Abstract:
A method for fabricating a semiconductor device on a substrate comprising the steps of:forming a first conductive layer on the substrate; forming an insulation layer on the first conductive layer; forming a second conductive layer on the first insulation layer and having a first portion overlapping the first conductive layer; removing a portion of the first portion of the second conductive layer that overlaps the first conductive layer to form a top contact hole exposing a portion of the insulation layer; removing the exposed portion of the insulation layer through the top contact hole to form an enlarged contact hole; and forming a conductive pad in contact with the first conductive layer and the second conductive layer through the enlarged contact hole, wherein the conductive pad is in contact with a surface of the second conductive layer and a side of the second conductive layer.
