Abstract:
A development method for processing a photo-resist layer deposited on a wafer, said photo-resist layer having a portion exposed by a light source, said development method comprising the steps of:distributing a developer over said photo-resist layer; developing said photo-resist layer and removing the light exposed portion of said photo-resist layer to form a photo-resist pattern; rinsing said photo-resist pattern and said wafer with purified water; covering said photo-resist pattern with a surfactant, wherein said surfactant is an anionic surfactant selected from the following group consisting of RfSO3NH4 (ammonium perfluoroalkyl sulfonates), RfCO2NH4 (ammonium perfluoroalkyl carboxylates), RfPO4NH4 (ammonium perfluoroalkyl phosphates) and ammonium perfluoroalkyl phosphates with hydrocarbon; and drying said wafer by spinning said wafer to remove water drops on a surface of said wafer.
