<p>Disclosed is a resin paste for die bonding comprising a butadiene homopolymer or copolymer (A) having a carboxylic acid terminal group, a thermosetting resin (B), a filler (C), and a printing solvent (D), wherein the elastic modulus of the resin paste following drying and curing is within a range from 1 to 300 MPa (25°C). The solid fraction is preferably from 40 to 90% by weight, the thixotropic index is preferably from 1.5 to 8.0, and the viscosity (25°C) is preferably from 5 to 1,000 Pa·s. Using this resin paste, a semiconductor device is produced by a method comprising (1) applying a predetermined quantity of the resin paste to a substrate, (2) drying the resin paste to effect B-staging of the resin, (3) mounting a semiconductor chip on the B-staged resin, and (4) conducting post-curing of the resin.</p> |
