Abstract: A particulate matter collecting apparatus includes a duct, a water sprayer, a micro-channel forming unit, and an impactor. A gas-liquid mixed fluid is formed by spraying water to air flowing along the inside of the duct using the water sprayer. The gas-liquid mixed fluid collides with a collision plate of the impactor after passing through a plurality of micro-channels provided in the micro-channel forming unit. Particulate matter in air is collected by droplets or a liquid film formed on the plurality of micro-channels and the collision plate. Water flowing down from the plurality of micro-channels is discharged through a first water outlet.

Abstract: Disclosed is a method of fabricating a semiconductor device. The method includes forming a lower layer on a substrate, forming on the lower layer a sacrificial layer and an etching pattern, forming a first spacer layer on the sacrificial layer and the etching pattern, etching the sacrificial layer and the first spacer layer to form a sacrificial pattern and a first spacer on at least a portion of a top surface of the sacrificial pattern, forming a second spacer layer on the sacrificial pattern and the first spacer, etching the second spacer layer and the first spacer to form a second spacer on a sidewall of the sacrificial pattern, and partially etching the lower layer to form a pattern. The second spacer is used as an etching mask to partially etch the lower layer.

Abstract: In a method of cutting a fine pattern, a line structure is formed on a substrate. The line structure extends in a first direction, and includes a pattern and a first mask. The pattern and the first mask include different materials. A sacrificial layer is formed on the substrate to cover the line structure. The sacrificial layer is partially etched to form a first opening partially overlapping the line structure in a vertical direction. A portion of the first mask, an upper portion of the pattern and/or a portion of the sacrificial layer under the first opening are partially etched using an etching gas having no etching selectivity among the pattern, the first mask and the sacrificial layer. A lower portion of the pattern under the upper portion thereof is removed to divide the pattern into a plurality of pieces spaced apart from each other in the first direction.
