A process for forming an interconnect structure in a low-k dielectric layer includes etching to form trenches in the dielectric layer, removal of photoresist, and further etching to remove damaged portions of the dielectric layer in sidewalls of the trenches. An interconnect structure includes a low-k dielectric layer formed on a substrate, and a conductor embedded in the dielectric layer, the conductor having an edge portion with an inwardly rounded shape.
