Sony has announced that it has "succeeded in developing the world’s first stacked CMOS image sensor technology with 2-Layer Transistor Pixel".

"Erm, what?" I hear you cry. Well, according to Sony, whereas conventional CMOS image sensors’ photodiodes and pixel transistors occupy the same substrate, this new technology separates photodiodes and pixel transistors onto different substrate layers. This allegedly has the potential to roughly double the saturation signal level compared to conventional CMOS sensors, resulting in enhanced dynamic range and reduced noise.
