Abstract

PURPOSE:To work a diffusion material in an SOG liquid to a semiconductor wafer, and to improve reliability by positioning a liquid supply section dripping the SOG liquid to the semiconductor wafer into a chuck cover. CONSTITUTION:The liquid supply section 5a of a pipe 5 dripping an SOG liquid to a semiconductor wafer 2 is positioned into a chamber 11a for a chuck cover 11. A dry gas is fed into the chamber 11a from a gas introducing port 12 when a film is applied onto the semiconductor wafer 2, thus forming the periphery of a rotary chuck 1 in a low-humidity atmosphere. Consequently, the reaction of a diffusion material included in the SOG liquid 4 and H2O can be inhibited positively when the film is applied. Accordingly, sufficient diffusion material in the SOG liquid can be worked to the semiconductor wafer when the film is shaped, thus improving reliability on the quality of the wafer.
