Patent number: 8298936Abstract: Metal seed layers are deposited on a semiconductor substrate having recessed features by a method that involves at least three operations. In this method, a first layer of metal is deposited onto the substrate to cover at least the bottom portions of the recessed features. The first layer of metal is subsequently redistributed to improve sidewall coverage of the recessed features. Next, a second layer of metal is deposited on at least the field region of the substrate and on the bottom portions of the recessed features. The method can be implemented using a PVD apparatus that allows deposition and resputtering operations. This sequence of operations can afford seed layers with improved step coverage. It also leads to decreased formation of voids in interconnects, and to improved resistance characteristics of formed IC devices.Type: GrantFiled: February 3, 2010Date of Patent: October 30, 2012Assignee: Novellus Systems, Inc.Inventors: Robert Rozbicki, Bart van Schravendijk, Thomas Mountsier, Wen Wu

Patent number: 8288297Abstract: Embodiments of the invention generally relate to nonvolatile memory devices, such as a ReRAM cells, and methods for manufacturing such memory devices, which includes optimized, atomic layer deposition (ALD) processes for forming metal oxide film stacks. The metal oxide film stacks contain a metal oxide coupling layer disposed on a metal oxide host layer, each layer having different grain structures/sizes. The interface disposed between the metal oxide layers facilitates oxygen vacancy movement. In many examples, the interface is a misaligned grain interface containing numerous grain boundaries extending parallel to the electrode interfaces, in contrast to the grains in the bulk film extending perpendicular to the electrode interfaces. As a result, oxygen vacancies are trapped and released during switching without significant loss of vacancies.Type: GrantFiled: September 1, 2011Date of Patent: October 16, 2012Assignee: Intermolecular, Inc.Inventors: Yun Wang, Vidyut Gopal, Imran Hashim, Dipankar Pramanik, Tony Chiag

Patent number: 8247905Abstract: The present invention is related to a method for forming vertical conductive structures by electroplating. Specifically, a template structure is first formed, which includes a substrate, a discrete metal contact pad located on the substrate surface, an inter-level dielectric (ILD) layer over both the discrete metal contact pad and the substrate, and a metal via structure extending through the ILD layer onto the discrete metal contact pad. Next, a vertical via is formed in the template structure, which extends through the ILD layer onto the discrete metal contact pad. A vertical conductive structure is then formed in the vertical via by electroplating, which is conducted by applying an electroplating current to the discrete metal contact pad through the metal via structure. Preferably, the template structure comprises multiple discrete metal contact pads, multiple metal via structures, and multiple vertical vias for formation of multiple vertical conductive structures.Type: GrantFiled: August 10, 2009Date of Patent: August 21, 2012Assignee: International Business Machines CorporationInventors: Hariklia Deligianni, Qiang Huang, John P.
