Semiconductor device with silicone ladder resin film

摘要

A semiconductor device has a stress-buffering film which is effective in buffering the stress caused by a moulding resin during sealing. The stress-buffering film is made of a silicone ladder resin represented by formula (I) in which each end group R may be the same or different and represents an alkyl group, each side chain R' may be the same or different and represents a cyclohexyl group, a lower alkyl group, or a photopolymerisable unsaturated group, and n is an integer of 10 or larger.
