Title: Resist applying device
Inventor: ISHIKAWA HIDEKAZU
IPC: H01L21/027
Filed: 1990-09-10
Abstract: PURPOSE:To form the films in even thickness regardless of the kind of resist and the diameter of a semiconductor wafer by a method wherein the title resist applying device is provided with a holder holding a semiconductor wafer, a resist container containing a resist solution, a piping and a pump feeding the resist solution to the semiconductor surface while the holder, the resist container, the piping and the pump are contained in a refrigerator vessel. CONSTITUTION:The resist solution in a resist bottle 1 pumped up by a pump 3 is fed to the surface of a semiconductor wafer 5 through a piping 2. The semiconductor wafer holder 5a holding the semiconductor 5 is spinned by a motor 6 to spread the resist solution fed to the semiconductor wafer 5 thereby forming a thin film. Since the resist bottle 1, the pump 3 and the semiconductor wafer holder 5a are contained in a refrigerator box 8 to be refrigerated, the resist solution shall never pass into gel state. Through these procedures, the thickness of a resist film can be made even regardless of the kind of resist and the size of the semiconductor wafer.
