Abstract:
An improvement is achieved in the reliability of a semiconductor device. A first semiconductor chip includes a semiconductor substrate, a wiring structure formed over the semiconductor substrate, an insulating film formed over the wiring structure, and a first insulating film formed over the insulating film. A second semiconductor chip includes a semiconductor substrate, a wiring structure formed over the semiconductor substrate, an insulating film formed over the wiring structure, and a second insulating film formed over the insulating film. The first insulating film forms an uppermost layer of the first semiconductor chip. The second insulating film forms an uppermost layer of the second semiconductor chip. Each of the first and second insulating films is made of a photosensitive resin film having an adhesive property. The first and second semiconductor chips are stacked such that the first insulating film of the first semiconductor chip and the second insulating film of the second semiconductor chip are in contact with each other.

Claim (Index 9):
A method of manufacturing a semiconductor device including a first semiconductor chip and a second semiconductor which are stacked one over the other, the method of manufacturing the semiconductor device comprising the steps of:\n (a) providing the first semiconductor chip; (b) providing the second semiconductor chip; and (c) after the steps (a) and (b), stacking the first semiconductor chip and the second semiconductor chip, wherein the step (a) includes the steps of: (a1) forming a first wiring structure including one or more wiring layers over a first semiconductor substrate; (a2) after the step (a1), forming a first insulating film over the first wiring structure; (a3) after the step (a2), forming a first photosensitive resin film over the first insulating film; (a4) after the step (a3), subjecting the first photosensitive resin film to exposure and development treatment to pattern the first photosensitive resin film; and (a5) after the step (a4), cutting the first semiconductor substrate, wherein the step (b) includes the steps of: (b1) forming a second wiring structure including one or more wiring layers over a second semiconductor substrate; (b2) after the step (b1), forming a second insulating film over the second wiring structure; (b3) after the step (b2), forming a second photosensitive resin film over the second insulating film; (b4) after the step (b3), subjecting the second photosensitive resin film to exposure and development treatment to pattern the second photosensitive resin film; and (b5) after the step (b4), cutting the second semiconductor substrate, wherein each of the first photosensitive resin film and the second photosensitive resin film has an adhesive property, and wherein, in the step (c), the first semiconductor chip and the second semiconductor chip are stacked such that the first photosensitive resin film of the first semiconductor chip having the adhesive property and the second photosensitive resin film of the second semiconductor chip having the adhesive property come in contact with each other.
