Latest Patents

Ji Hyeog Kim holds a patent for a "Method for fabricating flash memory cell." This method involves forming first gate insulating films and polysilicon layers in succession on a substrate. The first gate insulating films and polysilicon layers extend in a first direction, and buried regions are formed in the substrate under portions of the polysilicon layers. The process includes forming second insulating films, control gates, and cap insulating films in succession on the substrate and polysilicon layers. Additionally, first sidewall spacers are created at both sides of the control gates. The method further includes forming floating gates by patterning the polysilicon layers using the first sidewall spacers as masks, forming field insulating films between the floating gates, and forming erasure gates on the field insulating films between the floating gates. Ji Hyeog Kim has 1 patent to his name.
