摘要: The disclosure provides mechanisms of performing metal chemical-mechanical polishing (CMP) without significant loss of copper and a dielectric film of damascene structures. The mechanisms use a metal CMP stop layer made of a low-k dielectric film with a porogen, which significantly reduces the removal rate of the metal CMP stop layer by metal CMP. The metal CMP stop layer is converted into a porous low-k dielectric film after a cure (or curing) to remove or convert the porogen. The low-k value, such as equal to or less than about 2.6, of the metal CMP stop layer makes the impact of using of the metal CMP stop layer on RC delay from minimum to none. Further the CMP stop layer protects the porous low-k dielectric film underneath from exposure to water, organic compounds, and mobile ions in the CMP slurry.

摘要: A method for thinning a wafer is provided. In one embodiment, a wafer is provided having a plurality of semiconductor chips, the wafer having a first side and a second side opposite the first side, wherein each of the chips includes a set of through silicon vias (TSVs), each of the TSVs substantially sealed by a liner layer and a barrier layer. A wafer carrier is provided for attaching to the second side of the wafer. The first side of the wafer is thinned and thereafer recessed to partially expose portions of the liner layers, barrier layers and the TSVs protruding from the wafer. An isolation layer is deposited over the first side of the wafer and the top portions of the liner layers, barrier layers and the TSVs. Thereafter, an insulation layer is deposited over the isolation layer. The insulation layer is then planarized to expose top portions of the TSVs. A dielectric layer is deposited over the planarized first side of the wafer. One or more electrical contacts are formed in the dielectric layer for electrical connection to the exposed one or more TSVs.
