Backside-Patterned Nanostructured Lens in BSI CMOS Sensors

This invention introduces a novel approach to enhancing backside-illuminated (BSI) Complementary Metal-Oxide-Semiconductor (CMOS) sensors by integrating patterned nanostructured lens elements, such as metalenses, directly into the backside silicon layer or additional material layers. Unlike conventional microlens arrays, these nanostructured lenses...
