Abstract: PURPOSE: A spin coating apparatus is provided to prevent a residual liquid material from backwardly flowing to a substrate when the substrate rotates, by forming a tray cover of a cone type and by connecting the tray cover to a tray. CONSTITUTION: A cover part forms an inner space capable of being coated, detachably coupled to a case. A substrate to coat is mounted on a chuck, installed in the inner space. A drive unit makes the substrate rotate at a desirable speed, coupled to the chuck. A path through which the liquid material on the substrate passes is formed near the substrate. A tray unit includes the tray cover(330) and the tray(320). The tray cover has an inclined wall surface and a space where the substrate is received. The tray is correspondingly coupled to the tray cover.
