摘要:
A vapor deposition process for depositing a germanium material on a substrate by volatilizing a germanium amidinate precursor to form a germanium-containing precursor vapor and depositing said germanium material on the substrate. The precursor is preferably germanium bis(n-butyl, N,N-diisopropylamidinate). The process and the precursors of the invention are useful for forming germanium-antimony-tellurium (GST) films and microelectronic device products, such as phase change memory devices, including such films.
摘要:
Germanium, tellurium, and/or antimony precursors are usefully employed to form germanium-, tellurium- and/or antimony-containing films, such as films of GeTe, GST, and thermoelectric germanium-containing films. Processes for using these precursors to form amorphous films are also described. Further described is the use of [{nBuC(iPrN) 2 } 2 Ge] or Ge butyl amidinate to form GeTe smooth amorphous films for phase change memory applications.
