Latest Patents

One of Ki-Jun Yun's latest patents is titled "Vertical semiconductor device and fabrication method thereof." This patent describes a method for fabricating a semiconductor device that involves forming an alternating stack consisting of a lower multi-layered stack and an upper multi-layered stack. The process includes alternately stacking a dielectric layer and a sacrificial layer over a substrate. Additionally, it details the formation of a vertical trench that divides the upper multi-layered stack into dummy stacks. An asymmetric stepped trench is also formed, extending downward from the vertical trench to divide the lower multi-layered stack into a pad stack and a dummy pad stack. This innovative method includes the creation of a first stepped sidewall at the edge of the pad stack and a second stepped sidewall at the edge of the dummy pad stack, which occupies less area than the first.
