Abstract:
Prefabricated exterior panels and slab foundation systems are disclosed for use in an integrated simple design procedure for use in low-energy use buildings. The panels include a frame formed from conventional framing methods, an inner layer of sheathing fastened to an outer side of the frame, a layer of insulation adhered to an outer surface of the inner layer of sheathing without using fasteners, and an outer layer of sheathing adhered to an outer surface said layer of insulation without using fasteners. Sets of panels are formed with openings for windows or doors. Jigs are used for constructing the panels including corner panels.
Abstract:
Embodiments of the present invention are directed to the formation of microprobe tips elements having a variety of configurations. In some embodiments tips are formed from the same building material as the probes themselves, while in other embodiments the tips may be formed from a different material and/or may include a coating material. In some embodiments, the tips are formed before the main portions of the probes and the tips are formed in proximity to or in contact with a temporary substrate. Probe tip patterning may occur in a variety of different ways, including, for example, via molding in patterned holes that have been isotropically or anisotropically etched silicon, via molding in voids formed in exposed photoresist, via molding in voids in a sacrificial material that have formed as a result of the sacrificial material mushrooming over carefully sized and located regions of dielectric material, via isotropic etching of the tip material around carefully sized and placed etching shields, via hot pressing, and the like.
Abstract:
A structure and method for improving the spatial resolution of a scanning probe microscope (SPM) tip, which has been coated with a layer of chemically-synthesized nanoparticles. The nanoparticles are either single-species or heterogeneous, such that the single-species nanoparticles can be either ferromagnetic, paramagnetic, superparamagnetic, antiferromagnetic, ferrimagnetic, magneto-optic, ferroelectric, piezoelectric, superconducting, semiconducting, magnetically-doped semiconducting, insulating, fluorescent, or chemically catalytic. The layer of nanoparticles is at least two nanoparticles thick, or alternatively, is a single layer of nanoparticles thick, or alternatively, is a single layer of nanoparticles thick and covers only the tip apex portion of the tip, or alternatively, only a single nanoparticle is affixed to the tip apex. Alternatively, the layer of nanoparticles is transformed into an electrically-continuous magnetic film by annealing at a high temperature.
Abstract:
Enhanced Electrochemical fabrication processes are provided that can form three-dimensional multi-layer structures using semiconductor based circuitry as a substrate. Electrically functional portions of the structure are formed from structural material (e.g. nickel) that adheres to contact pads of the circuit. Aluminum contact pads and silicon structures are protected from copper diffusion damage by application of appropriate barrier layers.
Abstract:
Embodiments disclosed herein are directed to compliant probe structures for making temporary or permanent contact with electronic circuits and the like. In particular, embodiments are directed to various designs of two-part probe elements, socket-able probes and their mounts. Some embodiments are directed to methods for fabricating such probes and mounts. In some embodiments, for example, probes have slide in mounting structures, twist in mounting structures, mounting structures that include compliant elements, and the like.
Abstract:
An electroplating method that includes: a) contacting a first substrate with a first article, which includes a substrate and a conformable mask disposed in a pattern on the substrate; b) electroplating a first metal from a source of metal ions onto the first substrate in a first pattern, the first pattern corresponding to the complement of the conformable mask pattern; and c) removing the first article from the first substrate, is disclosed. Electroplating articles and electroplating apparatus are also disclosed.

Abstract:
Multi-layer fabrication methods (e.g. electrochemical fabrication methods) for forming microscale and mesoscale devices or structures (e.g. turbines) provide bushings or roller bearing that allow rotational or linear motion which is constrained by multiple structural elements spaced from one another by gaps that are effectively less than minimum features sizes associated with the individual layers used to form the structures. In some embodiments, features or protrusions formed on different layers on opposing surfaces are offset along the axis of layer stacking so as to bring the features into positions that are closer than allowed by the minimum features sizes associated with individual layers. In other embodiments, interference is used to create effective spacings that are less than the minimum features sizes.

Abstract:
Embodiments of invention are directed to the formation of microprobes (i.e. compliant electrical or electronic contact elements) on a temporary substrate, dicing individual probe arrays, and then transferring the arrays to space transformers or other permanent substrates. Some embodiments of the invention transfer probes to permanent substrates prior to separating the probes from a temporary substrate on which the probes were formed while other embodiments do the opposite. Some embodiments, remove sacrificial material prior to transfer while other embodiments remove sacrificial material after transfer. Some embodiments are directed to the bonding of first and second electric components together using one or more solder bumps with enhanced aspect ratios (i.e. height to width ratios) obtained as a result of surrounding the bumps at least in part with rings of a retention material. The retention material may act be a solder mask material.
