CMOS Image Sensor Layers at a Glance
The onsemi CMOS Image Sensor Wafer consists of the following layers:
• Microlens Array—Small lenses that collect and focus light onto light-sensitive areas of the sensor.
• Color Filter Array (CFA)—Mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information.
• Photodiode—Semiconductor that converts light into an electrical current.
• Pixel Transistors—Transistors provide gain or bugger [sic, typo "buffer"?] of electrical charge from the photodiode.
• Bond Layer—Connects the Active Pixel Array to the ASIC layer
• ASIC—Logic layer for features such as error correction, memory for multi-exposures, cores for cybersecurity, hardware blocks for functional safety, and high-speed I/O.
tinyML Summit 2023: Deploying Visual AI Solutions in the Retail Industry
Mark HANSON , VP of Technology and Business Innovation, Sony Semiconductor Solutions of America
An image sensor with AI-processing capability is a novel architecture that is pushing vision AI closer to the edge to enable applications at scale. Today many AI applications stall in the PoC stage and never reach commercial deployment to solve real-world problems because existing systems lack simplicity, flexibility, affordability, and commercial-grade reliability. We’ll investigate why the retail industry struggles to keep track of stock on its retail shelves while relying on retail employees to manually monitor stock and how our (AITRIOS) vision AI application for on-shelf-availability can eliminate complexity and inefficiency at scale.

"bugger of electrical charge from the photodiode"? Will have to learn more about this technique...
