Abstract

A method for providing at least one contact on a semiconductor is disclosed. The semiconductor includes a plurality of isolation structures. The method and system include providing an etch-stop layer in direct contact with the semiconductor, providing a dielectric layer over the etch-stop layer, and etching through the dielectric layer and a portion of the etch-stop layer. A portion of the semiconductor in proximity with one of the plurality of isolation structures is not exposed during the etch.
