Title: Innovations of Sung Tae Lee in Three-Dimensional Memory Devices
Introduction
Sung Tae Lee is a prominent inventor based in Yokkaichi, Japan, known for his significant contributions to the field of memory devices. With a total of six patents to his name, he has made remarkable advancements in technology that enhance data storage capabilities.
Latest Patents
One of his latest patents is titled "Three-dimensional memory device including stairless word line contact structures for and method of making the same." This invention involves the formation of an alternating stack of insulating layers and sacrificial material layers over a substrate. Memory openings and support openings are created through this stack, leading to the development of memory opening fill structures and support pillar structures. The innovation includes the formation of via cavities that extend to each of the sacrificial material layers without creating any stepped surfaces. These cavities can be positioned in areas that do not overlap with support pillar structures or in areas that include at least one support pillar structure. The process also involves forming sacrificial via fill structures in the via cavities, which are later replaced with electrically conductive layers. The removal of these sacrificial structures allows for the creation of a combination of a tubular dielectric spacer and a contact via structure within the cavities.
