Abstract

A semiconductor treatment apparatus has a gas-phase decomposing device for decomposing a gas-phase on a surface of a semiconductor substrate, a substrate supporting device for supporting the substrate, and a substrate transfer device for transferring the substrate between the gas-phase decomposing device and the substrate supporting device. The apparatus further has a liquid-drop applicator for applying a liquid-drop on the surface of the substrate supported by the substrate supporting device, with the liquid-drop being brought into contact with the surface of the substrate, and a liquid-drop preserving device for preserving the liquid-drop that has been applied to the surface of the substrate.
