| 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.
