  • Patent number: 10814457
    Abstract: A gimbal for a conditioning system for a CMP tool is configured to maintain a conditioning disk in contact with a polishing pad of the CMP tool. The gimbal includes an arm coupling for coupling to a conditioning swing arm of the CMP tool; and a disk holder for holding the conditioning disk. A flexible diaphragm extends between the arm coupling and the disk holder. The flexible diaphragm allows the disk holder to flex relative to the arm coupling. The flexible diaphragm is made of a metal or metal alloy.
    Type: Grant

  • Patent number: 8889537
    Abstract: A method for formation of a segregated interfacial dopant layer at a junction between a semiconductor material and a silicide layer includes depositing a doped metal layer over the semiconductor material; annealing the doped metal layer and the semiconductor material, wherein the anneal causes a portion of the doped metal layer and a portion of the semiconductor material to react to form the silicide layer on the semiconductor material, and wherein the anneal further causes the segregated interfacial dopant layer to form between the semiconductor material and the silicide layer, the segregated interfacial dopant layer comprising dopants from the doped metal layer; and removing an unreacted portion of the doped metal layer from the silicide layer.

  • Patent number: 8524606
    Abstract: Planarization methods include depositing a mask material on top of an overburden layer on a semiconductor wafer. The mask material is planarized to remove the mask material from up areas of the overburden layer to expose the overburden layer without removing the mask material from down areas. The exposed overburden layer is wet etched and leaves a thickness remaining over an underlying layer. Remaining portions of the mask layer and the exposed portions of the overburden layer are planarized to expose the underlying layer.

  • Patent number: 8513127
    Abstract: A planarization method includes planarizing a semiconductor wafer in a first chemical mechanical polish step to remove overburden and planarize a top layer leaving a thickness of top layer material over underlying layers. The top layer material is planarized in a second chemical mechanical polish step to further remove the top layer and expose underlying layers of a second material and a third material such that a selectivity of the top layer material to the second material to the third material is between about 1:1:1 to about 2:1:1 to provide a planar topography.

  • Patent number: 8507383
    Abstract: Methods for polishing multiple dielectric layers to form replacement metal gate structures include a first chemical mechanical polish step to remove overburden and planarize a top layer to leave a planarized thickness over a gate structure. A second chemical mechanical polish step includes removal of the thickness to expose an underlying covered surface of a dielectric of the gate structure with a slurry configured to polish the top layer and the underlying covered surface substantially equally to accomplish a planar topography. A third chemical mechanical polish step is employed to remove the dielectric of the gate structure and expose a gate conductor.

  • Patent number: 8497210
    Abstract: A polishing method includes polishing, in a first polish, a wafer to remove overburden and planarize a top layer leaving a portion remaining on an underlying layer. A second polishing step includes two phases. In a first phase, the top layer is removed and the underlying layer is exposed, with a top layer to underlying layer selectivity of between about 1:1 to about 2:1 to provide a planar topography. In a second phase, residual portions of the top layer are removed from a top of the underlying layer to ensure complete exposure of an underlying layer surface.
