    摘要: There is provided a physical sensor which ensures long-term reliability and can be miniaturized and increased in density, and a method of producing the same. A physical sensor includes a supporting substrate, an element substrate that includes a sensor element and is joined to the supporting substrate through an insulating layer, a glass cap that covers an area of the sensor element and is joined to the element substrate, and a built-in electrode that is electrically connected to the sensor element. The built-in electrode is formed in a through hole passing through the element substrate, the insulating layer and the supporting substrate. A portion of the glass cap that covers an area of the built-in electrode is anodically bonded to the element substrate.

    摘要: A technique capable of integrally forming SMR type acoustic wave filters corresponding to multiple bands on the same chip at low cost is provided. In SMR type acoustic wave filters including multiple bandpass filters corresponding to multiple bands formed over the same die (substrate), acoustic multilayer films are formed without or with a minimum number of masks and piezoelectric thin films having different thicknesses for respective bands are collectively formed. For example, after the acoustic multilayer films (low acoustic impedance layers and high acoustic impedance layers) are formed in a deep groove in a terrace paddy field shape over the die in a maskless manner, the piezoelectric thin films are c-axis-oriented and grown, and are polished by CMP method or the like to be adjusted in a thickness for respective bands, and therefore, the SMR type acoustic wave filters for multiple bands are formed over the same chip.

    摘要: Control electrode wirings which are led out from control electrodes over a number of chips built in a flat package and insulating members which are provided in order to insulate the control electrode wirings from main electrode wirings are also given function of positioning of the respective semiconductor chips in the flat package. Further, a one-piece control electrode wiring net is housed in the common electrodes of the package and the electrodes which are led out from the control electrodes of the respective semiconductor chips are connected to the net to simplify the processing of a large number of gate signal wirings.
