Latest Patents
One of Ji-Yeong Hwang's latest patents involves a method of manufacturing vertical semiconductor devices. In this innovative process, an insulation layer and a sacrificial layer are alternatively and repeatedly formed on a substrate to define a structure. The structure is then etched to create a hole that exposes the substrate. A first semiconductor pattern is formed in the lower portion of the hole, while a blocking pattern, a charge storage pattern, a tunnel insulation pattern, and a first channel pattern are created on the sidewall of the hole. A second channel pattern is formed on the first channel pattern and the semiconductor pattern, followed by the formation of a second semiconductor pattern on a portion of the second channel pattern. This defines an upper channel pattern that includes both the second channel pattern and the second semiconductor pattern. Finally, the sacrificial layers are replaced with a plurality of gates, each made from a conductive material.
