DUAL GATE CONTROL FOR TRENCH SHAPED THIN FILM TRANSISTORS

Abstract:

Disclosed herein are dual gate trench shaped thin film transistors and related methods and devices. Exemplary thin film transistor structures include a non-planar semiconductor material layer having a first portion extending laterally over a first gate dielectric layer, which is over a first gate electrode structure, and a second portion extending along a trench over the first gate dielectric layer, a second gate electrode structure at least partially within the trench, and a second gate dielectric layer between the second gate electrode structure and the first portion.
