Abstract
The present invention generally relates to a thin film semiconductor device having a buffer layer formed between the semiconductor layer and one or more layers. In one embodiment, a thin film semiconductor device includes a semiconductor layer having a first work function and a first electron affinity level, a buffer layer having a second work function greater than the first work function and a second electron affinity level that is less than the first electron affinity level; and a gate dielectric layer having a third work function less than the second work function and a third electron affinity level that is greater than the second electron affinity level.
