    摘要: A plasma etching apparatus includes an etching chamber and at least one processor. The etching chamber is configured to support a target therein. The at least one processor is configured to: determine a process condition for plasma etching the target before execution of a plasma etching process; and control an aspect of the chamber according to the process condition. The process condition includes a unit etching time over which the plasma etching process is to be continuously performed.

    摘要: Semiconductor devices are provided. The semiconductor devices may include an active pattern on a substrate. The active pattern may include a first source/drain region and a second source/drain region. The semiconductor devices may also include a bit line electrically connected to the first source/drain region, a first connection electrode electrically connected to the second source/drain region, and a capacitor on the first connection electrode. The capacitor may include a first electrode, a second electrode, and a dielectric pattern between the first and second electrodes. A lower portion of the dielectric pattern may overlap a top surface of the first connection electrode, and the first electrode may extend on an upper portion of a sidewall of the first connection electrode.

    摘要: A semiconductor device may include first pillar insulation patterns on a substrate, second pillar insulation patterns on the substrate, silicon patterns stacked on the substrate to be spaced apart from each other in a vertical direction, a word line on each of upper and lower surfaces of each silicon pattern, a bit line contacting a first sidewall of at least a first silicon pattern of the silicon patterns, and a capacitor contacting a second sidewall of the first silicon pattern. Each of the first pillar insulation patterns may extend in the vertical direction from an upper surface of the substrate. The first pillar insulation patterns may be spaced apart from each other in a first direction, and may be aligned in a line. Each of the second pillar insulation patterns may extend in the vertical direction. The second pillar insulation patterns may be spaced apart from each other in the first direction, and may be aligned in a line. The second pillar insulation patterns and the first pillar insulation patterns may overlap with each other in a second direction perpendicular to the first direction. Each of the silicon patterns may extend in the second direction and be positioned between two first pillar insulation patterns and between two second pillar insulation patterns, and each of the silicon patterns may include two sidewalls opposite each other in the first direction and having a straight line shape. Each word line may extend in the first direction to cross the silicon patterns. Each word line may contact a sidewall of at least one insulation pattern of the first pillar insulation patterns and/or at least one insulation pattern of the second pillar insulation patterns. The bit line may extend in the vertical direction. The capacitor may be disposed in a horizontal direction to have a dielectric layer horizontally between a lower electrode and an upper electrode.
