LEWIS BASE ADDUCTS OF ANHYDROUS MONONUCLEAR TRIS(BETA-DIKETONATE) BISMUTH COMPOSITIONS FOR DEPOSITION OF BISMUTH-CONTAINING FILMS, AND METHOD OF MAKING THE SAME

摘要

A solvent composition useful for liquid delivery MOCVD, comprising toluene and a Lewis base, wherein toluene is present at a concentration of from about 75% to about 98% by volume, based on the total volume of toluene and the Lewis base. Such solvent composition is usefully employed to dissolve or suspend precursors therein for liquid delivery MOCVD, e.g., MOCVD of ferroelectric material films such as SBT.
