    Abstract: A method for manufacturing a pixel sensor cell that includes a photosensitive element having a non-laterally disposed charge collection region. The method includes forming a trench recess in a substrate of a first conductivity type material, and filling the trench recess with a material having second conductivity type material. The second conductivity type material is then diffused out of the filled trench material to the substrate region surrounding the trench to form the non-laterally disposed charge collection region. The filled trench material is removed to provide a trench recess, and the trench recess is filled with a material having a first conductivity type material. A surface implant layer is formed at either side of the trench having a first conductivity type material. A collection region of a trench-type photosensitive element is formed of the outdiffused second conductivity type material and is isolated from the substrate surface.

A design structure for a pixel sensor cell having reduced complexity includes an n-type collection well region formed beneath a surface of a substrate for collecting electrons generated by electromagnetic radiation impinging on the pixel sensor cell and a p-type collection well region formed beneath the surface of the substrate for collecting holes generated by the impinging photons. A circuit structure having a first input is coupled to the n-type collection well region and a second input is coupled to the p-type collection well region, wherein an output signal of the pixel sensor cell is the magnitude of the difference of a signal of the first input and a signal of the second input.

    Abstract: Disclosed are embodiments of a method for randomly personalizing chips during fabrication, a personalized chip structure and a design structure for such a personalized chip structure. The embodiments use electronic device design and manufacturing processes to randomly or pseudo-randomly create a specific variation in one or more instances of a particular electronic device formed on each chip. The device design and manufacturing processes are tuned so that the specific variation occurs with some predetermined probability, resulting in a desired hardware distribution and personalizing each chip. The resulting personalized chips can be used for modal distribution of chips. For example, chips can be personalized to allow sorting when a single chip design can be used to support multiple applications. The resulting personalized chips can also be used for random number generation for creating unique on-chip identifiers, private keys, etc.

    Abstract: A CMOS image sensor and method of fabrication wherein the sensor includes Copper (Cu) metallization levels allowing for incorporation of a thinner interlevel dielectric stack to result in a pixel array exhibiting increased light sensitivity. The CMOS image sensor includes structures having a minimum thickness of barrier layer metal that traverses the optical path of each pixel in the sensor array or, that have portions of barrier layer metal selectively removed from the optical paths of each pixel, thereby minimizing reflectance. That is, by implementing various block or single mask methodologies, portions of the barrier layer metal are completely removed at locations of the optical path for each pixel in the array. In a further embodiment, the barrier metal layer may be formed atop the Cu metallization by a self-aligned deposition.

    Abstract: A CMOS image sensor array and method of fabrication wherein the sensor includes Copper (Cu) metallization levels allowing for incorporation of a thinner interlevel dielectric stack with improved thickness uniformity to result in a pixel array exhibiting increased light sensitivity. In the sensor array, each Cu metallization level includes a Cu metal wire structure formed at locations between each array pixel and, a barrier material layer is formed on top each Cu metal wire structure that traverses the pixel optical path. By implementing a single mask or self-aligned mask methodology, a single etch is conducted to completely remove the interlevel dielectric and barrier layers that traverse the optical path. The etched opening is then refilled with dielectric material. Prior to depositing the refill dielectric, a layer of either reflective or absorptive material is formed along the sidewalls of the etched opening to improve sensitivity of the pixels by either reflecting light to the underlying photodiode or by eliminating light reflections.
