Abstract

A photosensitive adhesive composition comprising: (A) a polyimide having a carboxyl group as a side chain, whereof the acid value is 80 to 180 mg/KOH; (B) a photo-polymerizable compound; and (C) a photopolymerization initiator.

Claims (6)

1. A method for producing a semiconductor device, comprising the steps of:

forming an adhesive pattern by forming an adhesive layer on a semiconductor wafer by laminating an adhesive film on the semiconductor wafer at equal to or below 100° C., and light-exposing and developing the adhesive layer; and

bonding an adherend to the semiconductor wafer via the adhesive pattern.

2. The method for producing a semiconductor device according to claim 1 , wherein the semiconductor wafer comprises an effective pixel region, and the adhesive pattern is formed by light-exposing and developing the adhesive layer so that the effective pixel region is exposed.

3. The method for producing a semiconductor device according to claim 1 , wherein the adhesive pattern is formed by light-exposing and developing the adhesive layer so that an opening is formed.

4. The method for producing a semiconductor device according to claim 2 , wherein the adhesive pattern is formed by light-exposing and developing the adhesive layer so that an opening is formed.
