    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: The present invention relates to semiconductor-on-insulator (SOI) substrate structures that contain surface semiconductor regions of different crystal orientations located directly on an insulator layer. The present invention also relates to methods for fabricating such SOI substrate structures, by growing an insulator layer directly on a multi-orientation bulk semiconductor substrate that comprises surface semiconductor regions of different crystal orientations located directly on a semiconductor base layer, and removing the semiconductor base layer, thereby forming a multi-orientation SOI substrate structure that comprises surface semiconductor regions of different crystal orientations located directly on the insulator layer.

    Abstract: An interconnect layout, an image sensor including the interconnect layout and a method for fabricating the image sensor each use a first electrically active physical interconnect layout pattern within an active pixel region and a second electrically active physical interconnect layout pattern spatially different than the first electrically active physical interconnect layout pattern within a dark pixel region. The second electrically active physical interconnect layout pattern includes at least one electrically active interconnect layer interposed between a light shield layer and a photosensor region aligned therebeneath, thus generally providing a higher wiring density. The higher wiring density within the second layout pattern provides that that the image sensor may be fabricated with enhanced manufacturing efficiency and a reduction of metallization levels.

    Abstract: A novel pixel 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. An isolation structure is formed adjacent to the photosensitive device pinning layer. The isolation structure includes a dopant region comprising material of the first conductivity type selectively formed along a sidewall of the isolation structure that is adapted to electrically couple the surface pinning layer to the underlying substrate. The corresponding method for forming the dopant region selectively formed along the sidewall of the isolation structure comprises an out-diffusion process whereby dopant materials present in a doped material layer formed along selected portions in the isolation structure are driven into the underlying substrate during an anneal. Alternately, or in conjunction, an angled ion implantation of dopant material in the isolation structure sidewall may be performed by first fabricating a photoresist layer and reducing its size by removing a corner, or a corner portion thereof, which may block the angled implant material.

    Abstract: The image qualify of an image frame from a CMOS image sensor array operated in global shutter mode may be enhanced by dispersing or randomizing the noise introduced by leakage currents from floating drains among the rows of the image frame. Further, the image quality may be improved by accounting for time dependent changes in the output of dark pixels in dark pixel rows or dark pixel columns. In addition, voltage and time dependent changes in the output of dark pixels may also be measured to provide an accurate estimate of the noise introduced to the charge held in the floating drains. Such methods may be employed individually or in combination to improve the quality of the image.
