1. An image sensor comprising:
- a substrate including a plurality of photodetector regions, the plurality of photodetector regions collectively defining at least part of a pixel area parallel to a surface of the substrate; and
a shutter trigger contact coupled to provide a common shutter trigger signal to the plurality of photodetector regions, the shutter trigger contact including a contiguous conductive region disposed on the substrate so as to be substantially coextensive with the pixel area.

Abstract
An image sensor comprising a substrate that includes a plurality of photodiodes and a shutter trigger contact is disclosed. The plurality of photodiodes collectively define at least part of a pixel area parallel to a surface of the substrate. The shutter trigger contact is coupled to provide a common shutter trigger signal to the plurality of photodiodes and includes a contiguous conductive region disposed on the substrate substantially coextensively with the pixel area.

14. An image sensor comprising:
-
a substrate including a plurality of photodiodes including at least 25,000 photodiodes, the at least 25,000 photodiodes collectively defining at least part of a pixel area parallel to a surface of the substrate; and a shutter trigger contact coupled to provide a common shutter trigger signal to the plurality of photodiodes, the shutter trigger contact including a contiguous conductive layer disposed on the substrate so that a minimum distance between the shutter trigger contact and each of the plurality of photodiodes is substantially equal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
