ABSTRACT:
A semiconductor device where an aluminum electrode surrounds an output electrode of an element, is provide by a detector electrode formed on a ring shaped space between the output electrode and the aluminum electrode. Sliding of the aluminum electrode toward the output electrode which occurs in an aging degradation, is detected by contact between the aluminum electrode and the detector electrode.
