    摘要： A method of manufacturing a surface shape recognition sensor. A sacrificial film is formed on an interlevel dielectric to cover a lower electrode while keeping an upper portion of a support electrode exposed. An upper electrode is formed on the sacrificial film and support electrode. The sacrificial film is selectively removed and a protective film is formed on the upper electrode. A photosensitive resin film having photosensitivity is formed on the protective film. A plurality of projections are formed in a region of the protective film above a capacitive detection element. In this manner a plurality of capacitive detection elements each having the lower electrode and upper electrode are formed.

    摘要： A surface shape recognition sensor includes capacitive detection elements, support electrode, protective film, and projections. The detection elements are formed from lower electrodes and a deformable plate-like upper electrode made of a metal. The lower electrodes are insulated and isolated from each other and stationarily laid out on a single plane of an interlevel dielectric formed on a semiconductor substrate. The upper electrode is laid out above the lower electrodes at a predetermined interval and has opening portions. The support electrode is laid out around the lower electrodes while being insulated and isolated from the lower electrodes, and formed to be higher than the lower electrodes to support the upper electrode. The protective film is formed on the upper electrode to close the opening portions. The projections per one pixel are laid out in a region of the protective film above the capacitive detection element.

    摘要： A small shape recognizing capacitive sensor device includes detection elements, sensor circuits, and a correction circuit. The detection elements are arranged adjacent to each other. The sensor circuits are connected to the detection elements, respectively. The correction circuit corrects the output signal level of the sensor circuit. The output signal level correction circuit includes a calibration circuit, calibration reference signal generation circuit, and comparison circuit. The calibration circuit is connected to the output side of the sensor circuit. The calibration reference signal generation circuit generates a calibration reference signal. The comparison circuit compares the output from the sensor circuit with the calibration reference signal and supplies the difference output to the calibration circuit as a control signal. The calibration circuit corrects the level of the sensor circuit output on the basis of the control signal such that the difference between the output from the sensor circuit and the calibration reference signal becomes zero.

    摘要： A response signal generating unit (3) applies a predetermined supply signal (2S) to a detection element (1) and outputs, as a response signal (3S), a signal which has changed in accordance with the impedance of an object (10) with which the unit is in contact through the detection element (1). A waveform information detection unit (4) detects waveform information corresponding to the impedance of the object (10) on the basis of the response signal (3S) from the response signal generating unit (3), and outputs a detection signal (4S) representing the waveform information. A biometric recognition unit (5) determines on the basis of the detection signal (4S) from the waveform information detection unit (4) whether or not the object (10) is a living body.

    摘要： A first control potential setting means (1) generates a first control potential (N2) which reverses the magnitude relationship with a second control potential (N3) when an input signal (IN) reaches the vicinity of a logical threshold value. A second control potential setting means (2) generates the second control potential (N3) which changes in the same direction as the input signal (IN), in accordance with a change in input signal (IN). An output means (3) includes transistors (Q5, Q6), and generates an output signal (OUT) having a predetermined potential on the basis of the first control potential (N2), the second control potential (N3), and a reset signal (RSET). A reset means (4) turns off the transistor (Q6) while a waveform shaping circuit is in operation.
