Abstract
A curable silicone composition for die bonding use contains at least (A) an organopolysiloxane having at least two alkenyl groups per molecule, (B) an organopolysiloxane having at least two siloxane units each represented by the formula: RHSiO (wherein R represents a monovalent hydrocarbon group having 1 to 12 carbon atoms and having no aliphatic unsaturated bond) per molecule, (C) a platinum-group metal-based catalyst for hydrosilylation reactions, (D) a hydrosilylation reaction inhibitor and (E) an adhesiveness-imparting agent, wherein the scorch time (ts1), which is defined in JIS K 6300-2, at a die bonding temperature is 20 to 60 seconds, and the 90% vulcanization time [tc(90)] with respect to the maximum torque value during the vulcanization time of 600 seconds is 300 to 500 seconds. The curable silicone composition for die bonding use according to the present invention can adhere a semiconductor chip to a support strongly.
