances in semiconductor manufacturing techniques and ever increasing demand for faster and more complex integrated circuits (ICs) have driven the associated Metal–Oxide–Semiconductor field-effect transistor (MOSFET) … See more HCI is the basis of operation for a number of non-volatile memory technologies such as EPROM cells.
