    摘要: Treatment of carbon-containing low-k dielectric with UV radiation and a reducing agent enables process-induced damage repair. Also, treatment with a reducing agent and UV radiation is effective to clean a processed wafer surface by removal of metal oxide (e.g., copper oxide) and/or organic residue of CMP slurry from the planarized surface of a processed wafer with or without low-k dielectric. The methods of the invention are particularly applicable in the context of damascene processing to recover lost low-k property of a dielectric damaged during processing, either pre-metalization, post-planarization, or both, and/or provide effective post-planarization surface cleaning to improve adhesion of subsequently applied dielectric barrier and/or other layers.

    摘要: A method for the ultraviolet (UV) treatment of carbon-containing low-k dielectric enables process-induced damage repair. The method is particularly applicable in the context of damascene processing. A method provides for forming a semiconductor device by depositing a carbon-containing low-k dielectric layer on a substrate and forming a trench in the low-k dielectric layer, the trench having sidewalls ending at a bottom. The trench is then exposed to UV radiation and, optionally a gas phase source of —CH3 groups, to repair damage to the carbon-containing low-k material of the trench sidewalls and bottom caused by the trench formation process (generally etching, ashing, and wet or dry cleaning). A similar treatment, with or without the gas phase source of —CH3 groups, may be applied to repair damage caused in a subsequent planarization operation.

    摘要: An apparatus and method for the ultraviolet (UV) treatment of carbon-containing low-k dielectric enables process-induced damage repair. A semiconductor substrate processing system may be configured to include degas and plasma pre-clean modules, UV process modules, copper diffusion barrier deposition modules and copper seed deposition modules such that the substrate is held under vacuum and is not exposed to ambient air after low k damage repair and before copper barrier layer deposition. Inventive methods provide for treatment of a damaged low-k dielectric on a semiconductor substrate with UV radiation to repair processing induced damage and barrier layer deposition prior breaking vacuum.

    摘要: Metal seed layers are deposited on a semiconductor substrate having recessed features by a method that involves at least three operations. In this method, a first layer of metal is deposited onto the substrate to cover at least the bottom portions of the recessed features. The first layer of metal is subsequently redistributed to improve sidewall coverage of the recessed features. Next, a second layer of metal is deposited on at least the field region of the substrate and on the bottom portions of the recessed features. The method can be implemented using a PVD apparatus that allows deposition and resputtering operations. This sequence of operations can afford seed layers with improved step coverage. It also leads to decreased formation of voids in interconnects, and to improved resistance characteristics of formed IC devices.
