Latest Patents
One of Og-Hyun Lee's latest patents is a method of forming a non-volatile memory device. This device comprises an active region disposed in a predetermined region of a semiconductor substrate, a selection gate electrode crossing over the active region, and a floating gate electrode disposed on the active region parallel to the selection gate electrode. The design includes a tunnel insulating layer intervening between the active region and each of the selection gate electrode and the floating gate electrode, along with a separation insulating pattern. Additionally, an erasing gate electrode is positioned over the floating gate electrode, crossing over the active region parallel to the selection gate electrode. This innovative design allows for improved functionality and efficiency in memory devices.
Another notable patent by Og-Hyun Lee is related to a split gate memory device and its fabricating method. In this invention, gate insulating and polysilicon layers are sequentially formed on a substrate. The polysilicon layer is then patterned, and a capping insulating layer is formed on portions of it. A pair of self-aligned control gates with identical bottom widths are created, with a tunnel insulating layer interposed between the control gates and the sidewalls of the polysilicon layer pattern. This method enhances the performance and reliability of memory devices.
