Patent ID: 8808970

Claim:
A manufacturing method of a semiconductor device, comprising the steps of: (a) providing a semiconductor substrate; (b) forming a first material film over the semiconductor substrate; (c) forming a resist layer over the first material film; (d) subjecting the resist layer to liquid immersion exposure; (e) after the step (d), subjecting the resist layer to a development process; (f) after the step (e), subjecting the semiconductor substrate to a rinsing process with a rinse liquid; (g) after the step (f), rotating the semiconductor substrate to dry the semiconductor substrate; and (h) after the step (g), etching the first material film using the resist layer as an etching mask, wherein in the step (e), the first material film is exposed from a part from which the resist layer has been removed by the development process, when performing the step (f), a water repellent property of a surface of the first material film exposed from the resist layer is not lower than a water repellent property of the surface of the resist layer, and wherein the first material film is an organic film containing carbon as a main component or an organic film containing carbon and silicon as main components, and, in the step (b), a chemical solution for forming the first material film contains a fluororesin and the first material film in which the fluororesin has segregated over the surface is formed by applying the chemical solution to the semiconductor substrate.
