Abstract
An imprint apparatus performs pressing of an imprint material on a substrate with a mold to form a pattern on the substrate. The imprint apparatus includes a supply device configured to supply a condensable gas to a space between the imprint material and the mold. The condensable gas is liquefied by the pressing. The apparatus further includes a pipe for transferring the condensable gas in a gas state to the supply device and a storage connected to the pipe. The storage stores the condensable gas in a liquid state. The supply device is configured to supply the condensable gas vaporized in the storage and transferred through the pipe from the storage.
