The wafer is supported through an adhesive tape to an annular frame. The method includes removing the resin scattered onto the surface of the frame in forming the film on the wafer held on a spinner table, and this step further includes: rotating the spinner table; positioning a water nozzle above the frame held on the spinner table, supplying water from the nozzle to the frame, positioning an air nozzle adjacent to the water nozzle on the downstream side thereof in the rotational direction of the spinner table, and supplying air from the air nozzle against the flow of the water on the frame, whereby the water is forced to temporarily stay on the surface of the frame by the air supplied and is then expelled outward of the frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protective film forming method for forming a protective film on a wafer","description":"A method for forming a water-soluble resin film on a wafer having a plurality of devices thereon.
