METHOD OF FORMING AN INTERCONNECT STRUCTURE FOR A SEMICONDUCTOR DEVICE
摘要:
Methods of semiconductor device fabrication are provided including those that provide a substrate having a plurality of trenches disposed in a dielectric layer formed above the substrate. A via pattern including a plurality of openings may be defined above the substrate. A spacer material layer is formed on a sidewall at least one trench. Via holes can be etched in the dielectric layer using the via pattern and spacer material layer as a masking element.
