Title: Eun-Sang Ji: Innovator in Silicon Technology
Introduction
Eun-Sang Ji is a prominent inventor based in Gumi-si, South Korea. He has made significant contributions to the field of silicon technology, particularly in the development of defect-controlled silicon ingots and wafers. His innovative work has led to the filing of multiple patents, showcasing his expertise and dedication to advancing technology.
Latest Patents
Eun-Sang Ji holds 2 patents, with his latest invention focusing on a 2-dimensional line-defects controlled silicon ingot, wafer, and epitaxial wafer, along with the manufacturing process and apparatus for these products. This invention addresses a previously unreported defect, introducing a defect-controlled silicon ingot and wafer. The new defect arises from a crystal defect generated when a screw dislocation, caused by the Horizontal Magnetic Czochralski (HMCZ) method, develops into a jogged screw dislocation. This defect propagates to form a cross slip during the thermal process of cooling a crystal. His invention modifies the shape and structure of the upper heat shield positioned between the heater and the ingot above the silicon melt. It also controls the initial and operational conditions of the silicon single crystalline ingot growth process to minimize screw dislocations caused by a strong horizontal magnetic field and prevent their propagation into cross slips.
