发明名称 Composition and methods for forming metal films on semiconductor substrates using supercritical solvents
摘要 Compositions and methods for forming metal films on semiconductor substrates are disclosed. One of the disclosed methods comprises: heating the semiconductor substrate to obtain a heated semiconductor substrate; exposing the heated semiconductor substrate to a composition containing at least one metal precursor comprising at least one ligand, an excess amount of neutral labile ligands, a supercritical solvent, and optionally at least one source of B, C, N, Si, P, and mixtures thereof; exposing the composition to a reducing agent and/or thermal energy at or near the heated semiconductor substrate; disassociating the at least one ligand from the metal precursor; and forming the metal film while minimizing formation of metal oxides.
