Latest Patents
Hwa-Jin Jo holds 2 patents related to his groundbreaking work. His latest patents include a method for creating 2-dimensional line-defects controlled silicon ingots, wafers, and epitaxial wafers. This invention addresses a previously unreported defect and introduces a process and apparatus for manufacturing defect-controlled silicon products. The new defect arises from a crystal defect generated during the Horizontal Magnetic Czochralski (HMCZ) method, where a strong horizontal magnetic field causes a screw dislocation to develop into a jogged screw dislocation. This defect can propagate into a cross slip during the thermal cooling process of the crystal. Jo's invention modifies the upper heat shield structure between the heater and the silicon melt, controlling the initial and operational conditions of the silicon single crystalline ingot growth process. This innovation aims to reduce screw dislocations caused by the strong magnetic field and prevent their propagation into cross slips.
