Patent ID: 7348609

Claim:
A thin film transistor (TFT), comprising: a conductive structure on a substrate; a non-transparent structure on said substrate and electrically insulated from said conductive structure, wherein said non-transparent structure is placed at the same layer as said conductive structure; a first dielectric layer covering said substrate, said conductive structure, and said non-transparent structure; a first semi-conductive layer on said first dielectric layer, wherein said first semi-conductive layer is over said conductive structure and a portion of said non-transparent structure; a second semi-conductive layer on said first semi-conductive layer, wherein said second semi-conductive layer is over said conductive structure and a portion of said non-transparent structure; a second dielectric layer covering said substrate, said first semi-conductive layer, and said second semi-conductive layer, wherein said dielectric layer has an open region to expose a portion of said second semi-conductive layer; and a patterned semi-conductive layer on said second dielectric layer and filling said open region.
