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 4):
The method for fabricating the contact hole of the array substrate according to  claim 3 , wherein the array substrate comprises a source and a drain, the source or the drain is formed with the conductive metal structure; and a part of the second photoresist coating, which corresponds to a second contact hole for connecting the source and the drain in the array substrate with the channel layer, is further exposed in an exposure process while the part thereof corresponding to the first contact hole is being exposed; and\n dry-etching the plurality of functional film layers comprises: dry-etching the interlayer insulation layer, and removing a part of the interlayer insulation layer, which corresponds to the first contact hole; ashing the second photoresist coating and the first photoresist coating to remove the second photoresist coating, and to form a via hole through a part of the first photoresist coating, which corresponds to the second contact hole, to expose the interlayer insulation layer; and dry-etching the interlayer insulation layer and the buffer layer to remove a part of the interlayer insulation layer, which corresponds to the second contact hole, to form the second contact hole, and removing a part of the buffer layer, which corresponds to the first contact hole, to form the first contact hole.
