Patent number: 8524591Abstract: In semiconductor devices, integrity of a titanium nitride material may be increased by exposing the material to an oxygen plasma after forming a thin silicon nitride-based material. The oxygen plasma may result in an additional passivation of any minute surface portions which may not be appropriately covered by the silicon nitride-based material. Consequently, efficient cleaning recipes, such as cleaning processes based on SPM, may be performed after the additional passivation without undue material loss of the titanium nitride material. In this manner, sophisticated high-k metal gate stacks may be formed with a very thin protective liner material on the basis of efficient cleaning processes without unduly contributing to a pronounced yield loss in an early manufacturing stage.Type: GrantFiled: August 2, 2010Date of Patent: September 3, 2013Assignee: GLOBALFOUNDRIES Inc.Inventors: Sven Beyer, Rick Carter, Andreas Hellmich, Berthold Reimer

Patent number: 7442653Abstract: An exemplary manufacturing method of an inter-metal dielectric of a semiconductor device according to an embodiment of the present invention includes forming a first silicon-rich oxide (SRO) layer on a silicon substrate provided with or otherwise having a copper line layer therein, forming a plasma enhanced fluorosilicate glass (PEFSG) layer on the first SRO layer, plasma-treating the PEFSG layer, and forming a second SRO layer on the plasma-treated PEFSG layer. According to the present invention, the thickness of the second SRO layer of the inter-metal dielectric can be reduced. Consequently, process cost can be reduced, and the total thickness of the inter-metal dielectric can be reduced so as to lower the dielectric constant thereof, reduce the aspect ratio of any via holes that are subsequently formed in the inter-metal dielectric, and potentially increase the yield as a result of the reduced via hole aspect ratio.Type: GrantFiled: December 20, 2005Date of Patent: October 28, 2008Assignee: Dongbu Electronics Co., Ltd.Inventor: Tae-Young Lee

Patent number: 7381657Abstract: A biased pulse DC reactor for sputtering of oxide films is presented. The biased pulse DC reactor couples pulsed DC at a particular frequency to the target through a filter which filters out the effects of a bias power applied to the substrate, protecting the pulsed DC power supply. Films deposited utilizing the reactor have controllable material properties such as the index of refraction. Optical components such as waveguide amplifiers and multiplexers can be fabricated using processes performed on a reactor according to the present inention.Type: GrantFiled: October 1, 2004Date of Patent: June 3, 2008Assignee: SpringWorks, LLCInventors: Hongmei Zhang, Mukundan Narasimhan, Ravi B.

Patent number: 7341935Abstract: A semiconductor interconnect structure includes an organic and/or photosensitive etch buffer layer disposed over a contact surface. The structure further provides an interlevel dielectric formed over the etch buffer layer. A method for forming an interconnect structure includes etching to form an opening in the interlevel dielectric, the etching operation being terminated at or above the etch buffer layer. The etch buffer layer is removed to expose the contact surface using a removal process that may include wet etching, ashing or DUV exposure followed by developing or other techniques that do not result in damage to contact surface. The contact surface may be a conductive material such as silicide, salicide or a metal alloy.Type: GrantFiled: June 25, 2004Date of Patent: March 11, 2008Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Ju-Wang Hsu, Jyu-Horng Shieh, Yi-Chun Huang
