Thin film transistor array substrate and manufacture method of thin film transistor array substrate

Abstract

Provided are a thin film transistor array substrate and a manufacture method thereof, comprising: providing a substrate, and the substrate comprises a first surface and a second surface, which are oppositely located; forming a gate on the first surface; forming a first insulative layer, which covers on the gate; forming a metal oxide semiconductor layer on the first insulative layer; implementing ion implantation to two end regions of the metal oxide semiconductor layer, and the two end regions after the ion implantation respectively are a source and a drain, and a region without the ion implantation is an active layer; forming a second insulative layer, which covers the source, the drain and the active layer; opening a via exposing the source or the drain in the second insulative layer; forming a pixel electrode on the second insulative layer, and connected with the source or the drain through the via.
