摘要： Disclosed is an ALD device in which a shower head is disposed at a position opposed to a film formation surface of a target workpiece in a chamber and has raw material gas ejection ports and OH* forming gas ejection ports alternately arranged at predetermined intervals in two film-formation-surface directions so as to face the film formation surface. The OH* forming gas ejection ports respectively include first ejection ports for ozone gas ejection and second ejection ports for unsaturated hydrocarbon gas ejection. An oxide film is formed on the film formation surface by ejecting a raw material gas from the raw material gas ejection ports and ejecting an ozone gas and an unsaturated hydrocarbon gas from the first and second ejection ports of the OH* forming gas ejection ports, respectively, while moving the target workpiece along the two film-formation-surface directions.
