    摘要： First, a stationary electrode layer is formed over a semiconductor substrate and an integrated network is composed in a circuit element area around the stationary electrode layer by electrode wiring forming each circuit element. A spacer is arranged on a passivation film in plural places. A dummy island is formed in an area between the circuit element area and the stationary electrode layer area. Supply potential Vcc is applied to the dummy island and ground potential GND is applied to a P+-type separated area.

    摘要： The sensitive coordinate input device of the present invention adopts a system in which the finger F of the operator is regarded as one electrode, and the electrostatic capacitance is varied depending on the changes in the distances between the finger and another electrode which is separated therefrom via a dielectric. Four electrodes are preferably disposed at regular angular positions. Among the four electrodes, two electrodes, and two electrodes which are located at opposite positions are spaced at intervals, respectively. Across the four electrodes, a sensitive member 15 is laid. The surface of the sensitive member is to be touched with the operator's finger F. The sensitive member is preferably formed by a dielectric having a high dielectric constant, such as a ceramic plate. According to the present invention, the area of sensitive area can easily be increased, and the determination of the cursor position on the screen of the CRT display apparatus can readily be performed.
