Title: Hyoun-min Baek: Innovator in Image Sensor Technology

Introduction

Hyoun-min Baek is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of image sensor technology, holding 2 patents that showcase his innovative approach to enhancing image capture and processing.

Latest Patents

Baek's latest patents include a method for manufacturing an image sensor and a method for operating the same. The first patent describes an image sensor that features a photoelectric conversion section within a semiconductor substrate. This sensor includes a capping layer of a first conductivity type and a photodiode of a second conductivity type positioned below the capping layer. The photodiode's upper surface is deeper than approximately 1 μm from the upper surface of the semiconductor substrate. The design incorporates a charge detection section that receives charges stored in the photoelectric conversion through a charge transfer section, converting these charges into electrical signals. Additionally, a voltage application section is included to control the width of the depletion layer on the photodiode, while a signal operation section generates red, green, and blue signals based on the charge detection section's output.

His second patent focuses on a complementary metal oxide semiconductor (CMOS) image sensor and the method of forming it. This CMOS image sensor consists of a semiconductor substrate that contains both a photodiode region and a transistor region. An optical path is established between a micro lens situated on the photodiode region and a photodiode formed on the substrate. This optical path features an inner lens located between an intermetal insulation layer on the photodiode region and a transparent optical region above the inner lens, which typically has a different refractive index than the inner lens.
