    Abstract: A keyswitch module includes a bottom plate, a movable plate, a keycap, and a connecting assembly. The moving plate is stacked with the bottom plate and capable of moving between a first position and a second position relative to the bottom plate. The movable plate moves a horizontal stroke from the first position to the second position. The connecting assembly is operatively connected to the bottom plate and connected to the keycap. A forced portion of the connecting assembly is configured to be moved by a forcing structure of the movable plate to make the keycap move between an opening position and a closing position relative to the bottom plate. When the movable plate is located at the first position, the forcing structure and the forced portion are separated by a distance, and the keycap is located at the opening position.

  • Publication number: 20160027903
    Abstract: A method includes etching a semiconductor substrate to form a semiconductor strip and trenches on opposite sidewalls of the semiconductor strip. A spacer is formed on a sidewall of the semiconductor strip which is used as an etching mask to extend the trenches down into the semiconductor substrate. A dielectric material is filled into the trenches and then planarized to form insulation regions in the trenches. The insulation regions are recessed. After the recessing, top surfaces of the insulation regions are lower than a top surface of the semiconductor strip and a gate structure may be formed thereon.
