摘要： 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.

摘要： 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.

摘要： A main magnetic pore layer is formed on an insulating layer flattened into a high-flatness surface, and a yoke layer having a large film thickness is formed under the main magnetic pole layer independently of the main magnetic pole. The main magnetic pole layer has a front end surface formed in a shape with a width size gradually increasing in a direction of track width as the front end surface departs farther away from an auxiliary magnetic pole layer. A perpendicular magnetic recording head can be provided which can suppress the occurrence of fringing in a recording pattern, and can form the main magnetic pole layer with high pattern accuracy, and can satisfactorily introduce a recording magnetic field to a fore end of the main magnetic pole layer.

摘要： 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.

摘要： 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.
