  • Publication number: 20200062587
    Abstract: A semiconductor arrangement and method of formation are provided. The semiconductor arrangement includes a MEMS device in a MEMS area, where a first metal layer is connected to a first metal connect adjacent the MEMS area and a cap is over the MEMS area to vacuum seal the MEMS area. A first wafer portion is over and bonded to the first metal layer which connects the first metal connect to a first I/O port using metal routing. The first metal layer and the first wafer portion bond requires 10% less bonding area than a bond not including the first metal layer. The semiconductor arrangement including the first metal layer has increased conductivity and requires less processing than an arrangement that requires a dopant implant to connect a first metal connect to a first I/O port and has a better vacuum seal due to a reduction in outgassing.

  • Patent number: 10566377
    Abstract: An image sensor includes a substrate, a plurality of light sensitive pixels, a first plurality of color filters, a plurality of reflective sidewalls, and a second plurality of color filters. The light sensitive pixels are formed on said substrate. The first plurality of color filters is disposed over a first group of the light sensitive pixels. The reflective sidewalls are formed on each side of each of the first plurality of color filters. The second plurality of color filters are disposed over a second group of light sensitive pixels and each color filter of the second plurality of color filters is separated from each adjacent filter of said first plurality of color filters by one of the reflective sidewalls. In a particular embodiment an etch-resistant layer is disposed over the first plurality of color filters and the second group of light sensitive pixels.

  • Patent number: 10481439
    Abstract: A liquid crystal display includes a display area and a border area at least partially surrounding the display area, where the display area displays images for viewing and the border area displays display-protection images, which are used to control ion migration in the liquid crystal layer. In a more particular embodiment, the border area displays a series of checkerboard pattern(s), where the checkerboard patterns can alternate between initial and inverted values. The display-protection images protect the liquid crystal display from migrating ions accumulating in particular regions of the pixel array and causing permanent defects in the display area. A liquid crystal display that includes a liquid crystal alignment layer having a plurality of liquid crystal alignment directions is also disclosed. The customized liquid crystal alignment director(s) over the border area promote ion migration away from the display area.

  • Patent number: 10462433
    Abstract: An image sensor includes a substrate, a first set of sensor pixels formed on the substrate, and a second set of sensor pixels formed on the substrate. The sensor pixels of the first set are arranged in rows and columns and are configured to detect light within a first range of wavelengths (e.g., white light). The sensor pixels of the second set are arranged in rows and columns and are each configured to detect light within one of a set of ranges of wavelengths (e.g., red, green, and blue). Each range of wavelengths of the set of ranges of wavelengths is a subrange of said first range of wavelengths, and each pixel of the second set of pixels is smaller than each pixel of the first set of pixels.

  • Patent number: 10204951
    Abstract: A multi-color HDR image sensor includes at least a first combination color pixel with a first color filter and an adjacent second combination color pixel with a second color filter which is different from the first color filter, wherein each combination color pixel includes at least two sub-pixels having at least two adjacent photodiodes. Within each combination color pixel, there is a dielectric deep trench isolation (d-DTI) structure to isolate the two adjacent photodiodes of the two adjacent sub-pixels with same color filters in order to prevent the electrical cross talk. Between two adjacent combination color pixels with different color filters, there is a hybrid deep trench isolation (h-DTI) structure to isolate two adjacent photodiodes of two adjacent sub-pixels with different color filters in order to prevent both optical and electrical cross talk. Each combination color pixel is enclosed on all sides by the hybrid deep trench isolation (h-DTI) structure.
