Publication number: 20110129781Abstract: In a photoresist composition, methods of forming a pattern using the same, and methods of manufacturing a semiconductor device using the same A photoresist film may be formed on a substrate by coating a photoresist composition including a polymer and a solvent. The polymer includes a first repeating unit and a second repeating unit. The first repeating unit has a diazoketo group and a second repeating unit has a group containing silicon. A photoresist pattern is formed by partially exposing the photoresist film and developing the photoresist film. A pattern having an improved etching resistance and uniformity of critical dimension is formed.Type: ApplicationFiled: November 23, 2010Publication date: June 2, 2011Inventors: Kyoung-Mi Kim, Young-Ho Kim

Patent number: 7947434Abstract: The process of forming a plated film according to the invention is designed such that the surface asperities of the inorganic film formed by the tracing of a standing wave occurring at the inner wall surface of the first opening in the resist at the resist pattern-formation step are reduced or eliminated. It is thus possible to form, efficiently yet in a short period of time, a high aspect-ratio plated film portion having an aspect ratio of greater than 1. In addition, the formed plated film quality is extremely improved for the absence of pores (cavities).Type: GrantFiled: February 6, 2007Date of Patent: May 24, 2011Assignee: TDK CorporationInventors: Akifumi Kamijima, Hitoshi Hatate, Hideyuki Yatsu

Patent number: 7943289Abstract: The invention provides systems and processes that form the inverse (photographic negative) of a patterned first coating. The patterned first coating is usually provided by a resist. After the first coating is patterned, a coating of a second material is provided thereover. The uppermost layer of the second coating is removed, where appropriate, to expose the patterned first coating. The patterned first coating is subsequently removed, leaving the second coating material in the form of a pattern that is the inverse pattern of the first coating pattern. The process may be repeated with a third coating material to reproduce the pattern of the first coating in a different material. Prior to applying the second coating, the patterned first coating may be trimmed by etching, thereby reducing the feature size and producing sublithographic features. In addition to providing sublithographic features, the invention gives a simple, efficient, and high fidelity method of obtaining inverse coating patterns.Type: GrantFiled: March 22, 2005Date of Patent: May 17, 2011Assignee: GLOBALFOUNDRIES Inc.Inventors: Bharath Rangarajan, Michael K.
