    摘要: An 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 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.

    摘要: An 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.

    摘要: An imaging sensor with an array of FET pixels and method of forming the imaging sensor. Each pixel is a semiconductor island, e.g., N-type silicon on a Silicon on insulator (SOI) wafer. FETs are formed in one photodiode electrode, e.g., a P-well cathode. A color filter may be attached to an opposite surface of island. A protective layer (e.g., glass or quartz) or window is fixed to the pixel array at the color filters. The image sensor may be illuminated from the backside with cell wiring above the cell. So, an optical signal passes through the protective layer is filtered by the color filters and selectively sensed by a corresponding photo-sensor.
