Abstract:
A method for manufacturing an array substrate, comprising the steps of:forming a semiconductor layer on a base substrate;forming a first patterned conductive layer on said semiconductor layer;stacking an inorganic material on said first patterned conductive layer and said semiconductor layer to form a first inter-layer insulating film;forming a first hole in said first inter-layer insulating film to extend therethrough to a top surface of said first patterned conductive layer;stacking an organic material on said first inter-layer insulating film to form a second inter-layer insulating film;forming a second hole in said second inter-layer insulating film to extend therethrough and through said first hole to the top surface of said first patterned conductive layer so that said first inter-layer insulating film is not exposed on an inner wall surface of the second hole;annealing said second inter-layer insulating film to thermally contract the organic material forming said second inter-layer insulating film so as to change the shape of said hole while continuously covering said first inter-layer insulating film; andstacking a conductive material on said second inter-layer insulating film to form a second patterned conductive layer connected to said first patterned conductive layer through said second hole.
