  • Patent number: 8975632
    Abstract: Semiconductor elements deteriorate or are destroyed due to electrostatic discharge damage. The present invention provides a semiconductor device in which a protecting means is formed in each pixel. The protecting means is provided with one or a plurality of elements selected from the group consisting of resistor elements, capacitor elements, and rectifying elements. Sudden changes in the electric potential of a source electrode or a drain electrode of a transistor due to electric charge that builds up in a pixel electrode is relieved by disposing the protecting means between the pixel electrode of the light-emitting element and the source electrode or the drain electrode of the transistor. Deterioration or destruction of the semiconductor element due to electrostatic discharge damage is thus prevented.

Silicide (e.g., cobalt silicide (CoSi2)) structures, which are utilized to form source and drain metal-to-silicon contacts in the FET, are used to form the Schottky barrier and backside Ohmic contact of the Schottky diode. Heavily doped drain (HDD) diffusions and lightly doped drain (LDD) diffusions, which are used to form source and drain diffusions of the FET, are utilized to form a suitable contact diffusion under the backside contact silicide.
