    Abstract: A method and apparatus for employing a light shield to modulate pixel color responsivity. The improved pixel includes a substrate having a photodiode with a light receiving area. A color filter array material of a first color is disposed above the substrate. The pixel has a first relative responsivity. A light shield is disposed above the substrate to modulate the pixel color responsivity. The light shield forms an aperture whose area is substantially equal to the light receiving area adjusted by a reduction factor. The reduction factor is the result of an arithmetic operation between the first relative responsivity and a second relative responsivity, associated with a second pixel of a second color.

    Abstract: CMOS pixel sensors have been of interest as replacements for CCD's in imaging applications. Such devices promise lower power and simpler system level design through fewer power supply voltages and higher functional integration. It is difficult and cost ineffective to utilize images to test active pixel sensors. Here, a method and apparatus for electrical testing of CMOS pixel sensors is described which involves electrically writing a pattern into the CMOS pixel sensors for the detection of adjacent cell shorts or stuck at faults as well as verification of read-channel circuit functionality and performance. The invention provides for an electrical testing of CMOS pixel array that is simple, time efficient and cost effective for use in, for example, production.

    Abstract: What is disclosed is an apparatus for reducing row reset noise in photodiode based complementary metal oxide (CMOS) sensors. The apparatus uses at least one reference pixel for each row of pixels in a sensor array. Also, a reset noise elimination unit is provided to adjust the values received from the pixels in a particular row by an adjustment value determined from the reset values received from the reference pixels. Additionally, a method of using the apparatus is disclosed. The method has a step of providing a first reset signal to a row of pixels including the reference pixels. The method also reads out a first set of values from this row after integration. The method continues with providing a second reset signal to the row and a second set of values is read from the row. An adjustment value is calculated from the difference of the values which are read out from the reference pixels.

    Abstract: An image sensor having a well-to-substrate diode as the photodetector. In a preferred embodiment, a modern salicided (CMOS) process is utilized to manufacture the image sensor. The field oxide region above the diode junction is transparent to visible light, thus allowing the photodiode competitive quantum efficiency as compared to devices having source/drain diffusion-to-substrate photodiodes fabricated on a non-salicided process. The photodiode can be integrated as part of a sensor array with digital circuitry using a relatively unmodified digital CMOS process. Furthermore, the structure allows the optical properties of the photodiode to be engineered by modifying the well without deleterious effects, to approximate a first order, on the characteristics of a FET built in another identical well.
