Abstract
Various methods of manufacturing are disclosed. In one aspect, a method of manufacturing is provided that includes forming an anti-reflective coating on a structure on a substrate. A first spacer and a second spacer are formed adjacent to the structure. The first spacer covers a first portion of the substrate and the second spacer covers a second portion of the substrate. The anti-reflective coating is removed while the first and second spacers are left in place to protect the first and second portions of the substrate. The method provides for anti-reflective coating application and removal with reduced risk of active region damage.
