摘要:
Circuit elements, such as aluminum interconnects, and a protective film for protecting these circuit elements are formed on a surface of a semiconductor substrate. Resist is formed covering the protective film. The semiconductor substrate on which the resist covering the protective film is formed is dipped into pure water so as to allow the water to filter into a gap between the resist and semiconductor substrate. Then the semiconductor substrate having the resist thereon is dried in high temperature air, and the resist is adhered to the semiconductor substrate by a sticking function due to the surface tension generated when the water is decreasing. The semiconductor substrate to which the resist is adhered is cleaned by a hydrogen fluoride aqueous solution.
