摘要： A method for producing a fluorine-containing polyimide film excelling in heat resistance, resistance to chemicals, water repellency, dielectric properties, electrical properties, and optical properties and a spin coater suitable for the method are to be provided. A method for the production of a fluorine-containing polyimide film which comprises forming a coating film of a fluorine-containing polyimide precursor in an atmosphere having a relative humidity thereof adjusted to a level of not more than 50 RH % and then subjecting the fluorine-containing polyimide precursor to heat treatment thereby forming a fluorine-containing polyimide film is provided. By adjusting the relative humidity in accordance with this method, the fluorine-containing polyimide precursor can be prevented from being decomposed by the absorption of moisture and consequently prevent effectively the fluorine-containing polyimide film from forming piriform spots and scratches. Further, by forming the coating film while keeping the coating film sprayed with a gas particularly during the course of spin coating thereby giving rise to a layer of air flow on the coating film, misty substances of the coating solution generated within the spin coater can be prevented from adhering again to the coating film and consequently ensure the production of a coating film of uniform quality. This formation of the layer of air flow can be facilitated by providing the spin coater with a lid and furnishing the lid with a gas feed port.
