Abstract:
One of methods of manufacturing a semiconductor device of the present invention is as follows: a first conductive layer is formed, a first insulating layer is formed over the first conductive layer, and a second insulating layer is formed over the first insulating layer; then, a first opening portion is formed in the first insulating layer and the second insulating layer to reach the first conductive layer; a mask layer having low wettability to a composition containing a conductive material is formed over the second insulating layer, and a second opening portion larger than the first opening portion is formed in the second insulating layer; subsequently, the first and second opening portions are filled with the composition containing a conductive material to form a second conductive layer.
