    Abstract: An active-pixel device assembly with stray-light reduction includes an active-pixel device including a semiconductor substrate and an array of active pixels, a light-transmissive substrate disposed on a light-receiving side of the active-pixel device, and a rough opaque coating disposed on a first surface of the light-transmissive substrate and forming an aperture aligned with the array of active pixels, wherein the rough opaque coating is rough so as to suppress reflection of light incident thereon from at least one side. A method for manufacturing a stray-light-reducing coating for an active-pixel device assembly includes depositing an opaque coating on a light-transmissive substrate such that the opaque coating forms a light-transmissive aperture, and roughening the opaque coating to form a rough opaque coating, said roughening including treating the opaque coating with an alkaline solution.

    Abstract: A liquid crystal display device includes a first substrate, a pixel array formed on the first substrate, a transparent substrate, a liquid crystal layer disposed between the pixel array and the transparent substrate, a transparent electrode disposed between the transparent substrate and the liquid crystal layer, and an input electrode. The transparent electrode has a longer first edge and an orthogonal shorter second edge. The input electrode extends along, and is electrically coupled along, the first edge of the transparent electrode and has lower impedance than a portion of the transparent electrode overlying the pixel array. The input electrode can include additional portion(s) that extend along, and that are electrically-coupled along, the other edges of the transparent electrode. The input electrode reduces the common voltage propagation delay across the transparent electrode and improves reduces intensity variation over the display area, even for high-frequency common voltage waveforms.

    Abstract: An aerogel-encapsulated image sensor includes a device die with an image sensor fabricated thereon and an aerogel layer that encapsulates the image sensor. A method for encapsulating image sensor pixel arrays of respective bare image sensors formed on a sensor array sheet may include injecting an uncured aerogel portion on each image sensor pixel array, and curing each uncured aerogel portion. The step of curing may include at least one of (a) super-critical drying, (b) surface-modification drying, and (c) pinhole drying an uncured aerogel portion. The method may further include singulating the sensor array sheet into a plurality of aerogel-encapsulated image sensors. A method for encapsulating image sensor pixel arrays of respective bare image sensors on a device wafer may include forming an aerogel layer on each bare image sensor. The step of forming may include at least one of spin-coating, dip-coating, and spray-coating the aerogel layer.

    Abstract: A liquid crystal on silicon (LCOS) panel is provided that includes an electrical contact layer deposited in a pattern on a portion of a transparent conductive layer. An alignment layer protects the conductive layer and electrical contact layer during LCOS panel assembly. The alignment layer is etched away to expose the electrical contact, which protects the underlying conductive layer from the etching process. The resulting LCOS panel has more reliably formed electrical contacts for improved stability of electrical connections to the conductive layer. A method for forming an electrical contact layer on a conductive layer of a LCOS panel includes steps for depositing a patterned layer on a portion of the conductive layer. The method is compatible with microfabrication techniques for scalable manufacturing. The resulting LCOS panel includes a pattern of one or more electrical contacts exposed on a portion of the conductive layer.
