Abstract:
The number of masks and photolithography processes used in a manufacturing process of a semiconductor device are reduced. A first conductive film is formed over a substrate; a first insulating film is formed over the first conductive film; a semiconductor film is formed over the first insulating film; a semiconductor film including a channel region is formed by etching part of the semiconductor film; a second insulating film is formed over the semiconductor film; a mask is formed over the second insulating film; a first portion of the second insulating film that overlaps the semiconductor film and second portions of the first insulating film and the second insulating film that do not overlap the semiconductor film are removed with the use of the mask; the mask is removed; and a second conductive film electrically connected to the semiconductor film is formed over at least part of the second insulating film.

Claim (Index 8):
A semiconductor device comprising:\n a first conductive layer over a substrate; a first insulating film over the first conductive layer; an oxide semiconductor film over the first insulating film; a second insulating film over the oxide semiconductor film; a second conductive layer over the second insulating film; a third insulating film over the second conductive layer; a fourth insulating film over the third insulating film; and a third conductive layer over the fourth insulating film, wherein the first conductive layer includes a region overlapping with the oxide semiconductor film, wherein the first insulating film includes a first opening in a region overlapping with the first conductive layer, wherein the second insulating film includes a second opening in a region overlapping with the first conductive layer, and a third opening in a region overlapping with the oxide semiconductor film, wherein the second insulating film has a tapered side surface in the second opening, wherein a top of the tapered side surface is located outside the first opening in a plan view, wherein the second conductive layer includes a region in contact with the first conductive layer through the first opening and the second opening, and a region in contact with the oxide semiconductor film through the third opening, and wherein the third conductive layer includes a region overlapping with the third opening through the third insulating film and the fourth insulating film.
