Patent ID: 6864184

Claim:
An A semiconductor device processing method, comprising the steps of: (a) using a patterned photoresist to form a structure having at least one edge; (b) prior to removal of the photoresist, forming a conforming layer from an organic compound and patterning the conforming layer to form at least one sidewall spacer which is self-aligned to the at least one edge; (c) performing a processing operation which is at least partially localized by the at least one sidewall spacer; and (d) removing the at least one sidewall spacer and the photoresist wherein the conforming layer is formed via deposition of at least one organic compound selected from C 1 to C 8 alkanes, C 2 to C 8 alkanes, C 3 to C 8 cyclo-alkanes, C 4 to C 8 cyclo-alkenes, C 1 to C 8 fluoro-alkanes, C 2 to C 8 fluoro-alkenes, C 4 to C 8 cyclofluoro-alkanes C 4 to C 8 cyclofluoro-alkenes, or mixtures thereof, wherein in the patterning the conforming layer to form at least one sidewall spacer, the patterning anisotropically removes substantially all of the conforming layer from surfaces other than the at least one edge.
