A method of fabricating an array substrate and an array substrate are disclosed. The array substrate includes a bonding portion, the bonding portion being fabricated by: providing a substrate, and forming a metal layer on the substrate; sequentially depositing a first and a second insulating layer material on the metal layer; etching the first and second insulating layer material respectively at a first etching rate and a second etching rate to form a first insulating layer having a first via hole and a second insulating layer having a second via hole, respectively, thus obtaining a composite insulating layer of a double-layer structure; forming on the composite insulating layer an electrode layer connected to the metal layer through the first and second via holes to form the bonding portion; where the first etching rate and the second etching rate are different, and the first and second via holes are arranged correspondingly.
