Abstract: PURPOSE:To prevent erroneous operation of an integrated circuit due to strong light irradiation by providing a light transmitting cap with a cover. CONSTITUTION:When a light is irradiated in the state that a voltage is reversely applied to pn junction, a leakage current is flown to erroneously operate the integrated circuit. Black plastic liquid is coated on the surface of a cap or chip of black plastic to form a cover for shielding light. Then, even if strong light is incident to the integrated circuit, the leakage current will not flow through the pn junction in the integrated circuit due to light energy, but the integrated circuit is normally operated.
