The conductive via material within corresponding via openings of adjacent insulator layers are electrically connected to form continuous electrical via paths through the insulator layers between the top surface and the bottom surface of the laminated structure. Within each of the continuous electrical via paths, the via openings are positioned relative to each other to form a diagonal structural path of the conductive via material through the laminated structure. The corresponding via openings of the adjacent insulator layers partially overlap each other. The diagonal structural paths are non-perpendicular to the top surface and the bottom surface.Type: GrantFiled: April 30, 2012Date of Patent: June 24, 2014Assignee: International Business Machines CorporationInventors: Luke D. LaCroix, Mark C. H. Lamorey, Janak G. Patel, Peter Slota, Jr., David B. Stone

Patent number: 8735302Abstract: Metal gate high-k capacitor structures with lithography patterning are used to extract gate work function using a combinatorial workflow. Oxide terracing, together with high productivity combinatorial process flow for metal deposition can provide optimum high-k gate dielectric and metal gate solutions for high performance logic transistors. The high productivity combinatorial technique can provide an evaluation of effective work function for given high-k dielectric metal gate stacks for PMOS and NMOS transistors, which is critical in identifying and selecting the right materials.Type: GrantFiled: May 24, 2012Date of Patent: May 27, 2014Assignee: Intermolecular, Inc.Inventors: Amol Joshi, John Foster, Zhendong Hong, Olov Karlsson, Bei Li, Usha Raghuram

Patent number: 8629031Abstract: It is an object of the present invention to provide a method for manufacturing an SOI substrate having an SOI layer that can be used in practical applications with high yield even when a flexible substrate such as a glass substrate or a plastic substrate is used. Further, it is another object of the present invention to provide a method for manufacturing a thin semiconductor device using such an SOI substrate with high yield. When a single-crystal semiconductor substrate is bonded to a flexible substrate having an insulating surface and the single-crystal semiconductor substrate is separated to manufacture an SOI substrate, one or both of bonding surfaces are activated, and then the flexible substrate having an insulating surface and the single-crystal semiconductor substrate are attached to each other.Type: GrantFiled: February 5, 2013Date of Patent: January 14, 2014Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Yasuhiro Jinbo, Hironobu Shoji, Hideto Ohnuma, Shunpei Yamazaki

Patent number: 8603899Abstract: At present, a forming process of a base film through an amorphous silicon film is conducted in respective film forming chambers in order to obtain satisfactory films. When continuous formation of the base film through the amorphous silicon film is performed in a single film forming chamber with the above film formation condition, crystallization is not sufficiently attained in a crystallization process. By forming the amorphous silicon film using silane gas diluted with hydrogen, crystallization is sufficiently attained in the crystallization process even with the continuous formation of the base film through the amorphous silicon film in the single film forming chamber.Type: GrantFiled: October 25, 2012Date of Patent: December 10, 2013Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Taketomi Asami, Mitsuhiro Ichijo, Satoshi Toriumi

Patent number: 8586475Abstract: A gate insulating film and a gate electrode of non-single crystalline silicon for forming an nMOS transistor are provided on a silicon substrate. Using the gate electrode as a mask, n-type dopants having a relatively large mass number (70 or more) such as As ions or Sb ions are implanted, to form a source/drain region of the nMOS transistor, whereby the gate electrode is amorphized. Subsequently, a silicon oxide film is provided to cover the gate electrode, at a temperature which is less than the one at which recrystallization of the gate electrode occurs. Thereafter, thermal processing is performed at a temperature of about 1000° C., whereby high compressive residual stress is exerted on the gate electrode, and high tensile stress is applied to a channel region under the gate electrode. As a result, carrier mobility of the nMOS transistor is enhanced.Type: GrantFiled: January 16, 2013Date of Patent: November 19, 2013Assignee: Renesas Electronics CorporationInventors: Hirokazu Sayama, Kazunobu Ohta, Hidekazu Oda, Kouhei Sugihara
