  • Patent number: 11784207
    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. A photodetector is formed in the device layer.

  • Patent number: 11778874
    Abstract: An electronic device may include a display having display pixels formed in an active area of the display. The display further includes display driver circuitry for driving gate lines that are routed across the display. A hole such as a through hole, optical window, or other inactive region may be formed within the active area of the display. Multiple gate lines carrying the same signal may be merged together prior to being routed around the hole to help minimize the routing line congestion around the border of the hole. Dummy circuits may be coupled to the merged segment portion to help increase the parasitic loading on the merged segments. The hole may have a tapered shape to help maximize the size of the active area. The hole may have an asymmetric shape to accommodate multiple sub-display sensor components.
