    Abstract: A memory device includes a first stack structure, a second stack structure, a channel pillar, a storage layer, and a conductive pillar. The first stack structure includes a first insulating layer and a first conductive layer located on the first insulating layer. The second stack structure is located on the first stack structure and includes a plurality of second conductive layers and a plurality of second insulating layers which alternate with each other. The channel pillar penetrates through the second stack structure and extends to the first stack structure. The storage layer is located between the channel pillar and the first stack structure and between the channel pillar and the second stack structure. The conductive pillar is located in the first conductive layer and electrically connected to the first conductive layer and the substrate.

    Abstract: Provided is a method of fabricating a semiconductor device, including the following. A first material layer, a second material layer and a mask layer are formed on a substrate. A portion of the second material layer is removed by performing a first etching process with the mask layer as a mask, so as to expose the first material layer and form a first pattern layer and a second pattern layer. A portion of the first material layer is removed by performing a second etching process with the mask layer as a mask, so as to expose a portion of the substrate. A portion of the substrate is removed by performing a third etching process with the mask layer as a mask, so as to form first trenches and second trenches. Sidewalls of the second trenches and a surface of the substrate form at least two different angles.

    Abstract: A cluster tool is disclosed that can increase throughput of a wafer fabrication process by facilitating removal of barrier overhang in contact holes of contact film stacks. Individual chambers of the cluster tool provide for deposition of barrier material onto a semiconductor structure, depositing over with an amorphous carbon film (ACF), etching back the ACF, and etching a corner region of the contact hole. Removal of the barrier overhang improves the quality of metal fill-in of the contact hole. An expectedly ensuing feature entails a technique in which filling-in of the contact hole with a metal such as tungsten can be achieved with attenuated or eliminated adverse consequence.

    Abstract: A three-dimensional stacked IC device includes a stack of at least first, second, third and fourth contact levels at an interconnect region. Each contact level has a conductive layer and an insulation layer. First, second, third and fourth electrical conductors pass through portions of the stack of contact levels. The first, second, third and fourth electrical conductors are in electrical contact with the first, second, third and fourth conductive layers, respectively. A dielectric sidewall spacer circumferentially surrounds the second, third and fourth electrical conductors so that the second, third and fourth electrical conductors only electrically contact the respective second, third and fourth conductive layers.
