摘要: A surface shape recognition apparatus includes a plurality of sensor electrodes, passivation film, capacitance detection circuit, and ground electrode. The sensor electrodes are formed on an interlevel insulator on a substrate and insulated from each other. The passivation film is formed on the interlevel insulator to cover the upper and side surfaces of each sensor electrode. The passivation film is formed from a dielectric material. When a target recognition object comes into contact with the surface of the passivation film, the capacitance detection circuit detects an electrostatic capacitance formed between the sensor electrode and the surface of the target recognition object opposing the sensor electrode. The ground electrode passes static electricity on the surface of the passivation film.

摘要: A structure (113b) which includes an overhang and a support portion supporting substantially the center of the overhang, and in which the area of the support portion is smaller than the area of the overhang in the two-dimensional direction of an upper electrode (1110b) is formed on the upper electrode (110a) in a region above each lower electrode 105a in one-to-one correspondence with the lower electrode (105a). An object of surface shape sensing, e.g., the tip of a finger (1602) touches the surface of the overhang of the structure (113b), and the support portion of the structure (113b) whose overhang is in contact with the object of sensing pushes down a portion of the upper electrode (110a) toward the lower electrode (105a), thereby deforming the upper electrode (110a).

摘要: A surface shape recognition apparatus includes detection circuit, comparison circuit, storage circuit, and control circuit. The detection circuit electrically detects a surface shape pattern in a partial region of the target collation surface of an object using a plurality of sensor elements and outputs detection data representing the surface shape pattern. The comparison circuit compares the detection data from the detection circuit with predetermined collation data and outputs a comparison result. The storage circuit stores template data representing the surface shape pattern of the entire target collation surface, the template data being obtained from the object in advance. The control circuit partially reads out, as collation data, the template data stored in the storage circuit from an arbitrary position, outputs the collation data to the comparison circuit, and performs determination for authentication between the template data and the object on the basis of the comparison result from the comparison circuit. A surface shape recognition method is also disclosed.

摘要: A surface shape recognition sensor includes a plurality of capacitive detection elements, a support electrode, and a protective film. The capacitive 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 a plurality of 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 opening portions of the upper electrode are laid out in a region other than regions on a main part of the lower electrode and on the support electrode. A method of manufacturing the surface shape recognition sensor is also disclosed.

摘要: A master latch (1) is formed from a static circuit, and a slave latch (2) is formed from a dynamic circuit. The number of circuit elements can be smaller as compared to a slave latch formed from a static circuit so that the size and area of a master-slave flip-flop can be reduced. Since the master latch is formed from a static circuit, data can be held stably during the standby time by setting the master latch in a data holding state.
