Title: Seung Joo Nah: Innovator in Image Sensor Technology
Introduction
Seung Joo Nah is a prominent inventor based in Gwangju, South Korea. He has made significant contributions to the field of image sensor technology, holding a total of 4 patents. His work has been instrumental in advancing the capabilities of image sensors used in various applications.
Latest Patents
One of his latest patents involves an innovative image sensor design. This image sensor includes a substrate with opposite first and second surfaces, featuring first and second gates on the first surface. These gates extend in a first direction, while a first isolation layer is positioned between them, having a specific width in a second direction that crosses the first direction. Additionally, a second isolation layer is placed on the first isolation layer, with a smaller width than the first layer. Notably, the second isolation layer is closer to the second surface of the substrate than the first isolation layer. The vertical distance between these two layers is defined as being one-third or less of the height of the first isolation layer.
Another patent focuses on the pixel structure of an image sensor. This pixel includes a well located below a gate, containing a dopant at a first concentration. It also features a shallow trench isolation (STI) designed to electrically isolate the well. A channel stop is adjacent to at least one border between the well and the STI, containing a dopant at a second concentration that is higher than the first concentration.
