Title: Innovations of Jin Man Ha in Particle Contamination Prevention

Introduction

Jin Man Ha is a notable inventor based in Yuseong-gu, South Korea. He has made significant contributions to the field of substrate processing, particularly in methods aimed at reducing particle contamination. With a total of 2 patents, his work has garnered attention in the industry.

Latest Patents

One of Jin Man Ha's latest patents focuses on a method for preventing particle contamination within a processing chamber. This innovative approach involves preheating the substrate within the chamber to create a thermophoresis effect. This effect helps ensure that particles that are not adhered to a surface do not settle on the substrate. One method he proposes for increasing the substrate temperature is plasma loading, which involves providing an inert gas plasma to heat the substrate. Another method is high pressure loading, where the substrate is heated while the chamber pressure is increased to between about 1 Torr and about 10 Torr. By rapidly increasing the substrate temperature prior to processing, the likelihood of particle contamination is significantly reduced.
