Abstract:
A method for fabricating a contact hole of an array substrate, an array substrate and a display device are disclosed, the method includes: coating a topmost layer with a first photoresist coating, exposing but not developing a part of the first photoresist coating, corresponding to a first contact hole, in an exposure process; coating the first photoresist coating with a second photoresist coating, exposing a part of the second photoresist coating, corresponding to the first contact hole, in an exposure process; developing and removing exposed parts of the first and second photoresist coatings, wherein a size of a removed part of the second photoresist coating, corresponding to the first contact hole, is smaller than a size of a removed part of the first photoresist coating, corresponding to the first contact hole; and removing parts of functional film layers, corresponding to the first contact hole, to form the first contact hole.

Claim (Index 1):
A method for fabricating a contact hole of an array substrate, the method comprising:\n forming a first metal layer on a substrate, and forming a first metal pattern in a patterning process; forming a plurality of functional film layers sequentially above the first metal layer; coating a topmost one of the plurality of functional film layers with a first photoresist coating, and exposing but not developing a part of the first photoresist coating, which corresponds to a first contact hole for connecting a conductive metal structure with the first metal layer, in an exposure process; coating the first photoresist coating with a second photoresist coating, and exposing a part of the second photoresist coating, which corresponds to the first contact hole, in an exposure process; developing and removing exposed parts of the first photoresist coating and the second photoresist coating; wherein a size of a removed part of the second photoresist coating, which corresponds to the first contact hole, is smaller than a size of a removed part of the first photoresist coating, which corresponds to the first contact hole; and dry-etching the plurality of functional film layers, and removing parts of the plurality of functional film layers, which correspond to the first contact hole, to form the first contact hole.
