发明名称 Non-volatile semiconductor memory device with contact plug electrically conductive in response to light
摘要 Disclosed are a non-volatile semiconductor memory device capable of simplifying the complicated structure of a transistor, and a fabrication method for the same. The non-volatile semiconductor memory device includes a semiconductor substrate including a plurality of active regions, gate electrodes formed over the respective active regions of the semiconductor substrate, gate spacers formed over both sides of each of the gate electrodes, common source/drain regions formed on the surface of the semiconductor substrate at both sides of the gate electrode including the gate spacers, an interlayer dielectric formed over the whole surface of a resultant structure including the substrate, gate electrodes, gate spacers and common source/drain regions, and contact plugs penetrating the interlayer dielectric, and connecting the common source/drain regions to a data line, wherein the contact plugs are made from a material which becomes electrically conductive when in contact with light and becomes non-conductive when out of contact with light.
