Title: Innovations by Kyong-Min Kim
Introduction
Kyong-Min Kim is a notable inventor based in St. Charles, MO (US). She has made significant contributions to the field of semiconductor materials, holding a total of 8 patents. Her work focuses on enhancing the processes involved in crystal growth, which is crucial for the production of high-quality semiconductor materials.
Latest Patents
Among her latest patents is the "Heat shield assembly and method of growing vacancy rich single crystal." This invention involves a heat shield assembly used in a Czochralski crystal puller. It selectively shields a monocrystalline ingot of semiconductor material to control the type and number density of agglomerated defects in the crystal structure. The assembly consists of an upper heat shield connected to a lower heat shield, which can telescope into an intermediate heat shield. This design minimizes the profile of the heat shield assembly within the crystal growth chamber while allowing for precise control during the formation of the monocrystalline ingot.
Another significant patent is the "Non-dash neck method for single crystal silicon growth." This method prepares a single crystal silicon rod using the Czochralski method. It is characterized by allowing a large diameter, dislocation-free seed crystal to thermally equilibrate before initiating growth. This process helps avoid dislocations caused by thermal shock. Additionally, a resistance heater is employed to melt the lower tip of the seed crystal, forming a molten cap before contact with the melt. The result is a dislocation-free silicon rod capable of supporting significant weight during growth and handling.
