Abstract:
Provided is a versatile heat-curable resin composition for semiconductor encapsulation that has a favorable water resistance and abradability, and exhibits a superior fluidity and a small degree of warpage even when used to perform encapsulation on a large-size wafer. The heat-curable resin composition of the invention contains: (A) a cyanate ester compound having not less than two cyanato groups in one molecule; (B) a phenol curing agent containing a resorcinol-type phenolic resin; (C) a curing accelerator; and (D) a spherical inorganic filler.

Claim (Index 1):
A heat-curable resin composition for semiconductor encapsulation, comprising:\n (A) a cyanate ester compound having not less than two cyanato groups in one molecule, said cyanate ester compound containing a cyanate ester compound (A-1) represented by the following formula (1) and exhibiting a viscosity of not higher than 50 Pa\u00b7s when measured by a B-type rotary viscometer at 23\u00b0 C. in accordance with a method described in JIS K7117-1:1999 wherein n represents an integer of 0 or 1; each of R 1  and R 2  represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and R 3  represents a divalent linking group selected from the groups expressed by the following formulae (2) to (5) (B) a phenol curing agent containing a resorcinol-type phenolic resin represented by the following formula (6) wherein n represents an integer of 0 to 10; each of R 1  and R 2  independently represents a hydrogen atom or a monovalent group selected from the group consisting of an alkyl group having 1 to 10 carbon atoms, an allyl group and a vinyl group; (C) a curing accelerator; and (D) an inorganic filler that is spherical, has an average particle diameter of 1 to 20 \u03bcm when measured by a laser diffraction method, has been surface-treated with a silane coupling agent represented by the following formula (7) and is added in an amount of 1,200 to 2,200 parts by mass with respect to 100 parts by mass of a sum total of said components (A) and (B)\n R a 1 (OR 2 ) (3-a) Si\u2014C 3 H 6 \u2014R 3  \u2003\u2003(7) \n wherein a represents an integer of 0 to 3; R 1  represents a methyl group or an ethyl group; R 2  represents an alkyl group having 1 to 3 carbon atoms; and R 3  represents a group selected from the group consisting of the nitrogen-containing functional groups represented by the following formulae (8) to (11).
