Sony is On the Way to Improve SmartPhone Cameras By Stacked Image Sensor Technology

Sony is the most renowned camera sensor maker for smartphones. Businesses choose the Japanese technology giant in favor of other companies due to its innovativeness and ability to satisfy the demands of customers. To stay on top, Sony is known for creating new innovations each and every so often. According to an official press announcement (via Android Authority) from the company, it has recently revealed its latest breakthrough in the field of stacked image sensors during the IEEE International Electron Devices Meeting that began on the 11th of December 2021.

Sony claims that it has created the first CMOS Image Sensor technology that has two-layer transistor pixels. In simpler terms Sony has enhanced the existing technology for stacked sensors by making a few changes to improve performance.

The firm states that pixel transistors and photodiodes of traditional CMOS image sensors are both on an identical pixel sublayer. Sony is modified this arrangement by creating distinct pixel substrate layers to accommodate photodiodes and pixel transistors , respectively.

This Japanese company claims its new sensor technology can double the its saturation level, and, in turnincreases the range of dynamic. Furthermore, as the transistor size of amps can be increased using this technology, noise during dark conditions is also reduced.

Then, Sony states that its stacked CMOS image sensor technology that incorporates 2-layer transistor pixels enhances the quality of pixels at their present size and also smaller. This implies that the company could eventually release the 100-megapixel sensors similar to Samsung in order to benefit from this technology.

The conventional CMOS image sensors reside on the same pixels substrate layer. Sony offers modified this arrangement by using distinct pixels substrate layers for photodiodes and pixel transistors , respectively.
