Abstract

The present disclosure discloses a manufacturing method for an array substrate and an array substrate. The method includes: forming a gate electrode, a gate insulating layer, a semiconductor layer, a source drain electrode layer and a photoresist layer on a substrate; patterning the photoresist layer to form a patterned photoresist layer; performing at least one wet etching on the source drain electrode layer and performing at least one dry etching on the semiconductor layer; performing an ashing processing between the steps of the wet etching and the dry etching. A ratio of a lateral etching rate to a longitudinal etching rate in the at least one ashing processing ranges from 1:0.9 to 1:1.5.
