Abstract: A magnetic detection device of which an output can be completely switched over with an external magnetic field is formed in a small size. A detection circuit is formed by forming circuit elements such as an active element layer and interconnection layers on a substrate. An insulating layer is formed on the detection circuit, and a flat surface is formed on the resultant surface. A magnetic detection element that detects an external magnetic field by using a magneto-resistance effect and a fixed resistance element, which has the same electric resistance as the magnetic detection element but does not react to the external magnetic field, are formed on the flat surface. Electrode layers and a lead layer are formed on the flat surface, and the lead layer and the interconnection layer are electrically connected to each other via a bump penetrating the insulating layer. The magnetic detection element and the fixed resistance element are formed on the flat surface of the insulating layer, thereby forming a small magnetic detection device.

Abstract: A manufacturing method of a thin film magnetic head is provided. In the manufacturing method of a thin film magnetic head, an inorganic insulating layer is formed along at least a sidewall surface of each conductor part. A gap of each conductor part is filled by an organic insulating layer. An upper surface of the conductor part, a magnetic pole portion, and a connecting layer are grinded to be planar with an organic insulating layer and an inorganic insulating layer. During an upper surface of each conductor part is grinded, the inorganic insulating layer, which is hard, suppresses a shear drop of each conductor part by grinding.

Abstract: In a magnetic detection device using a magnetic resistance element, the resistance of a layer having a multi-layer structure can be easily adjusted without causing damages to the layer. A magneto-resistance layer is connected in series to a reference resistance layer, and a magneto-resistance layer is connected in series to a reference resistance layer on a substrate. A voltage is applied between a power supply layer and a grounding layer. A first output conductive layer and the reference resistance layer extend in parallel to each other so that they are partially electrically connected to each other via a connection layer. A second output conductive layer and the reference resistance layer extend in parallel to each other so that they are partially electrically connected to each other via a connection layer. Accordingly, it is possible to adjust the resistance of the reference resistance layers by selecting the respective positions of the connection layers.

Abstract: A sensor substrate includes a plurality of piezoresistance elements. The electrical resistance of each piezoresistance element changes in accordance with an amount of displacement of a displacement portion displaced by an external load applied through a pressure receiving unit. A base substrate supports the sensor substrate. The sensor substrate and the base substrate each include a support supporting the displacement portion such that the displacement portion can be displaced and a plurality of electrically connecting portions electrically connected to the plurality of piezoresistance elements. The supports of the sensor and base substrates are joined to each other and the plurality of electrically connecting portions of the sensor and base substrates are joined to each other. Furthermore, in each of the sensor and base substrates, either the support or the plurality of electrically connecting portions or both extend to the periphery of the sensor substrate or the base substrate.

Abstract: A lower shield layer is formed by being embedded in a first recess formed in an under layer. Accordingly, the distance between the lower shield layer and a slider can be reduced. Also, a second metal layer is formed from above a gap layer covering an electrode extracting layer over above the under layer hindwards therefrom. Accordingly, the second metal layer can be brought closer to the slider side than an upper shield layer. Consequently, the thermal dissipation effects of the thin-film magnetic head can be improved.
