Latest Patents

One of Ji-Woon Im's latest patents is titled "Methods of manufacturing a vertical memory device." This patent describes a method where a first sacrificial layer, including a nitride, is formed on a substrate. A mold is created with an insulation layer and a second sacrificial layer that are alternately and repeatedly stacked on the first sacrificial layer. The insulation layer and the second sacrificial layer consist of a first oxide and a second oxide, respectively. A channel is formed through the mold and the first sacrificial layer, and an opening is created to expose the upper surface of the substrate. The first sacrificial layer is then removed through this opening to form a first gap, followed by the formation of a channel connecting pattern to fill the gap. The second sacrificial layer is ultimately replaced with a gate electrode.

Another notable patent is for a "Nonvolatile memory device and a method for fabricating the same." This invention includes a substrate with a cell array region and a connection region. An electrode structure is formed on both regions, consisting of multiple laminated electrodes. The design features a first recess in the electrode structure on the connection region, positioned between the cell array region and a second recess. Additionally, a plurality of vertical wirings is formed on the exposed electrodes by the first recess.
