Abstract
A method of manufacturing a semiconductor device includes forming a hard mask layer over a substrate and activating a surface of the hard mask layer to form a surface active layer over the hard mask layer. A resist layer is formed over the hard mask layer and a metal-containing layer is selectively formed over the surface active layer in at least one trench defined between portions of the resist layer. The resist layer is removed to define a pattern between portions of the selectively formed metal-containing layer and the hard mask layer is etched in accordance with the pattern. The etched pattern is transferred to at least a portion of the substrate and at least a portion of the hard mask layer, surface active layer, and metal-containing layer are removed.
