摘要： An image sensor improving the uniformity of effective incident light. In one example, the size of microlenses disposed in different regions of the image sensor is changed to balance the brightness in different regions, in which the size of each microlens is a function of the distance between the microlens to the chip center In another example, the distance between the center of the microlens and the center of the corresponding sensing area is changed to balance the brightness in different regions and the corresponding color filters are shifted such that the microlens is overlying a corresponding color filter unit without overlying adjacent regions thereof, in which the distance between the center of the microlens and the center of the corresponding sensing area is a function of the distance between the corresponding sensing area to the chip center.

摘要： A packaged image sensing device of improved sensitivity is formed by providing a mechanism for enhancing the focusing of embedded microlenses on the photosensitive elements of the image sensor. Normally, the bonding material interposed between the packaging layers and the microlenses defocuses the microlenses. In one embodiment of the present invention, the focus is restored by interposing an intermediate optically refractive layer between the bonding material and the lenses. In another embodiment, a bonding material with a lower index of refraction is used. In a final embodiment, the microlenses are formed in a material of a higher index of refraction.

摘要： Within a method for forming an image array optoelectronic microelectronic fabrication there is first provided a substrate. There is then formed at least in part over the substrate a bidirectional array of image array optoelectronic microelectronic pixel elements comprising a plurality of series of patterned color filter layers corresponding with a plurality of colors. Within the method, at least one series of patterned color filter layers within the plurality of series of patterned color filter layers corresponding with at least one color within the plurality of colors is formed employing a photolithographic method which employs a plurality of separate photoexposure steps for forming a plurality of separate sub-series of patterned color filter layers within the series of patterned color filter layers corresponding with the at least one color within the plurality of colors. By employing the plurality of separate photoexposure steps for forming the plurality of separate sub-series of patterned color filter layers within the series of patterned color filter layers corresponding with the at least one color within the plurality of colors, the image array optoelectronic microelectronic fabrication is formed with enhanced resolution.
