Zusammenfassung:	Circuits employing a back side-front side connection structure for coupling back side routing to front side routing, and related complementary metal oxide semiconductor (CMOS) circuits and methods are disclosed. The circuit includes a front side metal line disposed adjacent to a front side of a semiconductor device for providing front side signal routing. The circuit also includes a back side metal line disposed adjacent to a back side of the semiconductor device for providing back side signal routing. In this manner, the back side area of the semiconductor device may be employed for signal routing to conserve area and/or reduce routing complexity. The circuit also includes a back side-front side connection structure that electrically couples the front side metal line to the back side metal line to support signal routing from the back side to the front side of the circuit, or vice versa to provide greater routing flexibility.
