Abstract
A method for making a semiconductor device is described. That method includes forming a sacrificial layer on a substrate, then forming a layer of photoresist on the sacrificial layer. After the photoresist layer is patterned, to form a patterned photoresist layer that has a first opening, part of the sacrificial layer is removed to generate an etched sacrificial layer that has a second opening that is substantially smaller than the first opening.
