    Abstract: The present disclosure relates to a method of forming an integrated chip. The method includes forming an ILD layer over a memory device over a substrate. A hard mask structure is formed over the ILD layer and a patterning structure is formed over the hard mask structure. The hard mask structure has sidewalls defining a first opening directly over the memory device and centered along a first line perpendicular to an upper surface of the substrate. The patterning structure has sidewalls defining a second opening directly over the memory device and centered along a second line parallel to the first line. The second line is laterally offset from the first line by a non-zero distance. The ILD layer is etched below an overlap of the first and second openings to define a top electrode via hole. The top electrode via hole is with a conductive material.

  • Publication number: 20200203098
    Abstract: A keyboard device includes a base, a wing-type connecting element and a keycap. The base plate includes a close-type connecting bracket. The wing-type connecting element includes a first frame and a second frame. A connecting shaft of the second frame is received within the close-type connecting bracket. Consequently, the wing-type connecting element is connected with the base plate. While the keycap is depressed, the connecting shaft is only allowed to be rotated and limited within the close-type connecting bracket. Since the swinging range of the wing-type connecting element is reduced, the keyboard device of the present invention is capable of improving the depressing stability of the keycap.
