    摘要: The subject invention is directed to use of photoconductors as conductors of light to photo diodes in a CMOS chip, wherein said photoconductors are separated by at least one low refractive index material (i.e. air). The present invention offers advantages over previous CMOS imaging technology, including enhanced light transmission to photo diodes. The instant methods for producing a CMOS imaging device and CMOS imager system involve minimal power loss. Since no lens is required, the invention eliminates concerns about radius limitation and about damaging lenses during die attach, backgrind, and mount. The invention also provides little or no cross talk between photo diodes.

    摘要: An improved image sensor wherein a first micro-lens array comprised of one or more micro-lenses is positioned over a cavity such that incoming light is focused on the photo sensors of the image sensor. The first micro-lens array may collimate and focus incoming light onto the photo sensors of the image sensor, or may collimate incoming light and direct it to a second micro-lens array which then focuses the light onto the photo sensors. A method of fabricating the improved image sensor is also provided wherein the cavity and first micro-lens array are formed by use of a sacrificial material.
