Custom stacked CMOS sensors will add new performance and features in a tiny package
In December 2021, Sony Semiconductor Solutions announced a breakthrough at the IEEE International Electron Devices Meeting with a new stacked CMOS image sensor technology. Where conventional CMOS image sensors place photodiodes and pixel transistors on the same plane, this new technology separated photodiodes and pixel transistors onto different substrate layers. This new approach promised wider dynamic range and reduced noise.
