    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: A semiconductor structure including a vertical metal-insulator-metal capacitor, and a method for fabricating the semiconductor structure including the vertical metal-insulator-metal capacitor, each use structural components from a dummy metal oxide semiconductor field effect transistor located and formed over an isolation region located over a semiconductor substrate. The dummy metal oxide field effect transistor may be formed simultaneously with a metal oxide semiconductor field effect transistor located over a semiconductor substrate that includes the isolation region. The metal-insulator-metal capacitor uses a gate as a capacitor plate, a uniform thickness gate spacer as a gate dielectric and a contact via as another capacitor plate. The uniform thickness gate spacer may include a conductor layer for enhanced capacitance. A mirrored metal-insulator-metal capacitor structure that uses a single contact via may also be used for enhanced capacitance.

    摘要: A tensile-stress-generating structure is formed above a gate electrode in a CMOS image sensor to apply a normal tensile stress between a charge collection well of a photodiode, which is also a source region of a transfer transistor, and a floating drain in the direction connecting the source region and the floating drain. The tensile stress lowers the potential barrier between the source region and the body of the transfer transistor to effect a faster and more through transfer of the electrical charges in the source region to the floating drain. Image lag is thus reduced in the CMOS image sensor. Further, charge capacity of the source region is also enhanced due to the normal tensile stress applied to the source region.

    摘要: 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.
