  • Patent number: 10228618
    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.

  • Patent number: 8236903
    Abstract: An acid-functional polymer is reacted with a transition metal compound having an average particle size small enough to react with the polymer at a temperature below the glass transition temperature of the polymer, e.g., at room temperature, to produce cross-linked polymer. The process produces a liquid polymer product that dries to a cross-linked film without the required presence of volatile ligands. Improved coatings such as floor polishes that can be formed from these cross-linked polymers are also disclosed.
