Patent number: 8273668Abstract: Methods of forming a pattern and methods of fabricating a semiconductor device having a pattern are provided, the methods include forming a self-assembly induction layer including a first region and a second region on a semiconductor substrate. A block copolymer layer is coated on the self-assembly induction layer. A first pattern, a second pattern and a third pattern are formed by phase separating the block copolymer. At least one of the first, second and third patterns may be removed to form a preliminary pattern. An etching process may be performed using the preliminary pattern as an etching mask. The first pattern contains the same material as that of the second pattern, and the third pattern contains a material different from that of the first pattern.Type: GrantFiled: July 30, 2010Date of Patent: September 25, 2012Assignees: Samsung Electronics Co., Ltd., Korea Advanced Institute of Science and TechnologyInventors: Dong Ki Yoon, Shiyong Yi, Kyoungseon Kim, Seongwoon Choi, Seokhwan Oh, Sang Ouk Kim, Seung Hak Park

Patent number: 8274146Abstract: An integrated circuit includes a high speed circuit, an interconnect pad, a passivation layer under the interconnect pad, a first patterned metal layer, and a first via. The high speed circuit is for a high speed signal at a terminal of the high speed circuit. The interconnect pad is on a top surface of the integrated circuit structure. The first patterned metal layer is under the passivation layer having a first portion and a second portion. The first portion of the first patterned metal layer is connected to the terminal of the high speed circuit. The second portion of the first patterned metal layer is under the interconnect pad and is electrically floating when the high frequency signal is present on the interconnect pad portion. The result is reduced capacitive loading on the high speed signal which improves performance.Type: GrantFiled: May 30, 2008Date of Patent: September 25, 2012Assignee: Freescale Semiconductor, Inc.Inventors: Michael A. Stockinger, Kevin J. Hess, James W. Miller

Patent number: 8268730Abstract: A method for fabricating semiconductor device structures includes forming a non-conformal mask over a surface of a substrate. Non-conformal mask material with a planar or substantially planar upper surface is formed on the surface of the substrate. The planarity or substantial planarity of the non-conformal material eliminates or substantially eliminates distortion in a “mask” formed thereover and, thus, eliminates or substantially eliminates distortion in any mask that is subsequently formed using the pattern of the mask. In some embodiments, mask material of the non-conformal mask does not extend into recesses in the upper surface of the substrate; instead it “bridges” the recesses. Semiconductor device structures that include non-conformal masks and semiconductor device structures that have been fabricated with non-conformal masks are also disclosed.Type: GrantFiled: June 3, 2009Date of Patent: September 18, 2012Assignee: Micron Technology, Inc.Inventor: David H. Wells
