Sputtering device

摘要

A sputtering device that efficiently guides sputtering particles ejected from a target to a film deposition subject and prolongs the interval at which a stick preventive member requires replacement. The sputtering device 1 has a vacuum chamber in which a specified sputtering target is placed so as to face a substrate 4 that is also placed in the vacuum chamber 2, and deposits a film on a surface of the substrate 4 using sputtering particles 20 ejected from the sputtering target 6; and particle ejection sections 60 constructed so as to slope at a specified angle of 30° to 60° with respect to the surface of the substrate 4, and respectively facing each other in the shape of a funnel are provided on the sputtering target 6. Lines of magnetic force 13 run from an N pole of a magnet 7a arranged at a rear surface of the target 6 to an S pole of a magnet 7b arranged around the target 6.
