Patent number: 11004612Abstract: MIM capacitors using low temperature sub-nanometer periodic stack dielectrics (SN-PSD) containing repeating units of alternating high dielectric constant materials sublayer and low leakage dielectric sublayer are provided. Every sublayer has thickness less than 1 nm (sub nanometer). The high dielectric constant materials could be one or more different materials. The low leakage dielectric materials could be one or more different materials. For the SN-PSD containing more than two different materials, those materials are deposited in sequence with the leakage current of the materials from the lowest to the highest and then back to the second-lowest, or with the energy band gap of the materials from the widest to the narrowest and then back to the second widest in each periodic cell. A layer of low leakage current dielectric materials is deposited on and/or under SN-PSD. The dielectric constant of SN-PSD is much larger than that of the component oxides and can be readily deposited at 250° C.Type: GrantFiled: March 14, 2019Date of Patent: May 11, 2021Assignee: MicroSol Technologies Inc.Inventors: Yuanning Chen, Jesus Israel Mejia Silva, Chunya Wu, Deborah Jean Riley, Yun-Ju Lee

Patent number: 7800226Abstract: A method for forming a metal silicide region in a silicon region of a semiconductor substrate. The method comprises forming a metal layer over the silicon region, then in succession forming a titanium and a titanium nitride layer thereover. As the substrate is heated to form the silicide, the titanium getters silicon dioxide on the surface of the silicon region and the titanium nitride promotes the formation of a smooth surface at the interface between the silicide layer and the underlying silicon region.Type: GrantFiled: June 22, 2007Date of Patent: September 21, 2010Assignee: Agere Systems Inc.Inventors: Yuanning Chen, Maxwell Walthour Lippitt, III, William M.

Patent number: 7704883Abstract: A method for manufacturing a semiconductor device. The method comprises depositing a material layer on a semiconductor substrate and patterning the material layer with a patterning material. Patterning forms a patterned structure of a semiconductor device, wherein the patterned structure has a sidewall with a roughness associated therewith. The method also comprises removing the patterning material from the patterned structure and annealing an outer surface of the patterned structure such that the roughness is reduced.Type: GrantFiled: December 22, 2006Date of Patent: April 27, 2010Assignee: Texas Instruments IncorporatedInventors: Stephanie W.

Patent number: 7569464Abstract: The present invention provides a method for manufacturing a semiconductor device, which includes forming a gate structure over a substrate, and forming a stack of layers on the substrate and at least partially along a sidewall of the gate structure. In this embodiment, the stack of layers includes an initial layer located over the substrate, a buffer layer located over the initial layer and an offset layer located over the buffer layer. This embodiment of the method further includes removing horizontal segments of the offset layer and the buffer layer using a dry etch and a wet clean, wherein removing includes choosing at least one of an initial thickness of the buffer layer, a period of time for the dry etch or a period of time for the wet clean such that horizontal segments of the initial layer are exposed and substantially unaffected after the dry etch and wet clean.Type: GrantFiled: December 22, 2006Date of Patent: August 4, 2009Assignee: Texas Instruments IncorporatedInventors: Karen H.
