Patent ID: 8771828

Claim:
A semiconductor device comprising a circuit substrate and a semiconductor element on the circuit substrate, wherein the semiconductor element comprises protruded electrodes sealed with a sealing film, wherein the sealing film comprises a resin layer containing the following (A), (B) and (C) and having a flow within the range of 150 to 1800 μm at 80° C.: (A) a resin component containing (a1) a high-molecular-weight component comprising crosslinking functional groups and having a weight-average molecular weight of 100,000 or more and a Tg within the range of −50 to 50° C. and (a2) a thermosetting component comprising an epoxy resin as a main component, (B) a filler having an average particle size within the range of 1 to 30 μm, and (C) a colorant, and wherein the sealing film contains 1 to 300 parts by mass of the filler (B) and 0.01 to 10 parts by mass of the colorant (C), based on 10 parts by mass of the resin component (A) containing 5 to 85% by mass of the high-molecular-weight component (a1) and 15 to 95% by mass of the thermosetting component (a2).
