    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.

    Abstract: A method for fabricating a sealed-sidewall device die may include filling grooves of a deeply-grooved device wafer with a sealant, yielding a sealed grooved device wafer. The method may also include forming grooves in a device wafer to yield the deeply-grooved device wafer. The step of forming grooves may include forming a groove that at least partially penetrates each layer of the device wafer. The method may further include masking each device of the deeply-grooved device wafer. A sealed-sidewall device die may include at least one layer including a device substrate layer, a sidewall including a respective surface of each layer of the at least one layer, a sidewall sealant covering the sidewall, and a device formed on the device substrate layer. The sidewall sealant optionally does not cover a top surface of the device. The top surface of the device may directly adjoin an ambient medium thereabove.
