Provided is a fabricating method of a pattern, which includes preparing a first substrate having a first width and a first thickness, stretching the first substrate and preparing a second substrate having a second width and a second thickness, forming a base layer made of a material of a pattern which will be formed on the second substrate, removing a predetermined region of the base layer and forming a first pattern having a first line width and a first height on the second substrate, and removing a tensile force applied to the second substrate to restore the second substrate back to being the first substrate and forming a second pattern having a second line width and a second height on the first substrate. Fineness of a line width can be achieved by forming the first pattern in a state in which the substrate is stretched, contracting a line width of the first pattern while restoring the stretched substrate, and forming the second pattern having a contracted line width on the restored substrate such that high integration can be achieved.

Fabricating method of a pattern including stretching a substrate

The present invention relates to a welding device which includes a welding power source provided with a power supply circuit; a wire feeder connected to the welding power supply to supply wire; a torch which pulls the wire supplied from the wire feeder and supplies the wire to a welding part; an IR thermal camera which captures the welding part; a vision module having built-in program which receives and processes a captured image of a IR thermal camera; and a slag removal device which removes slag detected in the welding part in real time in conjunction with the vision module. The welding device has an effect in which slag generated during welding can be removed before the slag is fixed on the molten pool.

Provided is a printing apparatus including: a printing roller whose outer circumferential surface is coated with ink; a clich&#xe9; roller which rotates in engagement with the printing roller and forms first patterns on the printing roller by removing portions of the ink coated on the outer circumferential surface of the printing roller and on which second patterns which are the removed portions of the ink are formed; a first transfer substrate onto which the first patterns of the printing roller are transferred; and a second transfer substrate onto which the second patterns of the clich&#xe9; roller are transferred. The printing apparatus can reduce the time required for a product production process by omitting a clich&#xe9; cleaning process.
