    Abstract: Radiation-sensitive sol-gel compositions are provided, along with methods of forming microelectronic structures and the structures thus formed. The compositions comprise a sol-gel compound and a base generator dispersed or dissolved in a solvent system. The sol-gel compound comprises recurring monomeric units comprising silicon with crosslinkable moieties bonded to the silicon. Upon exposure to radiation, the base generator generates a strong base, which crosslinks the sol-gel compound in the compositions to yield a crosslinked layer that is insoluble in developers or solvents. The unexposed portions of the layer can be removed to yield a patterned sol-gel layer. The invention can be used to form patterns from sol-gel materials comprising features having feature sizes of less than about 1 m.

    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.
