  • Publication number: 20160342089
    Abstract: A method uses a topographic pattern for directed self-assembly (DSA) of block copolymers (BCPs). Conventional lithography generates a topographic pattern of guiding stripes that have sidewalls that preferentially wet one of the blocks. A BCP blend with functional homopolymers, called “inks”, is deposited and annealed on the topographic pattern. After annealing, the BCP blend is guided to self-assemble by the topographic pattern. The inks selectively distribute into blocks, and part of the inks graft in the trenches between the topographic features. The BCP blend layer is rinsed away, leaving the grafted inks that form a chemical pattern. A second layer of BCP is deposited on this chemical pattern and annealed, resulting in DSA of the second BCP. After removal of one of the BCP blocks of the second BCP, the remaining blocks can serve as an etch mask.

  • Publication number: 20160319427
    Abstract: Block copolymers (BCPs) and synthetic infiltration synthesis (SIS) are used to double the line density on a substrate. The BCP comprises first and second interconnected BCP components with a functional group at the junction or interface of the components. After deposition of the BCP on the substrate and annealing, a pattern of parallel stripes of first and second BCP components is formed with a pattern of functional group interfaces between the components. Each of the BCP components is non-reactive with atomic layer deposition (ALD) precursors, while the functional group is reactive with the ALD precursors. The ALD results in the infiltration of inorganic material into the interfaces where the reactive functional groups are located but without affecting the BCP components. After removal of the organic material, a pattern of parallel lines of inorganic material remains with a pitch half that of the stripes of BCP components.

  • Patent number: 9458531
    Abstract: A guiding pattern for directed self-assembly (DSA) of a block copolymer (BCP) is an array of spaced guiding stripes on a substrate that have a width equal to nL0 and a pitch equal to (n+k)L0, where n and k are integers equal to or greater than 1 and L0 is the natural pitch of the BCP. The guiding stripes have oxidized sidewalls. A silicon-containing BCP self-assembles with the BCP component without silicon wetting the oxidized sidewalls. Then oxygen reactive ion etching (RIE) removes the BCP component without silicon and oxidizes the silicon-containing BCP component. The remaining pattern of silicon oxide containing BCP component can then be used as an etch mask to etch the underlying substrate.

  • Patent number: 9431219
    Abstract: A method that uses both electron beam (e-beam) lithography and directed self-assembly (DSA) of block copolymers (BCPs) makes guiding lines with oxidized sidewalls for use in subsequent DSA of BCPs. A series of films is deposited on a substrate including a first cross-linked polymer mat layer, a layer of resist, an etch stop layer resistant to oxygen reactive-ion-etching, a second cross-linked polymer mat layer, and an e-beam resist. After patterning and etching the second mat layer, a BCP self-assembles onto the patterned second mat layer and one of the BCP components is removed. Then the second mat layer is etched, using the remaining BCP component as an etch mask. Additional etching steps then create guiding lines of the first mat layer with oxidized sidewalls. The resulting guiding lines have better quality and lower roughness than guiding lines made with just e-beam lithography.

  • Publication number: 20160133292
    Abstract: Methods to pattern substrates with dense periodic nanostructures that combine top-down lithographic tools and self-assembling block copolymer materials are provided. According to various embodiments, the methods involve chemically patterning a substrate, depositing a block copolymer film on the chemically patterned imaging layer, and allowing the block copolymer to self-assemble in the presence of the chemically patterned substrate, thereby producing a pattern in the block copolymer film that is improved over the substrate pattern in terms feature size, shape, and uniformity, as well as regular spacing between arrays of features and between the features within each array compared to the substrate pattern. In certain embodiments, the density and total number of pattern features in the block copolymer film is also increased. High density and quality nanoimprint templates and other nanopatterned structures are also provided.

  • Patent number: 9336809
    Abstract: A method to fabricate an imprint template for bit-patterned magnetic recording media using block copolymers (BCPs) integrates data region patterning and servo region patterning. A heat sink layer is formed on the imprint substrate only in the data regions. A sublayer for the BCP is deposited over both the data regions and the servo regions and patterned to form stripes in the data regions and servo features in the servo regions. A BCP is then deposited in both the data and servo regions. Only the BCP in the data regions is heated, which causes phase separation of the BCP in the data regions into the two BCP components. The selective heating may be accomplished by directed controlled laser radiation to only the data regions. The heat sink layer below the data regions absorbs the heat from the laser radiation, confining it to the data regions.

  • Patent number: 9251835
    Abstract: A patterned magnetic media having offset servo and data regions. The media can be constructed by a method that allows both a data region and a servo region to be patterned without the patterning of one region adversely affecting the patterning of the other region. The method results in a patterned data region a patterned servo region and intermediate regions between the servo and data regions. The intermediate regions, which are most likely, but not necessarily, asymmetrical with one another indicate that the method has been used to pattern the media.
