Abstract
A semiconductor device includes a transistor. The transistor includes an active region in a substrate, a patterned conductive layer being a portion of an interconnection layer for routing, and an insulating layer extending over the substrate and configured to insulate the active region from the patterned conductive layer. The patterned conductive layer and the insulating layer serve as a gate of the transistor.

A method, comprising:
- providing a substrate;
- defining a first active region and a second active region in the substrate;
- forming a second gate on the substrate, the second gate and the second active region defining a second transistor;
- and
- forming an insulating layer covering the second gate, the second active region and the first active region, the insulating layer serving as a component of a first gate of a first transistor, the first transistor associated with the first active region.
