    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： 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 method for forming an image sensor device. An alignment mark is formed on or in a substrate with distance from the alignment mark to the substrate edge less than about 3 mm. An array of active photosensing pixels is formed on the substrate. At least one dielectric layer is formed covering the substrate and the array. A color filter photoresist is formed on the least one dielectric layer. Subsequent to removal of the color filter photoresist from the alignment mark, the color filter photoresist is exposed with alignment to the alignment mark.
