Electrical Fuse Structure and Method of Formation

摘要

A fuse device having contacts configured to reduce electro-migration is disclosed. In some exemplary embodiments, the fuse structure includes an anode disposed at a first end and a cathode disposed at a second end. A fuse link extends between and contacts the anode and the cathode. A boundary between the fuse link and the cathode has a center point, and each connector of a plurality of cathode connectors has a center point that is an equal distance from the center point of the boundary between the fuse link and the cathode. In some such embodiments, each connector of the plurality of cathode connectors is a different size than an anode connector, whereas in some such embodiments, each connector of the plurality of cathode connectors is substantially a same size as the anode connector along at least one axis.
