IMAGE BESTGe-on-Si Image Sensor with NIR SensitivityAMMJENACIONAL

In a recent preprint (https://arxiv.org/ftp/arxiv/papers/2209/2209.14242.pdf) Ponizovskaya-Devine et al. describe a new Ge-on-Si image sensor with enhanced sensitivity up to 1.7um for NIR applications.


Abstract

We present a Germanium “Ge-on-Si” CMOS image sensor with backside illumination for the near-infrared (NIR) electromagnetic waves (wavelength range 300–1700 nm) detection essential for optical sensor technology. The micro-holes help to enhance the optical efficiency and extend the range to the 1.7 µm wavelength. We demonstrate an optimization for the width and depth of the nano-holes for maximal absorption in the near infrared. We show a reduction in the cross-talk by employing thin SiO2 deep trench isolation in between the pixels. Finally, we show a 26–50% reduction in the device capacitance with the introduction of a hole. Such CMOS-compatible Ge-onSi sensors will enable high-density, ultra-fast and efficient NIR imaging.

IMAGE BESTSigma Foveon sensor will be ready in 2022AMMJENACIONAL

From PetaPixel : Sigma’s CEO Kazuto Yamaki has revealed that the company’s efforts in making a full-frame Foveon sensor are on track to be finished by the end of the year.  Sigma’s Foveon sensors use a proprietary three-layer structure in which red, green, and blue pixels each have their own full layer. In traditional sensors, the three pixels share a single layer in a mosaic arrangement and the camera “fills in” missing colors by examining neighboring pixels. Since each pixel of a photo is recorded in three colors, the resulting photo should be sharper with better color accuracy and fewer artifacts. The release had been delayed on at least two occasions in the past due to technical challenges, once in 2020 and again in 2021. The initial announcement about this sensor was made back in 2018. In February 2022, Yamaki indicated that the company was in stage 2 of testing, and the final third stage will involve mass-production testing.
