Abstract :
Summary form only given. Area-selective metal-organic chemical vapor deposition (MOCVD) of gold thin films has been achieved on tungsten patterned on VLSI-type silicon wafers. Scanning Auger spectroscopy of the wafer deposition areas displays virtual exclusion of gold deposits on silicious regions with 4000-Å-thick gold films of high feature resolution covering the tungsten patterns. The films were deposited by exposing the heated wafer (T<500°C) to an ambient of (C2H5)3PAuCl vapor for 1 h
