    • PURPOSE: An apparatus for coating photoresist on a substrate is provided to reduce inferiority by preventing spots generated during a photoresist coating process by cooling the temperature of the gas discharged to a discharge channel of a floating stage. CONSTITUTION: An apparatus for coating photoresist on a substrate comprises: a worktable; a transport unit which is installed on the top of a worktable and includes plural floating stages transferring a substrate(G); a slit nozzle which is installed at the upper side of the worktable and applies photoresist on the substrate; a floating gas unit(18) for supplying the gas to the floating stage; and a temperature controller(19) for adjusting the temperature of the air supplied to the floating stage.
    • 目的:提供一种用于在基板上涂覆光致抗蚀剂的设备,以通过冷却喷射到浮动级的排放通道的气体的温度来防止在光致抗蚀剂涂覆过程中产生的斑点来降低劣质。 构成:用于在衬底上涂覆光致抗蚀剂的设备包括:工作台; 传送单元,其安装在工作台的顶部,并且包括传送基板(G)的多个浮动台。 狭缝喷嘴,其安装在工作台的上侧并在基板上施加光致抗蚀剂; 用于将气体供应到浮动级的浮式气体单元(18); 以及用于调节供应到浮动级的空气的温度的温度控制器(19)。
