发明名称 Drawing apparatus, method of manufacturing article, and processing apparatus
摘要 A drawing apparatus which performs drawing on a substrate with a plurality of charged particle beams includes: a blanking deflector located in a vacuum chamber and configured to blank each of the plurality of charged particle beams; a device located in an external chamber in which a gas pressure is higher than a gas pressure in the vacuum chamber, and configured to control the blanking deflector; and a first substrate facing the blanking deflector. The first substrate constitutes a partition which separates the vacuum chamber and the external chamber in a region, of the first substrate, facing the blanking deflector, and includes an electrode which fills a via formed in the region. The device is electrically connected to the blanking deflector via the electrode.
