  • Patent number: 9385192
    Abstract: Aspects of the present invention generally relate to approaches for forming a semiconductor device such as a TSV device having a “buffer zone” or gap layer between the TSV and transistor(s). The gap layer is typically filled with a low stress thin film fill material that controls stresses and crack formation on the devices. Further, the gap layer ensures a certain spatial distance between TSVs and transistors to reduce the adverse effects of temperature excursion.

  • Publication number: 20150200111
    Abstract: Embodiments of the present invention provide improved methods for fabrication of finFETs. During finFET fabrication, a film, such as amorphous silicon, is deposited on a semiconductor substrate which has regions with fins and regions without fins. A fill layer is deposited on the film and planarized to form a flush surface. A recess or etch process is used to form a planar surface with all portions of the fill layer removed. A finishing process such as a gas cluster ion beam process may be used to further smooth the substrate surface. This results in a film having a very uniform thickness across the structure (e.g. a semiconductor wafer), resulting in improved within-wafer (WiW) uniformity and improved within-chip (WiC) uniformity.

  • Patent number: 6924234
    Abstract: In a method and apparatus for polishing a Cu metal layer and a method for forming Cu metal wiring, Cu oxide created by a surface oxidation of a Cu metal layer is removed from the wafer. The Cu metal layer, in which Cu oxide is removed, is polished. By polishing the Cu metal layer using the above method, process failures, such as scratches, caused by the presence of remnants of Cu oxide during subsequent polishing can be prevented.

  • Publication number: 20030017693
    Abstract: A method of manufacturing a semiconductor device for protecting a Cu layer from post chemical mechanical polishing (CMP) corrosion and CMP equipment therefore wherein, when wafers on which a Cu layer is formed wait to be transferred to a cleaning system after being polished in a CMP equipment, the wafers collected at a stand-by station are supplied with a solution containing a corrosion inhibitor, thus at least keeping the polished surface of Cu layer wet with the solution. Then, the wafers collected at the stand-by station are transferred to the cleaning system and cleaned. In the present invention, the solution uses a solution in which the corrosion inhibitor is added to de-ionized water. Furthermore, while transferring the wafers, the surfaces of the transferred wafers are kept wet with a solution containing a corrosion inhibitor.
