Claim 12:
13. A device comprising:
a switch structure having an input and an output, wherein the switch structure is formed in and on a silicon wafer;
a frontside metal layer formed above the silicon wafer;
a thru-silicon via, disposed beside a first diffusion region of the switch structure, wherein the thru-silicon via passes through the silicon wafer and is operably connected to a backside metal layer formed underneath the silicon wafer to a frontside metal layer formed above the silicon wafer, that couples a backside signal to a gate of the switch structure by way of the input of the switch structure; and
a frontside via that couples the output of the switch structure to an external output, wherein the frontside metal layer is used for routing the frontside via from the output of the switch structure to the external output.
