  • Patent number: 9738763
    Abstract: Provided is a resin sheet, wherein in a stress measurement in which a dynamic shear strain is applied in a direction parallel to a surface, the difference between a loss tangent as measured when a strain amplitude is 10% of the sheet thickness and a loss tangent as measured when the amplitude is 0.1% is equal to or greater than 1 at a temperature of 80° C. and a frequency of 0.5 Hz. The resin sheet of the present invention can provide a semiconductor device with excellent connection reliability, wherein air bubbles and cracks are less likely to occur in the resin sheet. In the resin composition of the present invention, aggregates are less likely to occur during storage. The resin sheet obtained by forming the resin composition into a sheet has good flatness.
