Abstract: A three-dimensional integrated circuit (3D-IC) architecture incorporates multiple layers, each layer including at least one die and at least one switch to connect the dies on the different layers. In some aspects, a power distribution network (PDN) is routed from a first layer through the switches to supply power to at least one other layer, thereby reducing routing congestion on the layers. The switches can be placed around the periphery of an IC package to improve heat dissipation (e.g., by improving heat transfer from the center to the edge of the IC package). The switches can be used for routing test signals and/or other signals between layers, thereby improving test functionality and/or fault recovery.

Abstract: Provided are novel methods of fabricating photovoltaic modules using pressure sensitive adhesives (PSA) to secure wire networks of interconnect assemblies to one or both surfaces of photovoltaic cells. A PSA having suitable characteristics is provided near the interface between the wire network and the cell's surface. It may be provided together as part of the interconnect assembly or as a separate component. The interconnect assembly may also include a liner, which may remain as a part of the module or may be removed later. The PSA may be distributed in a void-free manner by applying some heat and/or pressure. The PSA may then be cured by, for example, exposing it to UV radiation to increase its mechanical stability at high temperatures, in particular at a, for example the maximum, operating temperature of the photovoltaic module. For example, the modulus of the PSA may be substantially increased during this curing operation.

Abstract: An improved microfabrication technique for Josephson junctions in superconducting integrated circuits, based on the use of a double-layer lithographic mask for partial anodization of the side-walls and base electrode of the junctions. The top layer of the mask is a resist material, and the bottom layer is a dielectric material chosen so to maximize adhesion between the resist and the underlying superconducting layer, be etch-compatible with the underlying superconducting layer, and be insoluble in the resist and anodization processing chemistries. The superconductor is preferably niobium, under a silicon dioxide layer, with a conventional photoresist or electron-beam resist as the top layer. This combination results in a substantial increase in the fabrication yield of high-density superconducting integrated circuits, increase in junction uniformity and reduction in defect density. A dry etch more compatible with microlithography may be employed.
