Abstract:
A solid state image sensing device employing a frame transfer system, the device comprising:a semiconductor substrate;a plurality of isolation regions extending in one direction on said semiconductor substrate, said isolation regions extending generally parallel to each other with a given spacing therebetween;a plurality of channel regions disposed on said semiconductor substrate between adjacent said isolation regions, at least one of said plurality of channel regions contacting more than one of said plurality of isolation regions;a plurality of transfer electrodes extending parallel to each other in a direction to intersect with said plurality of channel regions above said semiconductor substrate; anda plurality of power supply lines directly connected to said plurality of transfer electrodes and extending along and over said plurality of isolation regions but not over said plurality of channel regions, wherein each of said power supply lines includes a poly-silicon layer directly connected to the transfer electrodes and one of a refractory metal layer and a silicide layer, which are formed on the poly-silicon layer, and wherein the silicide layer is formed by a refractory metal combined with silicon.
