Latest Patents
Choi's latest patents include a groundbreaking invention titled "2-dimensional line-defects controlled silicon ingot, wafer and epitaxial wafer, and manufacturing process and apparatus therefor." This invention addresses a previously unreported defect in silicon ingots. It discloses a defect-controlled silicon ingot and wafer, along with a process and apparatus for their manufacturing. The innovation focuses on a crystal defect generated by a screw dislocation caused by the Horizontal Magnetic Czochralski (HMCZ) method. This defect develops into a jogged screw dislocation, which can propagate into a cross slip during the thermal process of cooling a crystal. Choi's invention modifies the upper heat shield structure 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.
