Introduction

Sang-hyun Kim is a notable inventor based in Hwaseong-si, South Korea. He has made significant contributions to the fields of ultrasound technology and semiconductor manufacturing. With a total of 8 patents, his work has had a considerable impact on medical imaging and device fabrication.

Latest Patents

One of his latest patents involves a method, apparatus, and system for generating ultrasound. This invention provides an apparatus and method to generate ultrasound that can be transmitted from an ultrasound irradiation device. The process includes acquiring a medical image that contains anatomical information about a subject and calculating the characteristics of the tissue that may affect the propagation of the ultrasound. The apparatus and method also determine parameters of the ultrasound to create a focal point on the subject using the calculated characteristics, ultimately generating the ultrasound according to the determined parameters.

Another significant patent focuses on methods of manufacturing photomasks, forming photoresist patterns, and manufacturing semiconductor devices. This method of patterning a photoresist layer involves forming a photoresist layer on a substrate and exposing it to light using a first light source to induce a chemical change. A post-exposure bake process is then performed, which includes irradiating the photoresist layer with at least two shots of laser light from a second light source, heating the layer to a specific temperature, followed by a developing process that selectively removes portions of the photoresist layer.
