A method is disclosed for producing an array of parallel conductive lines in a first level of a multilevel interconnect structure of a semiconductor component. The lines are produced by direct etching (a conductive layer is produced), a hardmask line pattern is formed on the conductive layer and the line pattern is transferred to the conductive layer by etching the conductive layer relative to the hardmask lines. The hardmask lines are reduced in width prior to the pattern transfer. The width reduction is done at intended via locations. Local hardmask pillars are produced on the hardmask lines prior to the width reduction step, so that the original line width is maintained at the intended via locations. As a result, the width of the conductive lines obtained after the pattern transfer is smaller compared to conventional configurations, except in local areas corresponding to the locations of interconnect vias.
