Thin film transistor and fabrication method for same

摘要

A thin film transistor and a method for fabricating the same. The thin film transistor comprises a substrate and a patterned semiconductive layer formed on the substrate, wherein the semiconductive layer comprises a channel region and doped regions adjacent to the channel region. A gate insulating layer is formed on the above structure. A gate electrode is located on the gate insulating layer above the channel region. Source and drain electrodes are located on the gate insulating layer adjacent to the semiconductive layer. A dielectric layer having contact holes is formed on the above structure and a patterned conductive layer is formed on predetermined parts of the dielectric layer electrically connecting the doped regions to the source and drain electrode through the contact holes.
