    • A pretreatment process, carried out prior to a developing process, spouts pure water, namely, a diffusion-assisting liquid for assisting the spread of a developer over the surface of a wafer, through a cleaning liquid spouting nozzle onto a central part of the wafer to form a puddle of pure water. The developer is spouted onto the central part of the wafer for prewetting while the wafer is rotated at a high rotating speed to spread the developer over the surface of the wafer. The developer dissolves the resist film partly and produces a solution. The rotation of the wafer is reversed, for example, within 7 s in which the solution is being produced to reduce the water-repellency of the wafer by spreading the solution over the entire surface of the wafer. Then, the developer is spouted onto the rotating wafer to spread the developer on the surface of the wafer.
    • 在显影过程之前进行的预处理过程,喷出纯水,即用于辅助显影剂在晶片表面上的扩散的扩散辅助液体,通过清洗液喷射喷嘴到达晶片的中心部分 形成一个纯净的水坑。 将显影剂喷射到晶片的中心部分以进行预润湿,同时晶片以高转速旋转以将显影剂铺展在晶片的表面上。 显影剂部分地溶解抗蚀剂膜并产生溶液。 晶片的旋转例如在7秒内相反,其中产生溶液以通过在晶片的整个表面上扩散溶液来降低晶片的拒水性。 然后,将显影剂喷射到旋转的晶片上,以将显影剂铺展在晶片的表面上。
