Abstract:
An integrated circuit includes a front-side horizontal conducting line in a first metal layer, a front-side vertical conducting line in a second metal layer, a front-side fuse element, and a backside conducting line. The front-side horizontal conducting line is directly connected to the drain terminal-conductor of a transistor through a front-side terminal via-connector. The front-side vertical conducting line is directly connected to the front-side horizontal conducting line through a front-side metal-to-metal via-connector. The front-side fuse element having a first fuse terminal conductively connected to the front-side vertical conducting line. The backside conducting line is directly connected to the source terminal-conductor of the transistor through a backside terminal via-connector.
