| Zusammenfassung: | Provided is a semiconductor device having a substrate, a semiconductor chip flip-chip mounted on the substrate, and a stacked film provided in a gap between the substrate and the semiconductor chip. The stacked film is composed of a protective film covering the surface of the substrate, and an underfill film formed between the solder resist film and the semiconductor chip. The protective film is roughened on the contact surface brought into contacting said underfill film. |
