Publication number: 20140094031Abstract: According to one embodiment, a method for generating mask data is configured to form a circuit pattern on a substrate using a directed self-assembly material. The method includes extracting a first region, setting a second region and setting a third region. The first region does not existing in the circuit pattern and existing in an initial pattern. The initial pattern includes a plurality of interconnect patterns extending in a first direction. The second region is formed by elongating the first region in a second direction intersecting the first direction. The second region straddles the first region in the second direction. The third region includes at least one of the second regions. The directed self-assembly material is disposed in the third region.Type: ApplicationFiled: February 20, 2013Publication date: April 3, 2014Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Shimon MAEDA, Shinichi ITO

Publication number: 20140094033Abstract: A polishing composition of the present invention contains a water-soluble polymer having a hydrophilic group, and abrasive grains. A hydrophobic silicon-containing part after being polished with the polishing composition has a water contact angle lower than that of the hydrophobic silicon-containing part after being polished with another composition having the same makeup as the polishing composition except that the water-soluble polymer is not contained therein. Examples of the water-soluble polymer include polysaccharides and alcohol compounds. Another polishing composition of the present invention contains abrasive grains having a silanol group, and a water-soluble polymer. When this polishing composition is left to stand for one day in an environment at a temperature of 25° C., the water-soluble polymer is adsorbed on the abrasive grains at 5,000 or more molecules per 1 ?m2 of surface area of the abrasive grains.Type: ApplicationFiled: May 31, 2012Publication date: April 3, 2014Inventors: Yasuyuki Yamato, Youhei Takahashi, Tomohiko Akatsuka

Publication number: 20140094035Abstract: Techniques, systems, and apparatuses for performing carbon gap-fill in semiconductor wafers are provided. The techniques may include performing deposition-etching operations in a cyclic fashion to fill a gap feature with carbon. A plurality of such deposition-etching cycles may be performed, resulting in a localized build-up of carbon film on the top surface of the semiconductor wafer near the gap feature. An ashing operation may then be performed to preferentially remove the built-up material from the top surface of the semiconductor wafer. Further groups of deposition-etching cycles may then be performed, interspersed with further ashing cycles.Type: ApplicationFiled: May 17, 2013Publication date: April 3, 2014Applicant: Novellus Systems, Inc.Inventors: Chunhai Ji, Sirish Reddy, Tuo Wang, Mandyam Sriram

Publication number: 20140094037Abstract: A method for combinatorially processing a substrate is provided. The method includes introducing a first etchant into a reactor cell and introducing a fluid into the reactor cell while the first etchant remains in the reactor cell. After initiating the introducing the fluid, contents of the reactor cell are removed through a first removal line and a second removal line, wherein the first removal line extends farther into the reactor cell than the second removal line. A level of the fluid above an inlet to the first removal line is maintained while removing the contents. A second etchant is introduced into the reactor cell while removing the contents through the first removal line and the second removal line. The method includes continuing the introducing of the second etchant until a concentration of the second etchant is at a desired level, wherein the surface of the substrate remains submerged.Type: ApplicationFiled: December 4, 2013Publication date: April 3, 2014Applicant: Intermolecular, Inc.Inventors: Edwin Adhiprakasha, Shuogang Huang

Publication number: 20140094038Abstract: The present invention provides methods and apparatuses for improving adhesion of dielectric and conductive layers on a substrate to the underlying layer. The methods involve passing a process gas through a plasma generator downstream of the substrate to create reactive species. The underlying layer is then exposed to reactive species that interact with the film surface without undesirable sputtering. The gas is selected such that the interaction of the reactive species with the underlying layer modifies the surface of the layer in a manner that improves adhesion to the subsequently formed overlying layer. During exposure to the reactive species, the substrate and/or process gas may be exposed to ultraviolet radiation to enhance surface modification. In certain embodiments, a single UV cure tool is used to cure the underlying film and improve adhesion.Type: ApplicationFiled: September 13, 2013Publication date: April 3, 2014Applicant: Novellus Systems, Inc.Inventors: Jason Dirk Haverkamp, Dennis Hausmann, Roey Shaviv
