    摘要: A lithographic apparatus includes an illumination system for conditioning a beam of radiation, and an article support for supporting a substantially flat article to be placed in a beam path of the beam of radiation. The article support includes a plurality of supporting protrusions that define a support zone for providing a substantially flat plane of support. The apparatus also includes a backfill gas feed for providing an improved thermal conduction between the article and the article support. The backfill gas feed includes a backfill gas discharge zone for feeding backfill gas to a backside of the article when supported by the article support. The backfill gas discharge zone substantially encloses the support zone.
