    摘要: Embodiments of a polisher for chemical mechanical planarization. The polisher includes a polishing pad structure containing a first reactant therein, and a second reactant in a polishing environment over the polishing pad structure. The first reactant and the second reactant react endothermically upon contact when polishing a wafer surface between the polishing pad structure and the polishing environment.

    摘要: The present disclosure provides a method for fabricating an integrated circuit. The method includes forming an energy removable film (ERF) on a substrate; forming a first dielectric layer on the ERF; patterning the ERF and first dielectric layer to form a trench in the ERF and the first dielectric layer; filling a conductive material in the trench; forming a ceiling layer on the first dielectric layer and conductive material filled in the trench; and applying energy to the ERF to form air gaps in the ERF after the forming of the ceiling layer.

    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.
