Beschreibung
Zusammenfassung:	An image sensor including a photodiode, a first doped region, a second doped region, a first storage node, a second storage node, a first vertical transfer gate, and a second vertical transfer gate is presented. The photodiode is disposed in a semiconductor material to convert image light to an electric signal. The first doped region and the second doped region are disposed in the semiconductor material between a first side of the semiconductor material and the photodiode. The first doped region is positioned between the first storage node and the second storage node while the second doped region is positioned between the second storage node and the first doped region. The vertical transfer gates are coupled between the photodiode to transfer the electric signal from the photodiode to a respective one of the storage nodes in response to a signal.
