Claim:
1. A method comprising: forming a first dielectric layer having an opening over a first metal layer; forming a first electrode layer over the first dielectric layer and the first metal layer; forming a resistive layer over the first electrode layer; forming a second electrode layer over the resistive layer; forming a third dielectric layer over the second electrode layer; patterning the second electrode layer to form a first lip portion that extends laterally over the resistive layer by a first distance beyond a region defined by the opening, wherein patterning the second electrode layer to form the first lip portion further includes patterning the third dielectric layer to form the first lip portion; patterning the resistive layer and the first electrode layer to form a second lip portion that extends laterally over the first dielectric layer by a second distance beyond the region defined by the opening, the second distance being different than the first distance; forming a second dielectric layer over the patterned second electrode layer; forming a trench extending through the second dielectric layer to the patterned second electrode layer; and forming a conductive material within the trench.
