Sony has announced that its internal semiconductor division has developed the world's first stacked CMOS image sensor.
Sony's NEW breakthrough sensor that captures TWICE the light
According to Sony Semiconductor Solution Corporation, this technology has great potential to further improve high-quality digital imaging. This new sensor doubles the amount of light collected compared to current chips.
CMOS stands for Complementary Metal-Oxide Semiconductor and, when used as part of an image sensor, functions as the film for a digital camera. The sensor consists of many photodiodes and pixel transistors that convert a subject into a digital image.
Normally, these photodiodes and transistors occupy the same space. What is special about Sony’s sensor is that it separates the two and places the transistors underneath the photodiodes. This new form factor allows Sony to optimize each layer to increase the amount of light that can be captured and extend the range of a camera. It also reduces noise in an image to ensure higher quality.
