Abstract
A technique of patterning a conductive layer for interconnections in integrated circuits is disclosed. The technique enables fine line conductors to be fabricated. In accordance with the invention, a pattern for the conductors is etched into the surface of a substrate through the use of a patterned photoresist layer. The conductive layer is then deposited over the photoresist layer and into the pattern etched into the substrate surface. In intervening steps, only the portions of the conductive layer outside the depression of the pattern in the surface are removed; the portions of the conductive layer within the depression remains intact to provide the pattern of fine line conductors desired.
