A first electrode is formed on the major surface of a semiconductor substrate and comprises a first Al connection layer formed over the semiconductor substrate and a barrier metal layer provided on, and electrically connected to, the first Al connection layer and serving as a barrier against the Al. An insulating film is formed over the semiconductor substrate so as to cover the first electrode. An opening is formed in the insulating film so as to partially expose the first electrode. An antifuse film is formed in a manner to partially cover the insulating film and contact with the barrier metal layer of the first electrode with the opening therebetween. The antifuse film is formed of silicon nitride whose nitrogen/silicon atomic composition ratio ranges from 0.6 to 1.2. A second electrode is formed over the antifuse film and comprised of a barrier metal layer serving as a barrier against the Al.

    摘要: A method of screening a semiconductor device. A silicon wafer having gate electrodes formed on the gate oxide film is prepared. An insulating layer is deposited on the silicon wafer. Gate electrode portions of a group of transistors to be tested are exposed. A conductive layer is deposited on the silicon wafer having exposed gate electrodes. The conductive layer is patterned to be a wiring layer so that the gate electrodes of a group of the transistors can be electrically connected to each other. The chip area to be tested is irradiated with light having intensity enough to generate a required quantity of carriers in a depletion layer between a well and a substrate. A predetermined test voltage is applied between the wiring layer and the substrate of the silicon wafer during irradiation of the light to measure current flowing through the wiring layer and the gate oxide film. An abnormality of the gate oxide film can be detected on the basis of the measured current value. The screening method may be conducted before the completion of forming the gate electrodes. Further, gate electrode portions not to be used by a user may not be electrically connected to the gate electrode portions to be used.
