Abstract

The present invention aims at an improvement in temperature-cycle resistance after packaging in semiconductor devices and also an improvement in moisture-absorbed reflow resistance, and provides an adhesive having a storage elastic modulus at 25° C. of from 10 to 2,000 MPa and a storage elastic modulus at 260° C. of from 3 to 50 MPa as measured with a dynamic viscoelastic spectrometer, and also a double-sided adhesive film, a semiconductor device and a semiconductor chip mounting substrate which make use of the adhesive, and their production process.
