    Abstract: A color image sensor includes a pixel array including a CFA overlaying an array of photo-sensors for acquiring a color image. The CFA includes first color filter elements of a first color overlaying a first group of the photo-sensors, second color filter elements of a second color overlaying a second group of the photo-sensors, and a plurality of filter stacks overlaying a third group of the photo-sensors. The first group generates first color signals of a first color channel and the second group generates second color signals of a second color channel. Each of the filter stacks includes a first stacked filter of the first color and a second stacked filter of the second color. A sensitivity of the filter stacks equals a product of sensitivities of the first and the second stacked filters and the filter stacks generate a third color channel.

    Abstract: A reflective semiconductor device includes integrated circuitry disposed in a semiconductor layer. A first plurality of mirrors is formed in a mirror layer over the semiconductor layer, and each of the first plurality of mirrors is spaced apart from one another by at least a uniform width. A thin dielectric film layer covers sidewalls of the first plurality of mirrors and the semiconductor layer in the regions between the spaced apart first plurality of mirrors. A second plurality of mirrors are formed in the mirror layer between the thin dielectric film layer covered sidewalls of the first plurality of mirrors and over the thin dielectric film layer covering the semiconductor layer. Each one of the first and second plurality of mirrors has the uniform width, and is coupled to the integrated circuitry disposed in the semiconductor layer.

    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.

    Abstract: A method of image sensor package fabrication includes providing an image sensor, including a pixel array disposed in a semiconductor material, and a transparent shield adhered to the semiconductor material. The pixel array is disposed between the semiconductor material and the transparent shield. The method further includes removing portions of the transparent shield to form recessed regions in the transparent shield, where lateral bounds of the transparent shield extend beyond lateral bounds of the pixel array, and wherein the recessed regions are disposed in portions of the transparent shield that extend beyond the lateral bounds of the pixel array. The recessed regions are filled with a light blocking layer.
