Latest Patents

One of Jong-Hyun Yoo's latest patents is a method for fabricating a vertical semiconductor device. This method involves forming an alternating stack that includes a lower multi-layered stack and an upper multi-layered stack by alternately stacking a dielectric layer and a sacrificial layer over a substrate. The process includes forming a vertical trench that divides the upper multi-layered stack into dummy stacks. Additionally, it features an asymmetric stepped trench that extends downward from the vertical trench to divide the lower multi-layered stack into a pad stack and a dummy pad stack. The formation of the asymmetric stepped trench includes creating a first stepped sidewall defined at the edge of the pad stack and a second stepped sidewall defined at the edge of the dummy pad stack, which occupies less area than the first stepped sidewall.
