  • Publication number: 20240071812
    Abstract: A method for forming a semiconductor device includes providing a semiconductor substrate, implanting n-type impurities into a device region in the semiconductor substrate to form an implanted region and an un-implanted region. The method also includes forming an epitaxial layer on the semiconductor substrate and forming a trench surrounding the device region in direct contact with the implanted region. The method further includes performing a selective lateral etch through the trench to remove the implanted region to form a cavity under the epitaxial layer. The un-implanted region is retained to form a pillar under the epitaxial layer. Next, an insulating material is disposed in the cavity and the trench. The method forms a single crystalline region that is separated from the semiconductor substrate by the insulating material except at the pillar.

  • Patent number: 9969460
    Abstract: A bicycle pedal includes a body having a fixed member, a movable member, a resilient unit and a link respectively connected to each of a first face and a second face thereof. The link and the resilient unit are respectively located on inside of the movable member. The link contacts the movable member. When the cleat of a bicycle shoe pushes the movable member and the link away from the body, the push end of the link swings away from the body and pushes the cleat to disengage from the peal. The link has a restriction portion located corresponding to outside of the end piece. The restriction portion extends from the link and toward the end piece to prevent the bolt from dropping from the end piece.
