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 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： A pixel for an image sensor includes a photosensor located within a substrate. A patterned dielectric layer having an aperture registered with the photosensor is located over the substrate. A lens structure is located over the dielectric layer and also registered with the photosensor. A liner layer is located contiguously upon a top surface of the dielectric layer, and the sidewalls and bottom of the aperture. The liner layer provides for enhanced reflection for off-axis incoming light and enhanced capture thereof by the photosensor. When the aperture does not provide a dielectric layer border for a metallization layer embedded within the dielectric layer, an exposed edge of the metallization layer may be chamfered.

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 novel image sensor structure formed on a substrate of a first conductivity type includes a photosensitive device of a second conductivity type and a surface pinning layer of the first conductivity type. A trench isolation region is formed adjacent to the photosensitive device pinning layer. The structure includes a dopant region comprising material of the first conductivity type formed along a sidewall of the isolation region that is adapted to electrically couple the pinning layer to the substrate. The corresponding method facilitates an angled ion implantation of dopant material in the isolation region sidewall by first fabricating the photoresist layer and reducing its size by removing a corner, or a corner portion thereof, which may block the angled implant material. To facilitate the angled implant to the sidewall edge past resist block masks, two methods are proposed: 1) a spacer type etch of the imaged photoresist; or, 2) a corner sputter process of the imaged photoresist.
