摘要： A CMOS image sensor array and method of fabrication. The CMOS imager sensor array comprises a substrate; an array of light receiving pixel structures formed above the substrate, the array having formed therein “m” levels of conductive structures, each level formed in a corresponding interlevel dielectric material layer; a dense logic wiring region formed adjacent to the array of light receiving pixel structures having “n” levels of conductive structures, each level formed in a corresponding interlevel dielectric material layer, where n>m. A microlens array having microlenses and color filters formed above the interlevel dielectric material layer, a microlens and respective color filter in alignment with a respective light receiving structure formed at a surface of the substrate. A top surface of the interlevel dielectric material layer beneath the microlens array is recessed from a top surface of the interlevel dielectric material layers of the dense logic wiring region.

摘要： An imaging system for use in a digital camera or cell phone utilizes one chip for logic and one chip for image processing. The chips are interconnected using around-the-edge or through via conductors extending from bond pads on the active surface of the imaging chip to backside metallurgy on the imaging chip. The backside metallurgy of the imaging chip is connected to metallurgy on the active surface of the logic chip using an array of solder bumps in BGA fashion. The interconnection arrangement provides a CSP which matches the space constraints of a cell phone, for example. The arrangement also utilizes minimal wire lengths for reduced noise. Connection of the CSP to a carrier package may be either by conductive through vias or wire bonding. The CSP is such that the imaging chip may readily be mounted across an aperture in the wall of a cell phone, for example, so as to expose the light sensitive pixels on the active surface of said imaging chip to light.

摘要： 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.

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.
