Abstract:
A method for applying a resin film to the face of a semiconductor wafer, comprising: an assembly holding step of holding an assembly on the surface of chuck means, with the back of the assembly being opposed to the surface of the chuck means, the assembly including a frame having a mounting opening formed in a central portion of the frame, and a semiconductor wafer mounted in the mounting opening of the frame by sticking a mounting tape to the back of the frame and the back of the semiconductor wafer; a liquid droplet supply step of supplying liquid droplets of a solution having a resin dissolved therein onto the face of the semiconductor wafer in the assembly after the assembly holding step; and a spreading step of rotating the chuck means subsequently to the liquid droplet supply step, thereby spreading the liquid droplets throughout the face of the semiconductor wafer. The method further comprises a cleaning step of rotating the chuck means and also supplying a cleaning fluid to the surface of the frame after the spreading step, thereby cleaning the solution which has adhered to the surface of the frame.
