Abstract:
The present disclosure discloses a manufacturing method of a thin film transistor, including: forming a gate layer on a substrate; forming a gate insulating layer on the gate layer and the substrate; forming an active layer on the gate insulating layer; and simultaneously forming a source and a drain formed on the active layer by a combination of a chemical plating method and a lift-off method. In the present disclosure, the chemical plating method is combined with the lift-off method, so that the wet-etching method is not used for forming the source and the drain, and thus the IGZO at the channel is not required to be protected by the etching-stop-layer. Therefore, while simplifying the production process, but also can reduce costs.

Claim (Index 1):
A thin film transistor manufacturing method, comprising:\n forming a gate layer on a substrate; forming a gate insulating layer on the gate layer and the substrate; forming an active layer on the gate insulating layer; and simultaneously forming a source and a drain formed on the active layer by a combination of a chemical plating method and a lift-off method; wherein the simultaneously forming a source and a drain formed on the active layer by a combination of a chemical plating method and a lift-off method comprises: coating a photoresist layer on the gate insulating layer and the active layer; patterning the photoresist layer to remove a photoresist layer at a position where the source and the drain are to be formed to expose the active layer; doping the exposed portion of the active layer to form a first conductor portion and a second conductor portion; and disposing the source on the first conductor portion, and disposing the drain on the second conductor portion; using a chemical plating method to form a metal film layer on a remaining photoresist layer and an exposed portion of the active layer; and stripping the remaining photoresist layer with a stripping liquid to peel off the metal film layer on the remaining photoresist layer to form the source and the drain.
