PROCESS FOR PREPARING ORGANOTIN COMPOUNDS

Abstract:

Provided is a facile methodology for preparing certain organotin compounds having alkyl and alkylamino or alkyl and alkoxy substituents. The process provides the organotin compounds in a highly pure form which are particularly useful as precursors in the deposition of high-purity tin oxide films in, for example, extreme ultraviolet light (EUV) lithography techniques used in the manufacture of certain microelectronic devices.
