Patent ID: 7615413

Claim:
A method of manufacturing a stack-type semiconductor device, comprising: bonding a first semiconductor element on a substrate; affixing an integrated film formed of a dicing film and an adhesive film that are integrated, on a rear surface of a semiconductor wafer having a plurality of element regions which are to be second semiconductor elements, the dicing film having a thickness within a range of not less than 50 μm nor more than 140 μm and a room temperature elastic modulus within a range of not less than 30 MPa nor more than 120 MPa, and the adhesive film having a thickness of 30 μm or more and a room temperature elastic modulus before curing within a range of not less than 500 MPa nor more than 1200 MPa; forming the second semiconductor elements by dividing the semiconductor wafer on which the integrated film is affixed, together with the adhesive film, into the element regions; picking up the second semiconductor element from the dicing film; and bonding the picked-up second semiconductor element on the first semiconductor element by using, as an adhesive layer, the adhesive film affixed on the rear surface of the second semiconductor element.
