Abstract
A semiconductor device with the metal fuse and a fabricating method thereof are provided. The metal fuse connects an electronic component (e.g., a transistor) and a existing dummy feature which is grounded. The protection of the metal fuse can be designed to start at the beginning of the metallization formation processes. The grounded dummy feature provides a path for the plasma charging to the ground during the entire back end of the line process. The metal fuse is a process level protection as opposed to the diode, which is a circuit level protection. As a process level protection, the metal fuse protects subsequently-formed circuitry. In addition, no additional active area is required for the metal fuse in the chip other than internal dummy patterns that are already implemented.
