Abstract

Various methods include: forming an opening in a resist layer to expose a portion of an underlying blocking layer; performing an etch on the exposed portion of the blocking layer to expose a portion of an etch stop layer, wherein the etch stop layer resists etching during the etch of the exposed portion of the blocking layer; etching the exposed portion of the etch stop layer to expose a portion of a substrate below the exposed portion of the etch stop layer and leave a remaining portion of the etch stop layer; and ion implanting the exposed portion of the substrate, wherein the blocking layer prevents ion implanting of the substrate outside of the exposed portion.
