ABSTRACT:
A widened contact area (170X) of a conductive feature (170) is formed by means of self-alignment between an edge (170E2) of the conductive feature and an edge (140E) of another feature (140). The other feature (“first feature”) is formed from a first layer, and the conductive feature is formed from a second layer overlying the first layer. The edge (170E2) of the conductive feature is shaped to provide a widened contact area. This shaping is achieved in a self-aligned manner by shaping the corresponding edge (140E) of the first feature.
