  • Patent number: 8664683
    Abstract: A method for providing, on a carrier (40), an insulative spacer layer (26) which is patterned such that a cavity (27) is formed which enables connection of an optical semiconductor element (41) to the intended conductor structure (22) when placed inside the cavity (27). The cavity (27) is formed such that it, through its shape, extension and/or depth, accurately defines a location of an optical element (45; 61) in relation to the optical semiconductor element (41). Through the provision of such a patterned insulative spacer layer, compact and cost-efficient optical semiconductor devices can be mass-produced based on such a carrier without the need for prolonged development or acquisition of new and expensive manufacturing equipment.

  • Patent number: 8658456
    Abstract: A tiltable micro-electro-mechanical (MEMS) system lens comprises a microscopic lens located on a front surface of a semiconductor-on-insulator (SOI) substrate and a semiconductor rim surrounding the periphery of the microscopic lens. Two horizontal semiconductor beams located at different heights are provided within a top semiconductor layer. The microscopic lens may be tilted by applying an electrical bias between the lens rim and one of the two semiconductor beams, thereby altering the path of an optical beam through the microscopic lens. An array of tiltable microscopic lenses may be employed to form a composite lens having a variable focal length may be formed. A design structure for such a tiltable MEMS lens is also provided.

  • Publication number: 20140042579
    Abstract: The present invention relates to an image sensor comprising a microlens array, and to a manufacturing method thereof. The method of the present invention includes gradually increasing the aluminum composition ratio of a compound semiconductor as the latter gradually gets farther from a substrate, to enable a microlens-forming layer to grow, and making the oxidation rate of the region adjacent to the substrate slower and the oxidation rate of the region farther from the substrate faster, making the interface between the oxidized region and the unoxidized region into a lens shape after the completion of oxidation. The thus-made lens is integrated into an image sensor. The present invention reduces costs for manufacturing image sensors in which a microlens is integrated, increases the signal-to-noise ratio and resolution of the image sensor, and achieves improved sensitivity.

    Abstract: A solid state image sensor, a method for fabricating the solid state image sensor and a design structure for fabricating the solid state image sensor structure include a substrate that in turn includes a photosensitive region. Also included within solid state image sensor is a non-planar reflector layer located over a side of the photosensitive region and the substrate opposite an incoming radiation side of the photosensitive region and the substrate. The non-planar reflector layer is shaped and positioned to reflect uncaptured incident radiation back into the photosensitive region while avoiding optical cross-talk with an additional photosensitive region laterally separated within the substrate.
