Abstract: PURPOSE:To prevent the oscillation and interference of a circuit by coating one part of the upper section of a semiconductor device with an electrode material through an insulator or forming a wiring electrode to one part of the upper section of the semiconductor device. CONSTITUTION:An insulator 10 isolating wiring electrode layers is formed on terminal electrodes 101, 102, 103 for a semiconductor element, and the whole surface or one part of the semiconductor element is coated with an upper electrode 200. Consequently, the upper electrode 200 shields parasitic capacitance and mutual inductance among the terminal electrodes 101, 102, 103, thus preventing the oscillation of the element. That is, since the inter-layer insulating film 10 is shaped in size thinner than intervals among the wirings 101-103, effects by mutual indictance among the wirings are prevented by the upper electrode 200.
