Definitions
- the present invention relates to a film adhesive, an adhesive sheet, a semiconductor device, and a method for manufacturing the same.
- a stacked MCP Multi Chip Package
- semiconductor elements semiconductor elements (semiconductor chips) are stacked in multiple stages
- higher speed, higher density, and higher integration of semiconductor packages are being promoted.
- the use of copper as a wiring material for semiconductor chip circuits has increased the speed.
- a lead frame made of copper or the like is being used.
- copper has the property of being easily corroded, and from the viewpoint of cost reduction, the coating material for securing the insulation of the circuit surface tends to be simplified, so that the electrical characteristics of the semiconductor package are secured. It tends to be difficult.
- copper ions generated by corrosion move inside the adhesive, and electric signals tend to be easily lost in the semiconductor chip or between the semiconductor chips.
- Patent Literature 1 discloses a complex with a cation having a thermoplastic resin having an epoxy group and no carboxyl group and a heterocyclic compound having a tertiary nitrogen atom as a ring atom.
- An adhesive sheet for manufacturing a semiconductor device, comprising an organic complex-forming compound, is disclosed.
- the present inventors have conducted intensive studies and found that by setting the content of the inorganic filler in the film adhesive to a specific range, while sufficiently suppressing copper ion permeation in the adhesive, it is further excellent in adhesive strength. As a result, the present invention has been completed.
- One aspect of the present invention is a film adhesive for bonding a semiconductor element and a support member on which the semiconductor element is mounted, wherein the film adhesive is a thermosetting resin, a curing agent, and an acrylic rubber.
- the film adhesive is a thermosetting resin, a curing agent, and an acrylic rubber.
- An inorganic filler, and the content of the inorganic filler is 0.5 to 10 parts by mass with respect to 100 parts by mass of the total mass of the thermosetting resin, the curing agent, the acrylic rubber, and the inorganic filler.
- a film adhesive having a thickness of 15 ⁇ m or less.
- the content of the inorganic filler is 0.5 to 10 parts by mass based on 100 parts by mass of the thermosetting resin, the curing agent, the acrylic rubber, and the inorganic filler.
- the content of the inorganic filler is 0.5 parts by mass or more, the adhesive strength of the film-like adhesive, the wafer adhesion, the elastic modulus, and the bulk strength tend to be excellent.
- the content of the inorganic filler is 10 parts by mass or less, copper ion permeation in the adhesive is sufficiently suppressed, and the appearance of the coated surface and the embedding property tend to be excellent.
- the present invention provides an adhesive sheet comprising a base material and the above-mentioned film adhesive provided on one surface of the base material.
- the substrate may be a dicing tape.
- the present invention includes a semiconductor element, a support member for mounting the semiconductor element, and an adhesive member provided between the semiconductor element and the support member, for bonding the semiconductor element and the support member.
