Imec Introduces New Snapshot Multispectral Image Sensor that Combines Color and Near-Infrared Imaging


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.

“An affordable, high resolution and high speed solution for integrating true RGB color combined with narrow-band NIR detection was essential to develop for future applications that need to detect or track near infra-red signals that should not be visible to human eyes” explains Andy Lambrechts, program manager for imec’s integrated imaging activities. “This capability to integrate a color view with one or several near-infrared narrow bands will be a key enabler for next-generation 3D, virtual reality (VR) & augmented reality (AR) imaging platforms. As well as in machine vision, medical, automotive and security surveillance applications.”

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.
