    Abstract: The present invention relates to an anti-reflective coating composition characterized by comprising a resin made from triazine compounds having at least two nitrogen atoms substituted a hydroxymethyl group and/or alkoxymehyl group, and a light absorbing compound and/or a light absorbing resin. The present invention offers an anti-reflective coating composition for the anti-reflective coating having high light absorption property of the light used for the lithography process in the preparation of semiconductor device, showing high reflective light preventing effect, being used at thinner film thickness more than before, and having greater dry etching rate in comparison to photoresist layer.

    Abstract: Novel double- and triple-patterning methods are provided. The methods involve applying a shrinkable composition to a patterned template structure (e.g., a structure having lines) and heating the composition. The shrinkable composition is selected to possess properties that will cause it to shrink during heating, thus forming a conformal layer over the patterned template structure. The layer is then etched to leave behind pre-spacer structures, which comprise the features from the pattern with remnants of the shrinkable composition adjacent the feature sidewalls. The features are removed, leaving behind a doubled pattern. In an alternative embodiment, an extra etch step can be carried out prior to formation of the features on the template structure, thus allowing the pattern to be tripled rather than doubled.
