Title: Innovations of Inventor Yun Chung
Introduction
Yun Chung is a notable inventor based in Santa Clara County, California. He has made significant contributions to the field of imaging technology, holding a total of three patents. His work focuses on enhancing the performance and resolution of imaging sensors, particularly in electron bombarded devices.
Latest Patents
Yun Chung's latest patents include innovative methods for backside imaging through a doped layer. This technique involves backthinning in an area-selective manner applied to CMOS imaging sensors for use in electron bombarded active pixel array devices. A further arrangement results in an array of collimators aligned with pixels or groups of pixels, providing improved image contrast for such image sensors. The provision of a thin P-doped layer on the illuminated rear surface serves as both a diffusion barrier, resulting in improved resolution, and a functional shield for reference pixels. Additionally, a gradient in the concentration of the P-doped layer optimizes electron collection at the pixel array.
Another significant patent by Yun Chung is related to backside thinning of image array devices. Similar to his previous work, this patent also applies backthinning in an area-selective manner to imaging sensors for use in electron bombarded devices. The arrangement of collimators aligned with pixels enhances image contrast, while the thin P-doped layer on the rear surface provides a diffusion barrier and a functional shield for reference pixels. The gradient in concentration of the P-doped layer further optimizes electron collection at the pixel array.
