Methods are disclosed for depositing materials selectively and
controllably from liquid, near-critical, and/or supercritical fluids to a
substrate or surface controlling the location and/or thickness of
material(s) deposited to the surface or substrate. In one exemplary
process, metals are deposited selectively filling feature patterns (e.g.,
vias) of substrates. The process can be further used to control
deposition of materials on sub-surfaces of composite or structured
silicon wafers, e.g., for the deposition of barrier films on silicon
wafer surfaces. Materials include, but are not limited to, overburden
materials, metals, non-metals, layered materials, organics, polymers, and
semiconductor materials. The instant invention finds application in such
commercial processes as semiconductor chip manufacturing. In particular,
selective deposition is envisioned to provide alternatives to, or
decrease need for, such processes as Chemical Mechanical Planarization of
silicon surfaces in semiconductor chip manufacturing due to selective
filling and/or coating of pattern features with metals deposited from
liquid, near-critical, or supercritical fluids.
