Hence in a state that the substrate W in the HFE is exposed to the air, the majority of the HFE stuck to the substrate already vaporizes and then the fine pattern is not loaded by the surface tension of the HFE. Consequently, the fine pattern is prevented from being collapsed due to the surface tension of the HFE.  <P>COPYRIGHT: (C)2011,JPO&INPIT
