PURPOSE:To reduce the erroneous operation of an integrated circuit and the like due to noise by a method wherein an insulative thin film is provided on the two electrodes which are formed in parallel with each other on the substrate and a wiring electrode is provided at the position where it overlaps with a part of the two electrodes on said insulative thin film, and a reference potential is given to one of the two electrodes. CONSTITUTION:Electrodes 7 and 8 are formed in the internal part of the substrate 3 in such a manner that the surface of the electrode is positioned within the same plane on the surface of the substrate 3, an insulative thin film 2 is formed on the electrodes 7 and 8 and the substrate 3, and a wiring electrode 1 is provided on the insulative thin film 2. Said wiring electrode 1, electrodes 7 and 8 are partially overlapped when viewed from above. Of the electrodes 7 and 8, the electrode 8 is formed equal to the reference potential. The electrodes 1, 7 and 8 constitute a transistor, electrostatic capacitance is present between the electrodes 1 and 7, and electrodes 1 and 8. A low-pass filter is formed by combining the electrostatic capacitance located between the wiring electrode s 7 and 8 and the internal resistor 4 of the wiring electrode 1, and the noise originated in amperage or voltage is reduced, thereby enabling to reduce the erroneous operation of the connected circuit 6. |
