Abstract
A silicide bridged anti-fuse and a method of forming the anti-fuse are disclosed. The silicide bridged anti-fuse can be formed with a tungsten plug metalization process that does not require any additional process steps. As a result, anti-fuses can be added to an electrical circuit as trim elements for no additional cost.
