Title: Hyoung-jo Jeon: Innovator in Surface Inspection and Semiconductor Technology

Introduction

Hyoung-jo Jeon is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the fields of surface inspection and semiconductor device manufacturing. With a total of 6 patents to his name, Jeon continues to push the boundaries of technology through his innovative methods.

Latest Patents

One of Jeon's latest patents is a surface inspecting method. This method involves irradiating an incident light beam of a first polarized state on a target object. The incident light beam comprises parallel light and has a specific cross-sectional area. The method measures a second polarized state of a reflected light beam from the target object and performs inspection on the entire area of the target object based on the variation between the first and second polarized states.

Another notable patent is a method for detecting overlay errors and manufacturing semiconductor devices using the same. This method includes forming a first overlay key with spaced apart target patterns on a first layer of a substrate. It also involves forming a second overlay key on a second layer of the substrate below the first layer. The method uses incident light to obtain a phase pattern of light reflected from both layers, allowing for the detection of overlay errors based on the calculated positions of peak or valley points in the phase pattern.
