Resin composition, resin film, method for producing resin film, method for producing semiconductor device, and semiconductor device

A resin composition comprising:

• (A) a silicone resin containing a constitutional unit shown by the following composition formula (1) and having a weight average molecular weight of 3,000 to 500,000,
• wherein R1 to R4 each independently represent a monovalent hydrocarbon group having 1 to 8 carbon atoms, with the proviso that the both of R3 and R4 are not methyl groups at the same time;
• “m” and “n” are each independently an integer of 0 to 300;
• the both of “a” and “b” are positive numbers satisfying a+b=1;
• each of “X” independently represents a linking group selected from the divalent groups shown by the following general formulae (2), (3), (4), and (5), and the molar numbers of units shown by said general formulae (2), (3), (4), and (5) contained in the silicone resin (A) are defined as “c”, “d”, “e”, and “f” respectively, “e” is a positive number, each of “c”, “d”, and “f” is 0 or a positive number satisfying c+d+e+f/the molar number of the linking group shown by “X” contained in the silicone resin (A)=1, and having a ratio to “e” in a range of c+d=1 to 10 and f=0 to 1 when the “e” is assumed to be 1;
• wherein “V” is a divalent organic group selected from the following
• “p” is 0 or 1, R5 represents a hydrogen atom or a methyl group, “g” is an integer of 0 to 7, R6 and R7 each independently represent the same or different group selected from alkyl groups and alkoxy groups having 1 to 4 carbon atoms, and “h” is any of 0, 1, and 2,
• wherein R8 represents a hydrogen atom or a methyl group, and “q” is an integer of 0 to 7,
• wherein “Y” is a divalent group selected from the following
• wherein “R” each independently represent a hydrogen atom or a methyl group, and R9 and R10 each independently represent a hydrogen atom or a methyl group,
• wherein R12 and R13 each independently represent a monovalent hydrocarbon group having 1 to 8 carbon atoms, with the proviso that the both of R12 and R13 are not methyl groups at the same time, “r” and “s” are each independently an integer of 0 to 300, R11 represents a hydrogen atom or a methyl group, and “k” is an integer of 0 to 7;
• (B) an epoxy resin-curing agent;
• and
• (C) a filler.
