Patent ID: 7332383

Claim:
A method of forming a switching device of a pixel, comprising the steps of: forming an adhesion layer and a gate on a substrate, wherein the gate is located on the adhesion layer and the adhesion layer comprises TaSi x , TaSi x N y , TiSi x , TiSi x N y , WSi x , WSi x N y , or WC x N y ; forming a first buffer layer on the gate, wherein the first buffer layer comprises TaSi x , TaSi x N y , TiSi x , TiSi x N y , WSi x , WSi x N y , or WC x N y ; forming a gate-insulating layer on the first buffer layer; forming a semiconductor layer on a portion of the gate-insulating layer; and forming a source and a drain on a portion of the semiconductor layer.
