Latest Patents

One of Taeseop Choi's latest patents is a method of manufacturing semiconductor devices. This innovative method involves stacking an etching target layer, a first mask layer, an under layer, and a photoresist layer on a substrate. The process includes irradiating extreme ultraviolet (EUV) radiation on the photoresist layer to form a photoresist pattern. Additionally, a nitrogen plasma treatment is performed on the photoresist pattern while using the first mask layer as an etching stop layer. This treatment continues until the top surface of the first mask layer is exposed, allowing for the under layer to be etched and form an under pattern below the photoresist pattern.

Another notable patent relates to semiconductor devices themselves. This invention includes a substrate with an active region extending in a first direction, along with a plurality of bit lines running across the active region in a second direction. The design features a first spacer on the sidewall of the bit line and a storage node contact on the active region between adjacent bit lines. The intricate design of the first spacer includes multiple parts with varying vertical thicknesses, enhancing the functionality and efficiency of the semiconductor device.
