A semiconductor chip is mounted on a first surface of an interconnect substrate, and has a multilayer interconnect layer. A first inductor is formed over the multilayer interconnect layer, and a wiring axis direction thereof is directed in a horizontal direction to the interconnect substrate. A second inductor is formed on the multilayer interconnect layer, and a wiring axis direction thereof is directed in the horizontal direction to the interconnect substrate. The second inductor is opposite to the first inductor. A sealing resin seals at least the first surface of the interconnect substrate and the semiconductor chip. A groove is formed over the whole area of a portion that is positioned between the at least first inductor and the second inductor of a boundary surface of the multilayer interconnect layer and the sealing resin.

A method of producing a solid electrolyte (3, 13) is disclosed wherein solid electrolyte material is prepared having a composition expressed by a formula: (1-x) ZrO{xScO(where x is a number equal to or greater than 0.05 and equal to or less than 0.15), and a spark plasma method is carried out to sinter solid electrolyte material, resulting in a solid electrolyte. Such spark plasma method is executed by applying first compression load, equal to or less that 40 MPa, to solid electrolyte material, to sinter the solid electrolyte material to obtain sintered material, which is then cooled by applying second compression load, less than first compression load, to the sintered material, resulting in a solid electrolyte.

The present invention provides a composite oxide for a high performance solid oxide fuel cell which can be fired at a relatively low temperature, and which has little heterogeneous phases of impurities other than the desired composition. The composite oxide is the one having a perovskite type crystal structure containing rare earth elements, and having constituent elements homogeneously dispersed therein. A homogeneous composite oxide having an abundance ratio of heterogeneous phases of at most 0.3% by average area ratio, and a melting point of at least 1470&#xb0; C., is obtained by using metal carbonates, oxides or hydroxides, and reacting them with citric acid in an aqueous system.
