Abstract
There is provided a drying apparatus for covering an upper surface of the substrate with an uneven pattern formed thereon with a liquid film and subsequently drying the substrate, including: a first heat transfer part whose temperature is adjusted to a first temperature, wherein a first heat is transferred between the first heat transfer part and the substrate by a first temperature difference; a second heat transfer part whose temperature is adjusted to a second temperature different from the first temperature, wherein a second heat is transferred between the second heat transfer part and the substrate by a second temperature difference; and a controller configured to control the first temperature and the second temperature and to control a surface tension distribution of the liquid film so as to control an agglomeration of the liquid film.
