Abstract
A semiconductor device includes a stack formed on a substrate and memory strings penetrating the stack along a first direction. The stack includes conductive layers and insulating layers that alternately stacked. Each of the memory strings includes a channel layer, a memory structure, a first conductive pillar and a second conductive pillar. The channel layer, the first conductive pillar and the second conductive pillar extend along a first direction. The memory structure is disposed between the stack and the channel layer. The first conductive pillar and the second conductive pillar are electrically isolated from each other, and are respectively coupled to a first portion and a second portion of the channel layer. The first portion is opposite to the second portion. The first portion is surrounded by the memory structure, and the second portion is exposed from the memory structure.
