Patent ID: 11784153

Abstract:
There are provided a thermosetting resin composition for semiconductor bonding and a thermosetting resin composition for light emitting device which have high thermal conductivity and an excellent heat dissipation property and are capable of reliable pressure-free bonding of a semiconductor element and a light emitting element to a substrate. A thermosetting resin composition comprising: (A) silver fine particles ranging from 1 nm to 200 nm in thickness or in minor axis; (B) a silver powder having an average particle size of more than 0.2 μm and 30 μm or less; (C) resin particles; and (D) a thermosetting resin, wherein an amount of the resin particles (C) is 0.01 to 1 part by mass and an amount of the thermosetting resin (D) is 1 to 20 parts by mass, to 100 parts by mass being a total amount of the silver fine particles (A) and the silver powder (B).
