Abstract:
1. A processing device, comprising: a single processing chamber provided with a support member for supporting a substance to be processed; an electron beam source that is provided in said processing chamber and emits an electron beam toward the substance to be processed supported by said support member; an emission gas supply system having an emission gas supply line to said processing chamber and which supplies an emission gas that emits UV light upon receiving an electron beam, a process gas supply system having a process gas supply line to said processing chamber and which supplies a process gas, said process gas supply line being separate from said emission gas supply line; and a low pressure system that reduces the pressure in said processing chamber and that is attached to an exhaust outlet which is formed in the processing chamber at a height below a sample platform of the support member which supports the substance to be processed against a downstream flow of the emission gas or the processing gas, wherein the electron beam processing is carried out by operating the low pressure system to put an inside of the processing chamber into a certain reduced pressure state, and in this reduced pressure state directly irradiating an electron beam from the electron beam source onto the substance to be processed in order to carry out electron beam processing on the substance to be processed, wherein the UV processing is carried out by creating an emission gas atmosphere of a certain pressure in the processing chamber, and in this emission gas atmosphere operating the electron beam source such that the emission gas is excited upon receiving an electron beam to emit UV light, and processing is carried out on the substance to be processed by this emitted UV light, and wherein the specific processing is carried out by creating a processing gas atmosphere of a certain pressure in the processing chamber, and in this processing gas atmosphere operating the electron beam source such that the processing gas is activated or decomposed upon receiving an electron beam to produce active species, and processing is carried out on the substance to be processed by the active species.
