Abstract:
A manufacturing method of an array substrate, an array substrate and a display apparatus are provided. The manufacturing method includes: providing a base substrate; sequentially forming an active layer and a first insulating layer that covers the active layer on the base substrate; performing one patterning process on the first insulating layer, so as to form a first through hole and a second through hole that expose the active layer in the first insulating layer, and form a first recess at a surface of the first insulating layer; forming a conductive layer on the patterned first insulating layer, with the conductive layer being filled in the first through hole, the second through hole and the first recess; conducting a grinding process to form a source electrode, a drain electrode and a pixel electrode are formed respectively.

Claim (Index 11):
The manufacturing method of the array substrate claimed as  claim 1 , wherein the one pattering process comprises:\n coating a photoresist on the first insulating layer; conducting exposure on the photoresist with a graytone mask or halftone mask, then performing development of exposed photoresist so as to form a photoresist mask layer including a photoresist fully-retained region, a photoresist half-retained region and a photoresist fully-removed region; forming a first blind hole and a second blind hole with a first etching process; removing the photoresist in the photoresist half-retained region with an ashing process; forming the first recess as well as the first through hole and the second through hole that expose the active layer at locations of the first blind and the second blind hole with a second etching process, the first through hole being a stepped hole including a first portion and a second portion, the second through hole being a stepped hole including a third portion and a fourth portion; and removing the photoresist.
