The precursor composition may contain a solvent medium, so that the composition is adapted for liquid delivery CVD, to form stable thin-film gate dielectrics for fabrication of microelectronic devices.Type: GrantFiled: October 7, 1999Date of Patent: June 4, 2002Assignee: Advanced Technology Materials Inc.Inventors: Thomas H.
