Abstract
A method of forming a semiconductor structure includes forming a first conductive contact in a first dielectric layer coupled to a first device and forming a second conductive contact in the first dielectric layer coupled to a second device. A first trench is formed in the first dielectric layer having a first depth and exposing at least a portion of the first conductive contact. A second trench is formed in the first dielectric layer having a second depth different than the first depth and exposing at least a portion of the second conductive contact. A first conductive layer is formed in the first trench and the second trench. A second dielectric layer is formed in the first trench and the second trench over the first conductive layer.
