Patent number: 9018096Abstract: A method of manufacturing a structure comprising substantially planar electronic devices comprises providing an active material layer having a plurality of insulative features formed therein. The features at least partly inhibit electrical current flow and define at least a first substantially planar electronic device in the layer having at least first and second terminals comprising an area of the active material layer. A patterned dielectric layer having an exposed surface patterned with at least a first depression arranged over the first terminal is formed over the active material layer. Dielectric material is removed from at least a base of the first depression to expose a first terminal surface and form a hole through the dielectric material to the first terminal. The hole is at least partly filled with electrically conductive material to form an electrical connection to the first terminal. Corresponding structures and electrical circuits are also described and claimed.Type: GrantFiled: September 2, 2010Date of Patent: April 28, 2015Assignee: Pragmatic Printing Ltd.Inventors: Richard David Price, Ian Barton

Patent number: 8951900Abstract: The present disclosure is directed to, among other things, an illustrative method that includes forming an opening in a dielectric material of a contact level of a semiconductor device, and selectively depositing a conductive material in the opening to form a contact element therein, the contact element extending to a contact area of a circuit element and having a laterally restricted excess portion formed outside of the opening and above the dielectric material. The disclosed method further includes forming a sacrificial material layer above the dielectric material and the contact element, the sacrificial material layer surrounding the laterally restricted excess portion. Additionally, the method includes planarizing a surface topography of the contact level in the presence of the sacrificial material so as to remove the laterally restricted excess portion from above the dielectric material.Type: GrantFiled: April 25, 2013Date of Patent: February 10, 2015Assignee: GLOBALFOUNDRIES Inc.Inventors: Axel Preusse, Norbert Schroeder, Uwe Stoeckgen

Patent number: 8906805Abstract: A method of fabricating a semiconductor device includes forming a stacked structure in which 2n (here, n is an integer which is 2 or more) deposited sacrificial layers and 2n deposited insulating layers disposed on the 2n deposited sacrificial layers respectively are alternately deposited in a third direction perpendicular to a first direction and a second direction on a substrate having an upper surface extending in the first and second directions which are perpendicular to each other. Methods include forming a recess group including 2n?1 first recesses penetrating 20 through 2n?1 deposited sacrificial layers and forming a buried insulating layer group including 2n?1 buried insulating layers filling the 2n?1 first recesses respectively. A contact plug group including 2n contact plugs penetrating an uppermost deposited insulating layer of the 2n deposited insulating layers and the 2n?1 buried insulating layers may be formed.Type: GrantFiled: March 13, 2012Date of Patent: December 9, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Sang-yong Park, Woon-kyung Lee, Jin-taek Park

Patent number: 8890262Abstract: Provided is a semiconductor device (e.g., transistor such as a FinFET or planar device) having a a liner layer and a metal layer (e.g., Tungsten (W)) in a trench (e.g., via CVD and/or ALD). A single chamber (e.g., an extreme fill chamber) will be utilized to separately etch back the liner layer and the metal layer. In general, the liner layer may be etched back further than the metal layer to provide for larger contact and lower resistance. After etching is complete, a bottom-up fill/growth of metal (e.g., W) will be performed (e.g., via CVD in a W chamber or the like) to increase the presence of gate metal in the trench.Type: GrantFiled: November 29, 2012Date of Patent: November 18, 2014Assignee: GLOBALFOUNDRIES Inc.Inventors: Vimal Kamineni, Ruilong Xie
