Abstract:
A method for an active energy beam irradiation, the method comprising:transporting a target object to be irradiated through a transport inlet of an irradiating chamber, irradiating the object in the chamber with an active energy beam in an active energy beam irradiating section under one of an inert gas and a reactive gas atmosphere, and transporting the object out of the irradiating chamber through a transport outlet of the irradiating chamber, wherein a gas flow resistance at each of the transport inlet and the transport outlet is controlled by a gas flow resistor provided in at least one of the transport inlet and the transport outlet to meet the condition of X/Y&gE;1, where X represents an amount of the gas passing through the transport inlet, and Y represents an amount of the gas passing through the transport outlet, and wherein the active energy beam irradiation is carried out under a state meeting the condition of X/Y&gE;1.
