  • Patent number: 11145539
    Abstract: The present disclosure describes a fabrication method that can form air-gaps in shallow trench isolation structures (STI) structures. For example, the method includes patterning a semiconductor layer over a substrate to form semiconductor islands and oxidizing the sidewall surfaces of the semiconductor islands to form first liners on the sidewall surfaces. Further, the method includes depositing a second liner over the first liners and the substrate and depositing a first dielectric layer between the semiconductor islands. The second liner between the first dielectric layer and the first liners is removed to form openings between the first dielectric layer and the first liners. A second dielectric layer is deposited over the first dielectric layer to enclose the openings and form air-gaps between the first dielectric layer and the first liners so that the gaps are positioned along the first liners.

  • Patent number: 11121302
    Abstract: A method for bonding two superconducting integrated circuits (“chips”), such that the bonds electrically interconnect the chips. A plurality of indium-coated metallic posts may be deposited on each chip. The indium bumps are aligned and compressed with moderate pressure at a temperature at which the indium is deformable but not molten, forming fully superconducting connections between the two chips when the indium is cooled down to the superconducting state. An anti-diffusion layer may be applied below the indium bumps to block reaction with underlying layers. The method is scalable to a large number of small contacts on the wafer scale, and may be used to manufacture a multi-chip module comprising a plurality of chips on a common carrier. Superconducting classical and quantum computers and superconducting sensor arrays may be packaged.
