Method of fabricating a metal wiring line

摘要

A method of fabricating a metal wiring line includes providing a semiconductor substrate having a region desired for connecting with the metal wiring line, wherein a first dielectric layer is formed to cover the semiconductor substrate and a plurality of substantially parallel oxide pillars are formed on the first dielectric layer. The metal wiring line is then formed to contact the desired connecting region, and a second metal layer is then formed to contact the metal wiring line.
