Latest Patents

One of Sang-Do Lee's latest patents is focused on a semiconductor device and the method for fabricating the same. This innovative method includes several steps: forming a mold stack pattern with multiple openings in the upper portion of a substrate, which consists of a mold layer and a supporter layer that are stacked. The process continues with the formation of a bottom electrode layer that fills the openings and covers the supporter layer. Additionally, a filler portion is disposed inside the openings, along with a barrier portion that extends upwardly from the filler portion. An electrode cutting portion is created by selectively etching the bottom electrode layer to expose the surface of the supporter layer. The method also involves forming a supporter by using the barrier portion as an etch barrier and etching the supporter layer exposed by the electrode cutting portion. Finally, the barrier portion is selectively removed to create a hybrid pillar-type bottom electrode within the openings, followed by the removal of the mold layer.
