  • Patent number: 12142527
    Abstract: Speed of plasma etching is regulated in regions prone to over-etching by providing an etch resistant structure, such as a metal saw bow, in the region. By adjusting dimensions, such as the length and width of the saw bow legs and an area defined by the saw bow legs, as well as a shape of the etch region through techniques such as chamfering, plasma etch speed in the region can be controlled with an intent to match the speed of etching in non-over-etched regions.

  • Patent number: 12041864
    Abstract: Surface supported quantum wells with a confined surface state capture and stably confine neutral atoms and molecules in a nanometer precise environment. Depending on the physico-chemical conditions in the capturing process, the degree of occupancy, the temperature of the solid substrate, and/or the history of external stimuli like electromagnetic field pulses, these atoms, molecules or clusters assume unique configurations. The atoms or molecules are able to remain coupled to the quantum-well specific electronic state in the confinement and as such exhibit local and delocalized quantum entanglement. The capturing potential arises from the superposition of Pauli repulsion between the captured object and the quantum well-specific confined electronic state. This occurs within on-surface atomic or supramolecular assemblies or surface supported coordination or covalent networks.
