Abstract
A polysilicon thin film transistor with a self-aligned LDD structure has a polysilicon layer formed on a transparent insulating substrate. The polysilicon layer consists of a channel region, an LDD structure on two sides of the channel region, and a source/drain region on two sides of the LDD structure. A gate insulating layer is formed on the polysilicon layer, a first metal layer is patterned on the gate insulating layer to cover the channel region, and a second metal layer is patterned on the first metal layer to cover the channel region.
