At Photonics West in San Francisco, California (US), imec, a research and innovation hub in nano-electronics and digital technologies, is introducing a new image sensor with integrated color (Red Green Blue, RGB) and narrow-band near-infrared (NIR) filters. This breakthrough optical filter integration platform will enable many different application fields from medical, industrial, security surveillance, automotive to virtual and augmented reality, where near-infrared signals need to be extracted and overlaid on top of color images.
Imec’s RGB-NIR multispectral platform demonstrates for the very first time the possibility to integrate together standard RGB color filters, NIR-cut filter, NIR narrow band-pass filters and on-chip microlenses technology, down to small pixels as small as 5µm today. The NIR band-pass filter and design pattern implementation can be tuned to match requirements of a specific application case, e.g. the wavelength of a particular laser or LED light.
Leveraging imec’s background in CMOS scaling, its semiconductor fab, equipment and process technology, imec designs and manufactures interference based optical filters at wafer level, deposited and patterned directly on top of the CMOS image sensor pixels. Imec’s unique infrastructure provides very integrated, clean (class 1 – particle free) and high yield optical filter integration with strong potential for scalability in high-volume.
The first image sensor and camera prototypes will be demonstrated at SPIE Photonics West in San-Francisco on booth 4333 (North Hall of Moscone center). They are already available for early sampling and evaluation by strategic partners.
