  • Patent number: 10354932
    Abstract: It is an object to particularly improve compositions of interlayer insulation films so as to provide semiconductor devices which exert high elongation percentage, are excellent in adherence and are hard to generate a crack, and methods of manufacturing the devices, and a semiconductor device (1) of the present invention is a semiconductor device provided with a semiconductor element (2) and a redistribution layer (4) electrically connected to the semiconductor element, and is characterized in that a solvent with specific gravity of 0.96 g/cm3 or more at a temperature of 25° C. remains in an amount of 5 ppm or more relative to the entire weight of an interlayer insulation film (6) inside the interlayer insulation film of the redistribution layer. According to the semiconductor device of the present invention, it is possible to exert high elongation percentage, provide excellent adherence, and suppress generation of a crack.
