ABSTRACT:
A thin-film formation apparatus possesses a reaction chamber to be evacuated, a placing portion on which a substrate is placed inside the reaction chamber, a gas-dispersion guide installed over the placing portion for supplying a gas onto a substrate surface, a gas-supply port for introducing the gas into the gas-dispersion guide, a gas-dispersion plate disposed on the side of the substrate of the gas-dispersion guide and having multiple gas-discharge pores, a first exhaust port for exhausting, downstream of the gas-dispersion plate, the gas supplied onto the substrate surface from the gas-dispersion plate, and a second exhaust port for exhausting, upstream of the gas-dispersion plate, a gas inside the gas-dispersion guide via a space between the gas-dispersion guide and the gas-dispersion plate.
