  • Publication number: 20200269350
    Abstract: Disclosed is a nozzle unit for laser processing, which can implement one-touch coupling and separation, thereby enabling easy nozzle replacement and uniform maintenance of a nozzle in a mounted state at an accurate position while preventing damage to a nozzle joint. The nozzle unit for laser processing includes: a nozzle body including a nozzle hole and a coupling protrusion formed at an outer periphery of the nozzle hole; and a nozzle adapter allowing the nozzle body to be inserted into and coupled to a lower portion thereof and including a nozzle coupling portion allowing the coupling protrusion at a first position to be inserted thereinto or separated therefrom and allowing the coupling protrusion at a second position to be seated thereon, the second position being spaced apart from the first position in a circumferential direction of the nozzle hole.

  • Patent number: 10236442
    Abstract: Provided herein are methods of fabricating a magnetic memory device including forming magnetic tunnel junction patterns on a substrate, forming an interlayered insulating layer on the substrate to cover the magnetic tunnel junction patterns, forming a conductive layer on the interlayered insulating layer, patterning the conductive layer to form interconnection patterns electrically connected to the magnetic tunnel junction patterns, and performing a cleaning process on the interconnection patterns. The cleaning process is performed using a gas mixture of a first gas and a second gas. The first gas contains a hydrogen element (H), and the second gas contains a source gas different from that of the first gas.
