摘要:
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.
