Photodiode with different electric potential regions for image sensors
Abstract:
An image sensor pixel is disclosed. The pixel may include a photodiode having a first region with a first potential and a second region with a second, higher potential, with the second region being offset in depth from the first region in a semiconductor chip. A storage node may be positioned at substantially the same depth as the second region of the photodiode. A storage gate may be operable to transfer charge between the photodiode and the storage node.
