  • Patent number: 11751485
    Abstract: Various embodiments of the present application are directed towards a method for forming a flat via top surface for memory, as well as an integrated circuit (IC) resulting from the method. In some embodiments, an etch is performed into a dielectric layer to form an opening. A liner layer is formed covering the dielectric layer and lining the opening. A lower body layer is formed covering the dielectric layer and filling a remainder of the opening over the liner layer. A top surface of the lower body layer and a top surface of the liner layer are recessed to below a top surface of the dielectric layer to partially clear the opening. A homogeneous upper body layer is formed covering the dielectric layer and partially filling the opening. A planarization is performed into the homogeneous upper body layer until the dielectric layer is reached.

  • Publication number: 20230268148
    Abstract: An operation apparatus for a rotary switch and a rotary switch relate to the field of switch technologies. The operation apparatus for a rotary switch includes a motion member and a fastener having an accommodating cavity. The motion member passes through the accommodating cavity, and the motion member is driven to move in the accommodating cavity and can be switched between a lock position and a working position. The lock position restricts rotation of the motion member. When the motion member is in the working position, a release can be reset under action of the motion member. The operation apparatus for the rotary switch provides for reliable reset of the release.
