摘要:
The present invention relates to novel, soluble, multi-ligand-substituted metal oxide compounds to form metal oxide films with improved stability as well as compositions made from them and methods of their use. Specifically, the invention pertains to compounds having the following structure (I) wherein M is a metal and n is 1 to 20, and wherein at least one of R1, R2, R3, and R4 is i) and at least at least one of R1, R2, R3, and R4 is ii), where i) is a silicon bearing organic moiety having at least 2 carbons, and ii) is an organic moiety. The invention also relates to spin-coatable compositions of compounds of structure (I) dissolved into a solvent. The present invention further relates to processes using this spin coatable composition to form a coating on a patterned substrate.
