  • Patent number: 9040121
    Abstract: Vacuum deposited thin films of material are described to create an interface that non-preferentially interacts with different domains of an underlying block copolymer film. The non-preferential interface prevents formation of a wetting layer and influences the orientation of domains in the block copolymer. The purpose of the deposited polymer is to produce nanostructured features in a block copolymer film that can serve as lithographic patterns.

  • Publication number: 20130323777
    Abstract: A ligand design allows compact nanoparticle materials, such as quantum dots (QDs), with excellent colloidal stability over a wide range of pH and under high salt concentrations. Self-assembled biomolecular conjugates with QDs can be obtained which are stable in biological environments. Energy transfer with these ligands is maximized by minimizing distances between QDs/nanoparticles and donors/acceptors directly attached to the ligands or assembled on their surfaces.

  • Patent number: 8592980
    Abstract: An interconnect structure for use in an integrated circuit is provided. The interconnect structure includes a first low-K dielectric material. The first low-K material may be modified with a first group of carbon nanotubes (CNTs) and disposed on a metal line. The first low-K material is modified by dispersing the first group of CNTs in a solution, spinning the solution onto a silicon wafer and curing the solution to form the first low-K material modified with the first CNTs. The metal line includes a top layer and a bottom layer connected by a metal via. The interconnect structure also includes a second low-K dielectric material modified with a second group of CNTs and disposed on the bottom layer. Accordingly, embodiments the present disclosure could help to increase the mechanical strength of the low-K material or the entire interconnect structure.
