    Abstract: A semiconductor die including a semiconductor chip and a test structure, located in a scribe area, is designed and manufactured. The test structure includes an array of complementary metal oxide semiconductor (CMOS) image sensors that are of the same type as CMOS image sensors employed in another array in the semiconductor chip and having a larger array size. Such a test structure is provided in a design phase by providing a design structure in which the orientations of the CMOS image sensors match between the two arrays. The test structure provides effective and accurate monitoring of manufacturing processes through in-line testing before a final test on the semiconductor chip.

    Abstract: A global shutter compatible pixel circuit comprising a reset gate (RG) transistor is provided in which a dynamic voltage is applied to the drain of the reset gate transistor in order to reduce a floating diffusion (FD) leakage therethrough during signal hold time. The drain voltage of the reset gate transistor is held at a lower voltage than a circuit supply voltage to minimize the off-state leakage through the RG transistor, thus reducing the change in the voltage at the floating diffusion during the signal hold time. In addition, a design structure for such a circuit providing a dynamic voltage to the drain of a reset gate of a pixel circuit is also provided.

    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.
