Sony has unveiled a new type of stacked CMOS sensor that uses "two-layer transistor pixels" to double the light gathering capability. Typical image sensors have the light-sensitive photodiodes and pixel transistors that control and amplify the signal on the same layer. However, the new design puts the photodiodes on top and the pixel transistors below, "approximately doubling saturation signal levels," Sony said.
Sony pioneered stacked sensors that put fast memory and other electronics directly under the sensor, allowing for faster readout speeds and thus rapid burst shooting and reduced rolling shutter (jello effect) on cameras and smartphones. This latest sensor uses a similar idea, but packs the pixel transistors onto a separate substrate underneath the photodiode layer.
