Recently, the domestic CMOS manufacturer OmniVision officially announced that it has realized the world's smallest 0.56μm pixel technology.
Howe said that the R&D team has verified that even if the size of a single pixel is already smaller than the wavelength of red light, reducing the size of the pixel is not limited by the wavelength of incident light.
According to the information released by Howe, the design of its 0.56μm pixel is implemented using the 28nm process dedicated to TSMC's CMOS image sensor, while the logic layer uses the 22nm process node.
The pixels use deep photodiodes and OmniVision PureCelPlus technology, enabling them to achieve QPD and QE performance comparable to their own 0.61μm pixels.
In addition, OmniVision also announced that its first 200MP image sensor with 0.56μm pixels will be released in the second quarter of 2022, and samples are planned to be launched in the third quarter.
Well-known blogger @Digital Chat Station revealed: "There are still a lot of sensors with 200 million pixels. In addition to the 1/1.22" 0.64μm Samsung HP1, OmniVision also has two node versions of 0.61μm and 0.56μm, 1/1.28"1/ 1.4"± oversized sole, the rear one is positioned lower. The mid-to-high-end models with partial image positioning can be considered, it sounds like a good gimmick.”
This means that the mid-range model is expected to use the OmniVision sensor to achieve a 200 million pixel main camera, which can greatly improve the resolution, and more importantly, through the all-in-one algorithm, to achieve a larger single pixel area on the side, It is worth looking forward to improving the low-light shooting ability and picture effect.
