摘要:
The present invention is directed to a method of forming semiconductor devices. In one illustrative embodiment, the method comprises defining a photoresist feature having a first size in a layer of photoresist that is formed above a layer of dielectric material. The method further comprises reducing the first size of the photoresist feature to produce a reduced size photoresist feature, forming an opening in the layer of dielectric material under the reduced size photoresist feature, and forming a conductive material in the opening in the layer of dielectric material.
