Abstract:
1. A thermosetting resin sheet for sealing an electronic component, comprising one or more resin components and an inorganic filler, wherein one of the resin components is a thermoplastic resin, and the thermosetting resin sheet has a content by percentage of the thermoplastic resin of a nonzero percentage which is not more than 30% by weight of all of the resin components, wherein a content by percentage of the inorganic filler is from 70% to 95% by weight of the thermosetting sheet, wherein after the thermosetting resin sheet is bonded onto a silicon nitride film formed on a silicon wafer and then set, the thermosetting resin sheet has a shear adhesive strength of 15 MPa or more at 25° C., and 2 MPa or more at 260° C., wherein after the thermosetting resin sheet is bonded onto a copper plate and then set, the thermosetting resin sheet has a shear adhesive strength of 10 MPa or more at 25° C., and 0.5 MPa or more at 260° C., wherein after the thermosetting resin sheet is bonded onto a glass fabric based epoxy resin substrate and then set, the thermosetting resin sheet has a shear adhesive strength of 10 MPa or more at 25° C., and 1 MPa or more at 260° C., and wherein the thermosetting resin sheet further comprises a curing promoter.
