Abstract:
1. A semiconductor device comprising a semiconductor integrated circuit and a printed wiring board on which the semiconductor integrated circuit is mounted, wherein the semiconductor integrated circuit has a first electrode and a second electrode to get power supply from the printed wiring board, wherein the first electrode and the second electrode are adjacently arranged, wherein a decoupling capacitor is mounted on the printed wiring board, wherein the decoupling capacitor has a first terminal and a second terminal, wherein the first electrode and the first terminal are connected by a first metal electrode plate, wherein the second electrode and the second terminal are connected by a second metal electrode plate, and wherein a dielectric film is interposed between the first metal electrode plate and the second metal electrode plate, wherein the first and second metal electrode plates interposing the dielectric film therebetween are fabricated as a wiring part in another process than that of the printed wiring board, and wherein the wiring part is fixed to the printed wiring board by soldering, wherein the first metal electrode plate is formed of a first epitaxial electrode film, wherein the dielectric film is formed of an epitaxial dielectric film stacked on the first epitaxial film, wherein the second metal electrode plate is formed of a second epitaxial electrode film stacked on the dielectric film, and wherein a constituent material of the epitaxial dielectric film has a perovskite structure.
