Title: Kwang Su Choe: Innovator in Silicon Technology

Introduction

Kwang Su Choe is a prominent inventor based in Sungnam-shi, South Korea. He has made significant contributions to the field of silicon technology, holding a total of 5 patents. His work focuses on innovative methods for fabricating silicon-on-insulators (SOIs), which are crucial for modern electronic devices.

Latest Patents

Choe's latest patents include groundbreaking methods for creating thin buried oxides through low-dose oxygen implantation into modified silicon. This method allows for the fabrication of SOI structures with a thin, uniform buried oxide region beneath a silicon-containing over-layer. The process involves modifying the surface of a silicon substrate to contain a high concentration of vacancies, followed by the implantation of oxygen ions and subsequent annealing to form the buried oxide region.

Another notable patent involves the oxidation of graded porous silicon to fabricate SOI substrate structures. This method begins with the implantation of a dopant into a silicon substrate, followed by activation and anodization in a hydrofluoric acid solution. The resulting graded porous silicon undergoes oxidation, converting the fine buried porous layer into a buried oxide while the coarse top layer solidifies into a silicon-containing over-layer.
