    摘要: A semiconductor device includes, on a protective film laminated on a circuit principal part, (i) a light blocking film provided so as to cover the circuit principal part, (ii) an aluminum oxide film provided so as to completely cover the light blocking film, and (iii) a light-blocking upper wiring provided on the aluminum oxide film. An attempt to exfoliate the light blocking film or the light blocking upper wiring causes the resistance-detection-use upper wiring to break or thin, thereby resulting in an increase in the resistance of the resistance-detection-use wiring. The increase in the resistance is detected by the resistance detecting circuit part, and malfunction or inoperativeness of the circuit principal part is caused in response of detection. By so doing, the circuit principal part can be protected from analysis.

    摘要: After a field oxide film is formed on a P-type semiconductor substrate, ion implantation of boron is carried out with respect to a whole surface of the substrate so that a channel stopper layer is formed. Then, a MOS FET is formed in an active region of the semiconductor substrate. Subsequently, ion implantation of phosphorus is carried out, by using a gate electrode of the MOS FET and the field oxide film as a mask, so that impurity layers which have the same type of conductivity as that of the channel stopper layer and has a concentration lower than that of the channel stopper layer are formed right under the source/drain regions of the MOS FET between the source/drain regions and the channel stopper layer.
