Abstract :
A novel silicon-nitride-oxide-silicon (SNOS) gate-controlled, normally-off p-i-n switch (SGPINS) is proposed and experimentally demonstrated. The normally-off of the SGPINS is implemented by using a fully depleted n--channel region that is controlled by an SNOS trench gate. The device has a threshold voltage of 7 V and an avalanche breakdown voltage of ~1000 V. ON-state voltage drop of the SGPINS is 1.7 V, and is ~0.6 V lower than that of an IGBT with the same non-punch-through structure, resulting in ~26% reduction in the conduction loss.
