Abstract: Organometallic precursors are described for the formation of high resolution lithography patterning coatings based on metal oxide hydroxide chemistry. The precursor compositions generally comprise ligands readily hydrolysable by water vapor or other OH source composition under modest conditions. The organometallic precursors generally comprise a radiation sensitive organo ligand to tin that can result in a coating that can be effective for high resolution patterning at relatively low radiation doses and is particularly useful for EUV patterning. The precursors compositions are readily processable under commercially suitable conditions. Solution phase processing with in situ hydrolysis or vapor based deposition can be used to form the coatings.

Abstract: Apparatuses and methods are described for removing edge bead on a wafer associated with a resist coating comprising a metal containing resist compositions. The methods can comprise applying a first bead edge rinse solution along a wafer edge following spin coating of the wafer with the metal based resist composition, wherein the edge bead solution comprises an organic solvent and an additive comprising a carboxylic acid, an inorganic fluorinated acid, a tetraalkylammonium compound, or a mixture thereof. Alternatively or additionally, the methods can comprise applying a protective composition to the wafer prior to performing an edge bead rinse. The protective composition can be a sacrificial material or an anti-adhesion material and can be applied only to the wafer edge or across the entire wafer in the case of the protective composition. Corresponding apparatuses for processing the wafers using these methods are presented.

Abstract: Organometallic solutions have been found to provide high resolution radiation based patterning using thin coatings. The patterning can involve irradiation of the coated surface with a selected pattern and developing the pattern with a developing agent to form the developed image. The patternable coatings may be susceptible to positive-tone patterning or negative-tone patterning based on the use of an organic developing agent or an aqueous acid or base developing agent. The radiation sensitive coatings can comprise a metal oxo/hydroxo network with organic ligands. A precursor solution can comprise an organic liquid and metal polynuclear oxo-hydroxo cations with organic ligands having metal carbon bonds and/or metal carboxylate bonds.

Abstract: As described herein, photosensitive composition comprises RSnL3, where R is a hydrocarbyl ligand with 1-20 carbon atoms and one or more silicon and/or germanium heteroatoms and L is an acetylide ligand (—C≡CA, where A is a silyl group with 0 to 6 carbon atoms or an organo group with 1 to 10 carbon atoms). Methods are described wherein photosensitive compositions are synthesized by reacting RX, where X is a halide, and MSnL3, where M is an alkali metal, alkali earth metal or a pseudo-alkali earth metal, L is an acetylide or a dialkylamide. The radiation sensitive compositions are effective for radiation based patterning, such as with EUV light.

Abstract: Patterning compositions are described based on organo tin dodecamers with hydrocarbyl ligands, oxo ligands, hydroxo ligands and carboxylato ligands. Alternative dodecamer embodiments have organo tin ligands in place of hydrocarbyl ligands. The organo tin ligands can be incorporated into the dodecamers from a monomer with the structure (RCC)3SnQ, where R is a hydrocarbyl group and Q is a alkyl tin moiety with a carbon bonded to the Sn atom of the monomer and with a Sn bonded as a replacement of a quaternary carbon atom with bonds to 4 carbon atoms. Some or all of the carboxylato and hydroxyl ligands can be replaced with fluoride ions. Good EUV patterning results are obtained with the dodecamer based patterning compositions.

Abstract: Organometallic radiation resist compositions are described based on tin ions with alkyl ligands. Some of the compositions have branched alkyl ligands to provide for improved patterning contrast while maintaining a high degree of solution stability. Blends of compounds with distinct alkyl ligands can provide further improvement in the patterning. High resolution patterning with a half-pitch of no more than 25 nm can be achieved with a line width roughness of no more than about 4.5 nm. Synthesis techniques have been developed that allow for the formation of alkyl tin oxide hydroxide compositions with very low metal contamination.
