Publication number: 20150050599Abstract: A method is disclosed to form a patterned epitaxy template, on a substrate, to direct self-assembly of block copolymer for device lithography. A resist layer on a substrate is selectively exposed with actinic (e.g. UV or DUV) radiation by photolithography to provide exposed portions in a regular lattice pattern of touching or overlapping shapes arranged to leave unexposed resist portions between the shapes. Exposed or unexposed resist is removed with remaining resist portions providing the basis for a patterned epitaxy template for the orientation of the self-assemblable block copolymer as a hexagonal or square array. The method allows for simple, direct UV lithography to form patterned epitaxy templates with sub-resolution features.Type: ApplicationFiled: March 19, 2013Publication date: February 19, 2015Applicant: ASML Netherlands B.V.Inventors: Sander Frederik Wuister, Vadim Yevgenyevich Banine, Jozef Maria Finders, Roelof Koole, Emiel Peeters, Harmeet Singh

Patent number: 8956789Abstract: Methods for fabricating integrated circuits are provided. In one example, a method for fabricating an integrated circuit includes patterning a first photoresist layer overlying a mask blank that is mounted on a first chuck to form a first patterned photoresist layer. The mask blank is selectively etched using the first patterned photoresist layer to form a first patterned mask. The first patterned mask is mounted on a second chuck and a non-flatness compensation is determined. The first patterned mask is mounted on the first chuck and a second photoresist layer is patterned overlying the first patterned mask to form a second patterned photoresist layer. The second patterned photoresist layer includes a device pattern that has been adjusted using the non-flatness compensation. The first patterned mask is selectively etched using the second patterned photoresist layer to form a second patterned mask.Type: GrantFiled: March 15, 2013Date of Patent: February 17, 2015Assignee: GLOBALFOUNDRIES, Inc.Inventor: Sudharshanan Raghunathan

Patent number: 8956804Abstract: A block copolymer, adapted to self-assemble to form an ordered pattern on a substrate, has first and second blocks with a terminal moiety covalently bonded to the end of the first block. The molecular weight of the terminal moiety is 20% or less than that of the block copolymer and the terminal moiety has a low chemical affinity for the first block. The terminal moiety can assist the accurate positional placement of the domains of the ordered array and lead to improved critical dimension uniformity and/or reduced line edge roughness. The polymer may be useful in combination with a graphoepitaxy template, where the terminal moiety is chosen to associate with a sidewall of the template. This may reduce undesired aggregation of polymer domains at a sidewall and/or assist in domain placement accuracy.Type: GrantFiled: June 7, 2012Date of Patent: February 17, 2015Assignee: ASML Netherlands B.V.Inventors: Aurelie Marie Andree Brizard, Sander Frederik Wuister, Roelof Koole, Emiel Peeters

Publication number: 20150044600Abstract: Double-exposure mask structure and photolithography. method for performing a photolithography process on a substrate are provided. The substrate has a central region and a margin region. A double-exposure mask structure includes a plurality of parallel and spaced first masks corresponding to the central region, a plurality of parallel and spaced second masks corresponding to the central region, and a plurality of auxiliary masks. The second masks intersect the first masks to form a plurality of overlapping regions. The auxiliary masks are not in contact with one another, and correspond to the Second masks to assist the overlapping regions neighboring to the auxiliary masks to have sufficient depth of focus for photolithography. With the auxiliary masks, the overlapping regions in the central region and neighboring to the margin region can have preferred photolithography and etching effect.Type: ApplicationFiled: August 12, 2013Publication date: February 12, 2015Applicant: Rexchip Electronics CorporationInventors: YUNG-WEN HUNG, CHENG-SHUAI LI, YUN-TING SHEN
