Title: Dong-Pyo Hong: Semiconductor Wafer Grinding and Cleaning Innovation

Introduction

Dong-Pyo Hong is an inventor associated with Yongin, South Korea, and Samsung Electronics Co., Ltd. His patent work addresses semiconductor wafer processing, with a focus on grinding and removing dust from wafer surfaces. The available information lists 1 patent for Hong.

Latest Patents

Hong’s listed patent, “Apparatus for Grinding a Semiconductor Wafer While Removing Dust,” describes equipment that polishes a wafer and removes contaminants during and after grinding. A grinding device holds the wafer on a chuck table, polishes it with a grinding wheel, and supplies water to the contact area. A separate cleaning device rotates the polished wafer and applies detergent to its surfaces to remove remaining dust. A controller coordinates the grinding and cleaning devices. The design aims to prevent dust from being drawn onto the wafer’s front side and to improve contaminant removal throughout processing.

Career Highlights

Hong’s listed invention concerns a practical challenge in semiconductor manufacturing: keeping wafer surfaces clean during precision grinding. By combining water-assisted grinding with a subsequent detergent-cleaning stage, the apparatus integrates polishing and dust removal into a coordinated process.
