Title: Jong Doo Lee and Substrate-Treatment Innovations.

Introduction

Jong Doo Lee is an inventor based in Cheonan-si, South Korea. His work includes inventions for substrate-treatment equipment, and he is associated with SEMES Co., Ltd. Lee is credited with 3 patents.

Latest Patents

Lee’s recent patent work includes two substrate-treatment apparatus inventions.

“Substrate Treating Apparatus” describes a housing made of two bodies that form a treatment space for processing a substrate. An actuator moves the second body vertically to open or seal that space. A stretchable pipe connected to the moving body expands or contracts as it moves, allowing fluid to flow.

“Apparatus for Treating Substrate” describes a system that supplies treating fluid to a space within a body and exhausts it afterward. The body has two relatively movable parts, with an anti-friction member configured to cover continuously at least two surfaces of those parts to help prevent friction.

Career Highlights

Lee’s listed inventions focus on mechanical features of substrate-processing equipment, including movable housing components, fluid handling, and friction reduction. These designs address aspects of operating and maintaining treatment spaces in semiconductor or other substrate-processing systems.

Collaborations

Lee’s listed coworkers include Sang Min Lee and Jin Mo Jae. His work is associated with SEMES Co., Ltd., a company involved in semiconductor manufacturing equipment.
