• abstract: As the demands for CMOS Image Sensors in the applications such as medical imaging, security systems, and Advanced Driver Assistance Systems (ADAS) are increasing, high sensitivity in the near-infrared (NIR) wavelength is more important. In addition, pixel pitch is also being miniaturized for high-resolution NIR sensors and single-chip integration. In this paper, we study the in-pixel Scattering Trench (IST) as the scattering structure for enhancing NIR sensitivity in the sub-micron pixel. By comparison between conventional and suggested pixels with IST, it was confirmed that the NIR sensitivity improved by up to 154.7% at wavelengths of 850nm in the 1.0$\mu$m pixel.
