Abstract: An image-sensor package includes a cover glass, an image sensor, and an integrated circuit. The cover glass has a cover-glass bottom surface, to which the image sensor is bonded. The integrated circuit is beneath the cover-glass bottom surface, adjacent to the image sensor, and electronically connected to the image sensor. A method for packaging an image sensor includes attaching an image sensor to a cover-glass bottom surface of a cover glass, a light-sensing region of the image sensor facing the cover-glass bottom surface. The method also includes attaching an integrated circuit to the cover-glass bottom surface, a top IC-surface of the integrated circuit facing the cover-glass bottom surface.

Abstract: A curved-surface image-sensor assembly has a porous carrier having a concave surface with a thinned image sensor bonded by an adhesive to its concave surface of the porous carrier; the porous carrier is mounted into a water-resistant package. The sensor assembly is made by fabricating a thinned, flexible, image-sensor integrated circuit (IC) and applying adhesive to a non-illuminated side of the IC; positioning the IC over a concave surface of a porous carrier; applying vacuum through the porous carrier to suck the IC onto the concave surface of the porous carrier; and curing the adhesive to bond the IC to the concave surface of the porous carrier.

Abstract: A chip-scale image sensor package includes a semiconductor substrate, a transparent substrate, a thin film, and a plurality of conductive pads. The semiconductor substrate has (i) a pixel array, and (ii) a peripheral region surrounding the pixel array. The transparent substrate covers the pixel array, has a bottom substrate surface proximate the pixel array, and a top substrate surface opposite the bottom substrate surface. The thin film is on a region of the top substrate surface directly above both (i) the entire pixel array and (ii) a portion of the peripheral region adjacent to the pixel array. Each of the plurality of conductive pads is located within the peripheral region, and is electrically connected to the pixel array. A portion of each of the plurality of conductive pads is not directly beneath the thin film.

Abstract: A cavityless chip-scale image-sensor package includes a substrate, a microlens array, and a low-index layer. The substrate includes a plurality of pixels forming a pixel array. The microlens array includes a plurality of microlenses each (i) having a lens refractive index, (ii) being aligned to a respective one of the plurality of pixels and (iii) having a non-planar microlens surfaces facing away from the respective one of the plurality of pixels. The low-index layer has a first refractive index less than the lens refractive index. The low-index layer also includes a bottom surface, at least part of which is conformal to each non-planar microlens surface. The microlens array is between the pixel array and the low-index layer.

Abstract: A cavity interposer has a cavity, first bondpads adapted to couple to a chip-type camera cube disposed within a base of the cavity at a first level, the first bondpads coupled through feedthroughs to second bondpads at a base of the interposer at a second level; and third bondpads adapted to couple to a light-emitting diode (LED), the third bondpads at a third level. The third bondpads coupled to fourth bondpads at the base of the interposer at the second level; and the second and fourth bondpads couple to conductors of a cable with the first, second, and third level different. An endoscope optical includes the cavity interposer an LED, and a chip-type camera cube electrically bonded to the first bondpads; the LED is bonded to the third bondpads; and a top of the chip-type camera cube and a top of the LED are at a same level.

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.
