    摘要: A semiconductor memory device may include: a stacking structure including a plurality of insulating layers and a plurality of gate electrodes alternately stacked on a substrate; a lower semiconductor pattern that protrudes from the top of the substrate; a vertical insulating pattern that extends in a vertical direction from the substrate and penetrates the stacking structure; and a vertical channel pattern on the inner surface of the vertical insulating pattern and contacting the lower semiconductor pattern, wherein an upper part of the lower semiconductor pattern includes a recess region including a curve-shaped profile, and in the recess region, the outer surface of a lower part of the vertical channel pattern contacts the lower semiconductor pattern along a curve of the recess region.

    摘要: A vertical memory device may include a channel connecting pattern on a substrate, gate electrodes spaced apart from each other in a first direction on the channel connecting pattern, and a channel extending in the first direction through the gate electrodes and the channel connecting pattern. Each of the electrodes may extend in a second direction substantially parallel to an upper surface of the substrate, and the first direction may be substantially perpendicular to the upper surface of the substrate. An end portion of the channel connecting pattern in a third direction substantially parallel to the upper surface of the substrate and substantially perpendicular to the second direction may have an upper surface higher than an upper surface of other portions of the channel connecting pattern except for a portion thereof adjacent the channel.

    摘要: A wafer processing apparatus may include a reaction tube extending in a vertical direction and defining a process chamber for receiving a boat that holds a plurality of wafers. A gas injector may be configured to supply a reaction gas into the process chamber and may include a gas distributor extending in the vertical direction in the reaction tube. The gas injector may have a plurality of ejection holes for spraying the reaction gas. An inner diameter of the gas distributor may be at least 10 mm, and a sectional area ratio of the total sectional area of the ejection holes to a sectional area of the gas distributor is about 0.3 or less.
