The method then includes applying wax into the second channel, and sawing through the optically transparent wafer and through at least a portion of the interposer wafer to form a third channel having a width that is wider than a width of the second channel. The wax is then removed to expose a portion of the first surface of the semiconductor wafer.

  • Patent number: 11143847
    Abstract: A compact, small form factor optical system for cameras that provides multiple optical paths to capture images of an object field in different portions of the light spectrum. The optical system includes a front lens group that captures visible and near-infrared (NIR) light from an object field and refracts the light to a beam splitter that splits the visible light and the NIR light onto two paths. On the visible light path, a visible light lens group refracts the visible light to form an image of the object field at a visible light sensor. On the NIR light path, a NIR light lens group refracts the NIR light to form an image of the object field at an NIR light sensor. The optical system thus provides images of the object field at two sensor planes, one image in the visible spectrum and the other image in the NIR spectrum.

  • Patent number: 11131721
    Abstract: The semiconductor device includes a Hall element, a first differential pair, a second differential pair, an output amplifier circuit, and a voltage divider circuit. The Hall element outputs a signal that is dependent on stress to be applied to a semiconductor substrate to the first differential pair. The voltage divider circuit divides a voltage into a divided voltage having a voltage dividing ratio that is dependent on the stress. The first differential pair outputs a first current based on the signal. The second differential pair outputs a second current based on the divided voltage and a reference voltage. The output amplifier circuit outputs a voltage based on the first and second currents. A gain of the output amplifier circuit is approximated by a sum of a difference between stress dependence coefficients of transconductances of the first and second differential pairs and a stress dependence coefficient of the voltage dividing ratio.
