The deposition and dissociation of the precursor cyclooctadiene-copper
(I)-hexafluoroacetylacetonate [(COD)Cu(hfac)] on Si(111)-7 X 7 was stu
died by XPS at various temperatures. COD is desorbed by similar to 233
K and the decomposition of the hfac ligand occurs by a temperature of
383 K, probably with migration of CFx groups to the Si surface. These
further decompose above 383 K and all F signals are lost by 983 K. On
ly C and O remain detectable on the surface above 983 K, the former pr
obably as carbide. (C) 1998 Elsevier Science B.V.
