    • A joint nozzle that delivers a developer, a rinsing liquid and nitrogen gas is disposed adjacent the spin center of a substrate in plan view. A controller operates electromagnetic switch valves to continue supply of the developer, while spinning the substrate, in a developing process, and to start supply of the rinsing liquid in a rinsing process, immediately after the supply of the developer ends, thereby achieving a shortened period of the developing process. A switching is made to a drying process by starting supply of the nitrogen gas immediately after completion of the rinsing process. Thus, even if the substrate has a large angle of contact, formation of droplets of the rinsing liquid is inhibited to prevent post-develop defects.
    • 在平面图中,与基板的旋转中心相邻地设置输送显影剂,冲洗液和氮气的接合喷嘴。 控制器在显影过程中操作电磁切换阀以继续供应显影剂,同时旋转基底,并且在显影剂供应结束后立即在漂洗过程中开始供应冲洗液,从而实现缩短的周期 的发展过程。 通过在完成漂洗处理之后立即开始供应氮气,进行干燥过程的切换。 因此,即使基板具有大的接触角,也可以抑制漂洗液的液滴的形成,防止显影后的缺陷。
