摘要： Provided are methods of forming patterns of semiconductor devices, whereby patterns having various widths may be simultaneously formed, and a pattern density may be doubled by a double patterning process in a portion of the semiconductor device. A dual mask layer is formed on a substrate. A variable mask layer is formed on the dual mask layer. A first photoresist pattern having a first thickness and a first width in the first region, and a second photoresist pattern having a second thickness greater than the first thickness and a second width wider than the first width in the second region are formed on the variable mask layer. A first mask pattern and a first variable mask pattern are formed in the first region, and a second mask pattern and a second variable mask pattern are formed in the second region, by sequentially etching the variable mask layer and the dual mask layer by using, as etch masks, the first photoresist pattern and the second photoresist pattern. First spacers covering side walls of the first mask pattern and second spacers covering side walls of the second mask pattern are formed. The first mask pattern is removed, and then the substrate is etched in the first region and the second region by using the first spacers as an etch mask in the first region, and the second mask pattern and the second spacers as an etch mask in the second region.

摘要： Disclosed are a method of manufacturing a non-slip plate and a non-slip plate manufactured thereby. The method includes preparing a base metal plate for joint design, washing and surface treatment, preparing a non-slip material, adhering the non-slip material to the bonding surface of the base metal plate to form a protrusion, and brazing the base metal plate having the non-slip material adhered thereto in a brazing furnace. The non-slip plate is applied to vehicles to impart non-slip performance thereto, and can be semi-permanently used.

摘要： Disclosed is a nozzle block applied to an electrospinning device. At least one piercing unit (means of piercing) having a diameter smaller than the inner diameter of a spinning nozzle is coaxially disposed inside the spinning nozzle in order to prevent solidification of a solution at a tip of the spinning nozzle. The present disclosure includes a first cleaning mechanism for cleaning the spinning nozzle by reciprocating the piercing unit and the spinning nozzle relative to each other so that the tip of the spinning nozzle is unclogged, and a second cleaning mechanism for cleaning aggregates deposited around and outside the tip of the spinning nozzle through chemical cleaning and/or physical cleaning when the electrospinning process is temporarily stopped or after the electrospinning process is completed.
