Abstract
The electrical fuse includes a cathode pad, an anode pad and a fuse link connecting the cathode pad to the anode pad. The cathode pad includes a group of multiple electrical contacts and a solitary electrical contact disposed a predetermined distance from the group and near the fuse link, i.e., between the group of multiple electrical contacts and the fuse link. The cathode and anode pads as well as the fuse link include a polysilicon layer and a silicide layer.
