Image sensors with optically black pixels
Publication/Patent Number: US10165211B1 Publication Date: 2018-12-25 Application Number: 15/683,201 Filing Date: 2017-08-22 Inventor: Borthakur, Swarnal   Ford loriston   Banachowicz, Bartosz Piotr   Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLC   IPC: H04N5/369 Abstract: An image sensor may include optically black pixels for obtaining dark current measurements. The image sensor may include dummy pixels between the active pixel array and the optically black pixels. Light incident upon the dummy pixels may be redirected to the optically black pixels, causing inaccurate dark current measurements. Light-blocking structures may be provided in the dummy pixels to prevent light from reaching the optically black pixels. A grid of openings may be formed in the active pixel array and the dummy pixel area. The grid may be filled with color filters in the active area and light-blocking elements in the dummy pixel area. The dummy pixel area may include a single opening in the grid in which a single light-blocking element that covers multiple dummy pixel photodiodes is formed. Light-blocking structures in the dummy pixel area may extend over the optically black pixels.

LAYERED LENS STRUCTURES AND METHODS OF PRODUCTION
Publication/Patent Number: US2011180695A1 Publication Date: 2011-07-28 Application Number: 13/082,549 Filing Date: 2011-04-08 Inventor: Li, Jin   Li, Jiutao   Boettiger, Ulrich   Ford loriston   Assignee: ROUND ROCK RESEARCH, LLC   IPC: H01J40/14 Abstract: A microlens structure includes lower lens layers on a substrate. A sputtered layer of glass, such as silicon oxide, is applied over the lower lens layers at an angle away from normal to form upper lens layers that increase the effective focal length of the microlens structure. The upper lens layers can be deposited in an aspherical shape with radii of curvature longer than the lower lens layers. As a result, small microlenses can be provided with longer focal length. The microlenses are arranged in arrays for use in imaging devices.
