  • Publication number: 20230085284
    Abstract: A method for detecting orientation of an integrated circuit is disclosed. The method includes moving, in response to a gravitational force, a mobile metallic piece in an evolution zone of a housing. The housing is formed in an interconnect region of the integrated circuit. The housing includes walls defining the evolution zone. The walls are formed within multiple metallization levels of the interconnect region. The walls include a floor wall and a ceiling wall. At least one of the floor wall and ceiling wall incorporate a pointed element directing its pointed region towards the mobile metallic piece. The pointed element delimits an open crater in a concave part of a projection. The method further includes creating an electrical signal by movement of the mobile metallic piece at a plurality of electrically conducting elements positioned at boundary points of the evolution zone and detecting the electrical signal by a detector.

  • Patent number: 11536872
    Abstract: A method of operating a mechanical switching device is disclosed. The switching device includes a housing, an assembly disposed in the housing, and a body. The assembly is thermally deformable and comprises a beam held in two different places by two arms secured to edges of the housing. The beam is remote from the body in a first configuration and in contact with and immobilized by the body in a second configuration. The assembly has the first configuration at a first temperature and the second configuration when one of the arms has a second temperature different from the first temperature. The method includes exposing an arm of the assembly to the second temperature, and releasing the beam using a release mechanism. The release mechanism includes a pointed element comprising a pointed region directed towards the body. The pointed element limits an open crater in a concave part of a projection.

  • Patent number: 10379254
    Abstract: A method for producing an integrated circuit pointed element is disclosed. An element has a projection with a concave part directing its concavity towards the element. The element includes a first etchable material. A zone is formed around the concave part of the element. The zone includes a second material that is less rapidly etchable than the first material for a particular etchant. The first material and the second material are etched with the particular etchant to form an open crater in the concave part and thus to form a pointed region of the element.

  • Patent number: 8881090
    Abstract: The technological fabrication of the integrated circuit includes a fabrication of the integrated circuit in a reduced technological version of a native technology including at least a first dimensional compensation applied to the reduced channel length and to the reduced channel width of each transistor originating from a transistor, referred to as a “minimum transistor”, designed in the native technology and having in this native technology an initial channel length equal to a minimum length for the native technology and an initial channel width equal to a minimum width for the native technology. The fabrication obtains a transistor having a channel length equal, to a given precision, to the initial channel length and a channel width equal, to a given precision, to the initial channel width.
