  • Patent number: 9543356
    Abstract: CMOS image sensor pixel sensor cells, methods for fabricating the pixel sensor cells and design structures for fabricating the pixel sensor cells are designed to allow for back side illumination in global shutter mode by providing light shielding from back side illumination of at least one transistor within the pixel sensor cells. In a first particular generalized embodiment, a light shielding layer is located and formed interposed between a first semiconductor layer that includes a photoactive region and a second semiconductor layer that includes the at least a second transistor, or a floating diffusion, that is shielded by the light blocking layer. In a second generalized embodiment, a thin film transistor and a metal-insulator-metal capacitor are used in place of a floating diffusion, and located shielded in a dielectric isolated metallization stack over a carrier substrate.

  • Publication number: 20080108170
    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.

  • Publication number: 20070262305
    Abstract: A semiconductor integrated circuit wafer containing a plurality of integrated circuit chips and having a common substrate, each chip formed with an internal region in the interior of the chip and a removable external region on the perimeter of the internal region and circuitry disposed preferably in the external region and connected to at least one pad of an integrated circuit chip and the wafer substrate to establish electrical connection during electrostatic discharge and prevent ESD damage. The pad and substrate are isolated during tested of the integrated circuit chips in the wafer. Preferably, the external region is removed when the integrated circuit chips are diced from the wafer.

  • Publication number: 20070194397
    Abstract: 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.
