发明名称 MANUFACTURING METHOD OF SEMICONDUCTOR DEVICE
摘要 To improve the manufacturing yield of semiconductor devices. Over a semiconductor wafer, a film to be processed is formed; over that film, an antireflection film is formed; and, over the antireflection film, a resist layer is formed. Then, the resist layer is subjected to liquid immersion exposure, and a development and rinsing process to form a resist pattern. After that, the antireflection film and the film to be processed are etched sequentially using the resist pattern as an etching mask. In the development process of the resist layer, the antireflection film is exposed from parts from which the resist layer has been removed by the development process. When performing a rinsing process after the development, the water repellent property of the surface of the antireflection film exposed from the resist layer is not lower than the water repellent property of the surface of the resist layer.
