ABSTRACT:
A conducting link is disposed in an insulating layer of a semiconductor device in combination with a plurality of wirings of the device which are electrically separated from each other. The conducting link is selectively activated to provide the wirings with a conducting path, and is activatable by melting metal contained in the wirings by irradiating a portion of the wirings in the vicinity of the link with a shot of a pulse of laser beam. The link comprises a through hole or a trench disposed in the insulating layer depending on the structural configuration of the device. The method of fabricating and activating the conductive link is provided.
