PROCESS FOR PREPARING ORGANOTIN COMPOUNDS
Last updated:
Abstract:
Provided is a facile process for preparing certain organotin compounds having alkyl and alkylamino substituents. The process provides organotin precursor compounds, for example tris(dimethylamido)isopropyl tin, in a highly pure form. As such, the products of the process are particularly useful in the deposition of high-purity tin oxide films in, for example, extreme ultraviolet light (EUV) lithography techniques used in microelectronic device manufacturing.
