Abstract:
1. A die bonding agent consisting essentially of (A) an epoxy resin, (B) a curing agent, and (C) an inorganic filler, at least a part of the epoxy resin (A) or the curing agent (B) being a silicone-modified resin having a silicone residue in a molecule, the die bonding agent having a viscosity ratio, V1/V2, ranging (i) from 1.5 to 4 at a temperature of from room temperature to 50° C., and (ii) from 0.5 to less than 1.5 at a temperature at which the die bonding agent hardens in 0.5 hour to 1.5 hours, the viscosities being measured in 10 minutes after the die bonding agent is placed on a sample stage of a Brook Field viscometer, wherein V1 is a viscosity measured by stirring 0.5 ml of the die bonding agent with a No. 51 spindle at 0.5 rpm and V2 is a viscosity measured by stirring 0.5 ml of the die bonding agent with a No. 51 spindle at 5 rpm in the Brook Field viscometer.
