Abstract:
1. A semiconductor device comprising a substrate, a first semiconductor chip located over the substrate, a first heat-transmitting and electromagnetic-noise-blocking substance interposed between said first heat-transmitting and electromagnetic-noise-blocking substance serving to diffuse heat generated between said first semiconductor chip and said first heat-transmitting and electromagnetic-noise-blocking substance, and block electromagnetic noise between said first semiconductor chip and said substrate, a second semiconductor chip located over said substrate with intervention of said first semiconductor chip and the first heat-transmitting and electromagnetic-noise-blocking substance therebetween, and a second heat-transmitting and electromagnetic-noise-blocking substance that is interposed between said first and second semiconductor chips, said second heat-transmitting and electromagnetic-noise-blocking substance serving to diffuse heat generated by said second semiconductor chip and block electromagnetic noise affecting the second semiconductor chip.
