Abstract:
A capacitor dielectric can be between the storage node and the electrode layer. A supporting pattern can be connected to the storage node, where the supporting pattern can include at least one first pattern and at least one second pattern layered on one another, where the first pattern can include a material having an etch selectivity with respect to the second pattern.
Abstract:
A semiconductor memory device can include a first conductive line crossing over a field isolation region and crossing over an active region of the device, where the first conductive line can include a first conductive pattern being doped, a second conductive pattern, and a metal-silicon-nitride pattern between the first and second conductive patterns and can be configured to provide a contact at a lower boundary of the metal-silicon-nitride pattern with the first conductive pattern and configured to provide a diffusion barrier at an upper boundary of the metal-silicon-nitride pattern with the second conductive pattern.
Abstract:
An integrated circuit device with capacitors and methods of forming the integrated circuit device are provided. The methods may include forming a first lower capacitor electrode pattern on an inner surface of a hole in a mold layer. The first lower capacitor electrode pattern may have a hollow cylindrical shape and an opening in an upper surface. The method may further include forming a second lower capacitor electrode pattern plugging the opening and an upper surface of the second lower capacitor electrode pattern may be planar. The first and the second lower capacitor electrode patterns may comprise a lower capacitor electrode including a void. Additionally, the method may include removing the mold layer to expose the lower capacitor electrode, forming a dielectric layer on the lower capacitor electrode, and forming an upper capacitor electrode layer on the dielectric layer.

Abstract:
A semiconductor device with vertical channel transistors and a method of fabricating the same are provided. A method of fabricating the semiconductor device includes patterning a substrate to form a trench that defines an active region, forming a sacrificial pattern in a lower region of the trench, forming a spacer on an upper sidewall of the trench, recessing a top surface of the sacrificial pattern to form a window exposing a sidewall of the active region between the spacer and the sacrificial pattern, doping a sidewall of the trench through the window to form a doped region in the active region, and forming a wiring in the trench to be connected to the doped region.
