  • Patent number: 11393866
    Abstract: Various embodiments of the present disclosure are directed towards a method for forming an image sensor in which a device layer has high crystalline quality. According to some embodiments, a hard mask layer is deposited covering a substrate. A first etch is performed into the hard mask layer and the substrate to form a cavity. A second etch is performed to remove crystalline damage from the first etch and to laterally recess the substrate in the cavity so the hard mask layer overhangs the cavity. A sacrificial layer is formed lining cavity, a blanket ion implantation is performed into the substrate through the sacrificial layer, and the sacrificial layer is removed. An interlayer is epitaxially grown lining the cavity and having a top surface underlying the hard mask layer, and a device layer is epitaxially grown filling the cavity over the interlayer.

  • Patent number: 11383195
    Abstract: A device for capturing particles includes a gas-guiding unit, a gas-guiding unit and a mist-elimination unit. The gas-guiding unit has opposing first and second ends. The mist-elimination unit is disposed at the second end. The liquid-circulation unit, disposed under the mist-elimination unit by surrounding the gas-guiding unit, includes through holes below the gas-guiding unit by a gap. A gas containing particles enters the channel via the first end and then the mist-elimination unit via the second end. While the gas flows into the channel, the liquid in the liquid-circulation unit is inhaled into the channel via the gap to form droplets containing particles. After the droplets are captured by the mist-elimination unit, the liquid formed at the mist-elimination unit flows down into the liquid-circulation unit to reform the liquid to be further inhaled back to the channel of the gas-guiding unit via the gap.
