Patent ID: 8896035

Claim:
A field effect transistor comprising: a semiconductor body comprising: a channel region; a source region adjacent to a first side of said channel region; and a drain region adjacent to a second side of said channel region opposite said first side; a gate structure on said semiconductor body, said gate structure comprising: a gate dielectric layer on said channel region; and, a gate electrode on said gate dielectric layer, said gate electrode having a first section immediately adjacent to said gate dielectric layer on said first side of said channel region and a second section immediately adjacent to said gate dielectric layer on said second side of said channel region, said second section being different from said first section and comprising a phase transition material, said phase transition material being insulative when a voltage difference between said drain region and said source region is above a threshold difference and when said field effect transistor is in an OFF state, and said phase transition material being conductive when said voltage difference between said drain region and said source region is above said threshold difference and when said field effect transistor is in an ON state; and, gate sidewall spacers on opposing sides of said gate structure immediately adjacent to said first section and said second section.
