Abstract:
A m thod of making a thin film layered superlattice material on an integrated circuit substrate using trimethylbismuth, said method comprising the steps of:dissolving said trimethylbismuth and a metal compound in a solvent to produce a final precursor liquid; forming a mist of said final precursor liquid with a carrier gas to produce a precursor mist; vaporizing said precursor mist to produce a precursor vapor; providing said integrated circuit substrate; applying said precursor vapor onto said substrate to produce said thin film superlattice material without any heating step that includes a temperature of 650Â° C. or higher; and completing the fabrication of said integrated circuit to include at least a portion of said thin film layered superlattice material in a component of said integrated circuit.
