Abstract:
1. A semiconductor device comprising: a semiconductor substrate including a channel region, a source region and a drain region, wherein the source region and the drain region are on opposing sides of the channel region; and a gate structure present on the channel region of the semiconductor substrate, wherein the gate structure includes an interfacial oxide containing layer in direct contact with the channel region, a high-k gate dielectric layer that is present on the interfacial oxide containing layer, and a semiconducting material gate conductor in direct contact with the high-k gate dielectric layer, wherein the interfacial oxide containing layer has a thickness of 5 Å or less, wherein the semiconducting material gate conductor of the gate structure reduces a strength of an electric field that is produced during burn in when compared to a similarly structured semiconductor device having a metal gate conductor, and wherein the semiconductor device has an operating voltage ranging from 0.5 volts to 0.8 volts.
