摘要： A method of manufacturing a planar inductance element, including the steps of forming a thermal oxide film, a magnetic film, a first insulating interlayer, a planar coil, and a second insulating interlayer on a first semiconductor substrate, forming an insulating film and a magnetic film on a second semiconductor substrate, and adhering the first and the second semiconductor substrates such that the coil side of the first semiconductor substrate faces the magnetic film side of the second semiconductor substrate. According to this method, a stress generated by stacking thin films can be reduced compared with that of a conventional inductance element. Therefore, a high-frequency loss can be reduced, and a quality coefficient Q can be increased.

摘要： Disclosed herein is a planar magnetic element comprising a substrate, a first magnetic layer arranged over the substrate, a first insulation layer arranged over the first magnetic layer, a planer coil formed of a conductor, having a plurality of turns, arranged over the first insulation layer and having a gap aspect ratio of at least 1, the gap aspect ratio being the ratio of the thickness of the conductor to the gap between any adjacent two of the turns, a second insulation layer arranged over the planar coil, and a second magnetic layer arranged over the second insulation layer. When used as an inductor, the planar magnetic element has a great quality coefficient Q. When used as a transformer, it has a large gain and a high voltage ratio. Since the element is small and thin, it is suitable for use in an integrated circuit, and can greatly contribute to miniaturization of electronic devices.

摘要： An amorphous magnetic thin film possesses as at least part of a thin film forming area a microstructure composed of a first amorphous phase containing at least either of iron and cobalt and bearing magnetism and a second amorphous phase disposed round the first amorphous phase and containing boron and at least one element selected from among the elements of the 4B Group in the Periodic Table of Elements and exhibits uniaxial magnetic anisotropy in the plane of film. The amorphous magnetic thin film possesses soft magnetism concurrently satisfying high saturation magnetization and high resistivity and, at the same time, easily acquires high frequency permeability by applying magnetic field in the hard axis of magnetization. Use of these amorphous magnetic thin films for plane magnetic elements permits the plane magnetic elements to be miniaturized and to be endowed with exalted performance. The amorphous magnetic thin film possesses a composition substantially represented by the formula:(Fe.sub.1-x Co.sub.x).sub.1-y (B.sub.1-z X.sub.z).sub.y(wherein X stands for at least one element selected from among the 4B Group elements and x, y, and z stand for numerals satisfying the expressions, 0
