发明名称 Charged particle beam apparatus, and article manufacturing method
摘要 A charged particle beam apparatus for processing an object using a charged particle beam includes a charged particle lens in which an array of apertures, through each of which a charged particle beam passes, is formed; a vacuum container which contains the charged particle lens; and a radiation source configured to generate an ionizing radiation; wherein the apparatus is configured to cause the radiation source to pass the ionizing radiation through the array of apertures in a state in which a pressure in the vacuum container is changing.

主权项 1. A charged particle beam apparatus for processing an object using a charged particle beam, the apparatus comprising: a charged particle optical element in which an array of apertures, through each of which a charged particle beam passes, is formed; a vacuum container which contains the charged particle optical element; and a radiation source configured to generate an ionizing radiation, wherein the apparatus is configured to cause the radiation source to pass the ionizing radiation through the array of apertures to irradiate a gas in the vacuum container with the ionizing radiation in a state in which a pressure in the vacuum container is changing.
