Abstract

A method includes forming a first masking layer over a substrate, the first masking layer including a first mask line and a second mask line, heating respective top surfaces of the first mask line and the second mask line with polarized light, and forming a second masking layer over the first masking layer with an area selective deposition process. The second masking layer is thinner over a sidewall of the first mask line than over a top surface of the first mask line.
