Semiconductor device comprising a semiconductor substrate, an element formed thereon, and a stress-buffering film made of a silicone ladder resin

摘要

A semiconductor device having a stress-buffering film which is effective in buffering the stress caused by a molding resin during sealing, the stress-buffering film being made of a silicone ladder resin represented by formula (I) <IMAGE> (I) wherein each end group R may be the same or different and represents a hydrogen atom or an alkyl group, each side chain R' may be the same or different and represents a cyclohexyl group, a lower alkyl group, or a photopolymerizable unsaturated group, and n is an integer of 10 or larger.
