  • Patent number: 10964746
    Abstract: Some embodiments of the present disclosure relate to a method in which a functional layer is formed over an upper semiconductor surface of a semiconductor substrate, and a capping layer is formed over the functional layer. A first etchant is used to form a recess through the capping layer and through the functional layer. The recess has a first depth and exposes a portion of the semiconductor substrate there through. A protective layer is formed along a lower surface and inner sidewalls of the recess. A second etchant is used to remove the protective layer from the lower surface of the recess and to extend the recess below the upper semiconductor surface to a second depth to form a deep trench. To prevent etching of the functional layer, the protective layer remains in place along the inner sidewalls of the recess while the second etchant is used.

    Abstract: A human condition detection device comprises a depth image-taking module for taking a depth image of a target area. A millimeter-wave radar module detects breaths or heartbeats in the target area to provide a signal. A thermal image-taking module takes a thermal image of the target area. A processor module determines whether a person is in the target area based on the depth image. The processor module determines whether there is any breath or heartbeat based on the signal if a person is in the target area. The processor module determines whether there is any abnormal vital sign of the person in the target area based on the signal and the thermal image if there is a breath or heartbeat in the target area. The processor module actuates the warning module to provide a warning if there is an abnormal vital sign of the person in the target area.

  • Publication number: 20200358400
    Abstract: A multi-stage amplifier with a high signal-to-noise ratio is introduced. Multiple amplification stages are cascaded between an input terminal and an output terminal of the amplifier. A controller switches the output stage among the multiple amplification stages from a normal mode to an attenuation mode in response to the amplifier input being lower than the threshold. In the attenuation mode, the output stage provides an attenuation resistor coupled in series with the load resistor of the amplifier. Noise is successfully attenuated by the attenuation-mode output stage.
