  • Patent number: 10937940
    Abstract: There are two parts to build fusion carbon metal interconnects. First are the fusing metals/alloys, typically in the Martensite phase and lacking carbon. Second are carbonized materials that have carbon infused. These carbonized materials may be referred to as carbon donating materials. Both parts can be interchanged as the substrate or mounted component, or the parts can form linear interface connections. The finished interfaces have very low electrical resistance and/or zero interface electrical resistance. The interconnect circuit topography materials and connections are endless and is dependent on circuit design. One example of such interface is a solderless thermoelectric device capable of use at higher operating temperatures as compared to conventional low temperature solders thus allowing the thermoelectric device to be used in a Seebeck device, for example. The thermoelectric device forms a fusion layer between a copper metal layer and a semiconductor wafer layer to create a true metallurgical bond.

  • Patent number: 10493527
    Abstract: An additive manufacturing system for printing an article including a build plate having a build surface between an inner radius and an outer radius that may receive powder particles and a recoating assembly that may distribute the powder particles onto the build surface to form a build layer of the article. The recoating assembly includes a support jig having a first end, a second end, and a support wall extending between the first and second ends and a recoater blade coupled to the second end and extending along at least a portion of a length of the support wall. A shape of the recoater blade is such that, when the recoater blade is positioned against the build surface, an angle between the recoater blade and a tangent at each radii of the build plate is substantially constant.

  • Patent number: 9698708
    Abstract: Techniques and systems are disclosed for locomoting fuel-free nanomotors in a fluid. In one aspect of the disclosed technology, a system for locomoting fuel-free nanomotors can include an electrically-driven nanowire diode formed of two or more segments of different electrically conducting materials, a fluid container, and a mechanism that produces an electric field to drive the nanowire diode to locomote in the fluid. In another aspect, a system for locomoting fuel-free nanomotors can include a magnetically-propelled multi-segment nanowire motor formed of a magnetic segment and a flexible joint segment, a fluid container, and a mechanism that generates and controls a magnetic field to drive the multi-segment nanowire motor to locomote in the fluid. The disclosed fuel-free nanomotors can obviate fuel requirements and can be implemented for practical in vitro and in vivo biomedical applications.

  • Patent number: 9349604
    Abstract: A method is provided for forming a patterned topography on a substrate. The substrate is provided with features formed atop that constitute an existing topography, and a template for directed self-assembly (DSA) surrounds the exposed topography. Further to the method, the template is filled with a block copolymer (BCP) to cover the exposed topography, and then the BCP is annealed within the template to drive self-assembly in alignment with the topography. Developing the annealed BCP exposes a DSA pattern immediately overlying the topography.

  • Patent number: 9229324
    Abstract: A method is disclosed to form a patterned template on a substrate, to direct orientation of a self-assemblable block copolymer. The method involves providing a resist layer of a positive tone resist on the substrate and overexposing the resist with actinic (e.g. UV) radiation by photolithography to expose a continuous region of the resist layer with a sub-resolution unexposed resist portion at the interface between the resist and the substrate. The resist portion remaining at the interface, after removal of the exposed region, provides a basis for a chemical epitaxy template. The method may allow for simple, direct photolithography to form a patterned chemical epitaxy template and optionally include an accurately co-aligned graphoepitaxy feature and/or a substrate alignment feature.
