    Abstract: Provided are methods of trimming photoresist patterns. The methods involve coating a photoresist trimming composition over a photoresist pattern, wherein the trimming composition includes a matrix polymer, a free acid having fluorine substitution and a solvent, the trimming composition being free of cross-linking agents. The coated semiconductor substrate is heated to cause a change in polarity of the resist polymer in a surface region of the photoresist pattern. The photoresist pattern is contacted with a developing solution to remove the surface region of the photoresist pattern. The methods find particular applicability in the formation of very fine lithographic features in the manufacture of semiconductor devices.

    Abstract: Provided are methods of trimming photoresist patterns. The methods involve coating a photoresist trimming composition over a photoresist pattern, wherein the trimming composition includes a matrix polymer, a thermal acid generator and a solvent, the trimming composition being free of cross-linking agents. The coated semiconductor substrate is heated to generate an acid in the trimming composition from the thermal acid generator, thereby causing a change in polarity of the matrix polymer in a surface region of the photoresist pattern. The photoresist pattern is contacted with a developing solution to remove the surface region of the photoresist pattern. The methods find particular applicability in the formation of very fine lithographic features in the manufacture of semiconductor devices.
