Introduction

Seungpil Chung is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to device design and fabrication.

Latest Patents

One of his latest patents is for a three-dimensional semiconductor device. This device includes a substrate with a cell region and a connection region. A stack is disposed on the substrate, featuring a vertical channel structure that penetrates the stack in the cell region. The stack comprises electrode patterns and insulating patterns that are alternately and repeatedly stacked on the substrate. Each electrode pattern extends in a first direction and includes a pad portion positioned in the connection region. The pad portion has a first sidewall and a second sidewall that extend in the first direction on opposite sides. Notably, the first sidewall features a recessed portion that crosses the first direction toward the second sidewall.

Another significant patent involves semiconductor memory devices and methods for fabricating them. This patent describes a semiconductor memory device that includes a substrate with a cell region and a peripheral region. It features a gate stack with multiple insulating layers and gates alternately stacked on the cell region. A stress buffer layer is placed on the gate stack, and a vertical channel extends through the gate stack, electrically connected to the substrate. A memory layer wraps around the vertical channel, and a bit line may be provided on the gate stack. The method of fabrication includes forming the buffer stress layer directly on an upper insulating layer of a stack, which helps inhibit warping of the substrate during the device's fabrication.
