摘要： A humidity sensor package includes: a humidity sensor that is mounted on a main surface of a package substrate and that have a humidity-sensing area; a control IC that is mounted on the main surface of the package substrate; a sealing resin that seals at least an external connection portion of the humidity sensor; and a partition member that partitions a sealing area of the sealing resin and the humidity-sensing area from each other so as to expose the humidity-sensing area to an external environment. Here, a first distance in the thickness direction from the package substrate to the top surface of the partition member is smaller than a second distance in the thickness direction from the package substrate to the top surface of the sealing resin.

摘要： A thin film magnetic head includes a recording and playback element, a lead conductor layer for feeding a power to the recording and playback element, an electrically conductive bump for conductively connecting the lead conductor layer to an electrode pad for external connection, and an insulating protective layer filling between the recording and playback element and the electrically conductive bump. A thermal deformation-preventing layer composed of a material having a thermal expansion coefficient smaller than that of the insulating protective layer is disposed in the insulating protective layer in such a way as to locate between a medium-facing surface and the electrically conductive bump without being exposed at the medium-facing surface. In the resulting thin film magnetic head, protrusion of the recording and playback element toward the recording medium side can be prevented without changing the configuration of the recording and playback element nor the forming material.

摘要： In a thin-film magnetic head, an lower magnetic pole layer is formed on a lower core layer to form a step between the lower core layer and the lower magnetic pole layer. A coil layer and a coil-insulating layer are formed on the lower core layer, and an upper core layer is formed over the lower magnetic pole layer and the coil-insulating layer. This configuration decreases the height of the coil-insulating layer from the lower magnetic pole layer compared to the height in a conventional thin-film magnetic head. The front end of the upper core layer can be precisely formed so as to have a track width Tw. This thin-film magnetic head is suitable for narrower track widths.

摘要： A thin-film magnetic head is capable of securing an insulating property and minimizing the projection of a recording element section due to heat expansion. The thin-film magnetic head includes a pair of magnetic layers disposed with a predetermined gap therebetween on a surface facing a recording medium. The layers are connected to each other along an inner part in a height direction from the medium-facing surface. A spiral recording coil is disposed between the pair of magnetic layers and wound around a connecting portion of the pair of magnetic layers. The recording coil includes a dense coil portion formed with a pitch smaller than that of the inner part in the height direction so as to be closer to the medium-facing surface than the connecting portion. An organic insulating layer is locally formed to fill coil gaps of the dense coil portion, and coil gaps other than those of the dense coil portion are filled with an inorganic insulating layer.

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.

摘要： In a thin-film magnetic head, a lower magnetic pole layer and a planarizing magnetic layer in continuity with the lower magnetic layer are arranged. Since a coil formation surface is positioned lower than the top surface of the lower magnetic pole layer and the planarizing magnetic layer, the front end of an upper magnetic core layer is formed to be a predetermined track width with a high accuracy. A thin-film magnetic head having good information writing characteristics and a method for manufacturing the thin-film magnetic head are thus provided.
