Drawing apparatus, and method of manufacturing article
First Claim
1. A drawing apparatus for performing drawing on a substrate with a charged particle beam, the apparatus comprising:
- a first member in which an aperture, through which the charged particle beam passes, is formed;
a chamber including a first space and a second space which are partitioned by the first member; and
a removing device including a first supply device configured to supply a first gas containing unsaturated hydrocarbon to the first space and a second supply device configured to supply a second gas containing ozone to the second space, and configured to remove contamination on the first member by active species generated by reaction of the first gas with the second gas.

16. A method of manufacturing an article, the method comprising:
-
performing drawing on a substrate using a drawing apparatus; developing the substrate on which the drawing has been performed; and processing the developed substrate to manufacture the article, wherein the drawing apparatus performs drawing on the substrate with a charged particle beam, and includes; a first member in which an aperture, through which the charged particle beam passes, is formed; a chamber including a first space and a second space which are partitioned by the first member; and a removing device including a first supply device configured to supply a first gas containing unsaturated hydrocarbon to the first space and a second supply device configured to supply a second gas containing ozone to the second space, and configured to remove contamination on the first member by active species generated by reaction of the first gas with the second gas.
