    Abstract: In some embodiments, the present disclosure relates to an integrated chip including a gate electrode over a substrate. A pair of source/drain regions are disposed in the substrate on opposing sides of the gate electrode. A dielectric layer is over the substrate. An etch stop layer is between the gate electrode and the dielectric layer. A gate capping layer overlies the gate electrode, continuously extends from a top surface of the etch stop layer to a top surface of the gate electrode, and comprises a curved sidewall over the top surface of the etch stop layer. A conductive contact overlies an individual source/drain region. A width of the conductive contact continuously decreases from a top surface of the conductive contact to a first point disposed above a lower surface of the gate capping layer.

  • Patent number: 11940610
    Abstract: An autofocus system includes a focus light source, an objective lens, a defocus lens, a first image sensor, and a controller. The defocus lens is disposed on the transmission path of the focus light beam, so that a minimum light point of the focus light beam passing through the objective lens deviates from a focus of the objective lens. The first image sensor is configured to receive a focus reflected light beam generated after the focus light beam is reflected by the sample. The controller is electrically connected to the first image sensor. According to a center change of gravity, a position change, or an energy change of a light spot formed by the focus reflected light beam on an image plane of the first image sensor, the controller drives the objective lens or the sample to move, so that the focus of the objective lens falls on the sample.

    Abstract: A reflector unit may behave as a retroreflector to reflect light of a selected color. The reflector unit may comprise a first reflector having a first color, a second reflector having a second color, and a mask that either allows incoming light to reach the first reflector and not the second reflector or allows incoming light to reach the second reflector and not the first reflector. An active light unit may emit light of a particular color in response to receiving light. In this fashion, the active light unit may simulate the operation of a reflector. The reflector unit and the active light unit may operate on a bi-directional vehicle.
