A remaining portion of the gate conductor layer includes an integral conductor structure, which includes a first portion overlying a gate dielectric over an active region and a second portion contacting the semiconductor material of the same active region or a different active region. The gate dielectric layer can be deposited within gate cavities in planarization dielectric material layer in a replacement gate scheme, or can be deposited on planar surfaces of active regions and/or shallow trench isolation structures in a gate first processing scheme.Type: GrantFiled: January 2, 2014Date of Patent: February 16, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Viraj Y.

Patent number: 9263459Abstract: A three dimensional or stacked circuit device includes a conductive channel cap on a conductor channel. The channel cap can be created via selective deposition or other process to prevent polishing down the conductive material to isolate the contacts. The conductor channel extends through a deck of multiple tiers of circuit elements that are activated via a gate. The gate is activated by electrical potential in the conductor channel. The conductive cap on the conductor channel can electrically connect the conductor channel to a bitline or other signal line, and/or to another deck of multiple circuit elements.Type: GrantFiled: September 26, 2014Date of Patent: February 16, 2016Assignee: Intel CorporationInventors: Hongqi Li, Gowrisankar Damarla, Roger Lindsay, Zailong Bian, Jin Lu, Shyam Ramalingam, Prasanna Srinivasan

Patent number: 9263464Abstract: Disposable gate structures and a planarization dielectric layer are formed over doped semiconductor material portions on a crystalline insulator layer. Gate cavities are formed by removing the disposable gate structures selective to the planarization dielectric layer. Doped semiconductor material portions are removed from underneath the gate cavities to provide pairs of source and drain regions separated by a gate cavity. Within a first gate cavity, a faceted crystalline dielectric material portion is grown from a physically exposed surface of the crystalline insulator layer, while a second gate is temporarily coated with an amorphous material layer. A contoured semiconductor region is epitaxially grown on the faceted crystalline dielectric material portion in the first gate cavity, while a planar semiconductor region is epitaxially grown in the second gate cavity. The semiconductor regions can provide at least one contoured channel region and at least one planar channel region.Type: GrantFiled: May 5, 2014Date of Patent: February 16, 2016Assignee: International Business Machines CorporationInventors: Anirban Basu, Pouya Hashemi

Patent number: 9263465Abstract: An apparatus and a method for creating a CMOS with a dual raised source and drain for NMOS and PMOS. The spacers on both stack gates are of equal thickness. In this method, a first insulating layer is formed on the surface. The first region is then masked while the other region has the first layer etched away and has an epitaxial source and drain grown on the region. A second layer is formed to all exposed surfaces. The second region is then masked while the first region is etched away. The epitaxial source and drain is formed on the first region. The second region can also be masked by adding a thin layer of undoped silicon and then oxidize it. Another way to mask the second region is to use a hard mask. Another way to form the second source and drain is to use amorphous material.Type: GrantFiled: January 29, 2015Date of Patent: February 16, 2016Assignee: GLOBALFOUNDRIES INC.Inventors: Kangguo Cheng, Bruce B.
