Abstract: A semiconductor device may include a substrate including center and edge regions, active patterns on the substrate, channel patterns on the active patterns, source/drain patterns connected to the channel patterns, and gate electrodes on the channel patterns. Each of the source/drain patterns may include a buffer layer in contact with a corresponding one of the channel patterns and a main layer on the buffer layer. The main layer of each of the source/drain patterns may include first and second semiconductor layers, which may be sequentially stacked and contain germanium. A concentration of the germanium in the first semiconductor layer may be higher on the center region than on the edge region, and a concentration of the germanium in the second semiconductor layer may be lower on the center region than on the edge region.

Abstract: This clothes care apparatus comprises: a main body having a care room; a blower configured to guide an airflow while provided in the main body; an inner door coupleable to the main body; and an outer door coupleable to the inner door, which forms, together with an inner door, accommodating space to accommodate clothes. The outer door including a clothes support member arranged to support clothes in the accommodating space, wherein the outer door is arranged to be rotatable with respect to the inner door so as to open and close the accommodating space. The inner door comprises a partition to separate the care room and the accommodating space and having an outlet hole to allow the airflow guided by the blower to be discharged toward clothes that are supported by the clothes support member.
