Patent ID: 10818483

Abstract:
An object of the invention is to reduce sizes of an inert gas supply and exhaust devices used for a pulse sputtering device. Another object is to efficiently supply suitable quantity of the inert gas to a place where the inert gas is required in the pulse sputtering device. Therefore, a provided pulse sputtering device has a sputtering source that performs pulse discharge and generates plasma, a gas injection valve that injects and supplies an inert gas to the sputtering source and a controller that controls the sputtering source and the gas injection valve. The controller controls the sputtering source and the gas injection valve such that the gas injection valve injects the inert gas intermittently and such that a part of a period, in which the pulse discharge occurs in the sputtering source, overlaps with a part of a period, in which the gas injection valve injects and supplies the inert gas.
