Abstract:
The embodiments of the present disclosure provide an array substrate, a preparation method thereof, and a display device. The preparation method of an array substrate comprises: forming the active layer, a gate insulating layer, the gate metal layer and the patterned photoresist sequentially on a substrate; forming a gate electrode transition pattern by etching a gate metal layer via a patterned photoresist, using a wet etching process and a dry etching process sequentially; and doping an area of the active layer not sheltered by the gate electrode transition pattern with ions to form a heavily doped area of the active layer.

Claim (Index 12):
The preparation method according to  claim 11 , wherein, said forming the active layer, the gate insulating layer, the gate metal layer and the patterned photoresist sequentially on the substrate comprises:\n forming a negative channel metal oxide semiconductor (NMOS) active layer and a positive channel metal oxide semiconductor (PMOS) active layer on the substrate; depositing the gate insulating layer and the gate metal layer sequentially on the substrate with a pattern of the NMOS active layer and the PMOS active layer formed thereon; and forming a PMOS gate electrode and a source/drain doped area of the PMOS active layer; and applying a layer of photoresist, exposing and developing the photoresist to form an NMOS patterned photoresist and a PMOS patterned photoresist, orthographic projections of the NMOS patterned photoresist and the PMOS patterned photoresist on the substrate covering orthographic projections of the NMOS active layer and the PMOS active layer on the substrate respectively.
