Abstract: Provided is a method of fabricating a graphene nano device. The method includes forming a first metal mask pattern on a substrate on which a graphene layer is formed, and forming a graphene pattern by performing an etching process on the graphene layer using the first metal mask pattern as an etching mask. The forming of the first metal mask pattern includes forming a first adhesive layer on the graphene layer, disposing the first metal mask pattern prepared in advance on the first adhesive layer, and heating the first adhesive layer to attach the first metal mask pattern on the substrate.

Abstract: An apparatus for monitoring a laser welding bead irradiates a laser to a surface of a welding bead when welding with a laser welding machine, collects a signal reflected from the surface of the welding bead as an image signal, and then extracts at least one feature variable of a bead shape using the collected image signal. Then, the apparatus for monitoring the laser welding bead determines welding defects using the at least one feature variable, and controls an operation of the laser welding machine according to whether or not the welding defects are generated.
