The agitator includes a rotary shaft rotatably installed in a reactor, rotor blades installed at an outer circumference of the rotary shaft and rotated with the rotary shaft to agitate a material therein, and an agitating hook constituted by a pair of members spaced apart from each other at an inner wall of the reactor and through which the rotor blades pass. Here, a gap between the agitating hook is larger at an outlet port through which the rotor blade leaves than at an inlet port through which the rotor blade enters. Since a pressure is uniformly applied from the inlet port through which the rotor blade enters to the outlet port through which the rotor blade leaves, a torsional moment applied to the agitating hook is minimized. Therefore, it is possible to improve durability of the agitating hook and increase reliability of products. | 12-27-2012 |

20150348795 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - In a method of manufacturing a semiconductor device, which uses a triple patterning process, a porous layer covering sidewalls and an upper surface of a polymer-containing pattern is formed on a layer to be etched. A decomposition gas is supplied to the polymer-containing pattern through the porous layer, and a portion of the polymer-containing pattern is decomposed to form a reduced polymer-containing pattern and form a void between the reduced polymer-containing pattern and the porous layer. A portion of the porous layer is removed to form a porous spacer pattern spaced apart from the reduced polymer-containing pattern. The layer to be etched is etched by using the reduced polymer-containing pattern and the porous spacer pattern as an etch mask. | 12-03-2015 |
