Latest Patents
One of Ju-Wan Kim's latest patents focuses on vertical memory devices and methods of manufacturing the same. This innovative method involves the alternate formation of insulation layers and sacrificial layers on a substrate. A hole is created through these layers to expose the substrate's top surface, followed by the enlargement of the hole's interior portion. A semiconductor pattern is then formed to partially fill this enlarged hole. The process continues with the formation of a blocking layer, a charge storage layer, and a tunnel insulation layer on the sidewall of the hole and the semiconductor pattern. The final steps include the removal of certain layers to expose the semiconductor pattern's top surface and the formation of a channel on it.
Another significant patent by Kim pertains to an isolation layer structure and the methods for forming it, which includes first to fourth oxide layer patterns. This structure is designed to enhance the performance of semiconductor devices by defining trenches with varying widths and ensuring the integrity of the oxide layer patterns.
