Abstract:
PURPOSE: A liquid processing method and apparatus, and a recording medium recording a program for executing the liquid processing method are provided to eliminate a titanium element in a short time by supplying processing liquids having different etching rate. CONSTITUTION: A substrate supported in a supporting part is rotated with a supporting part. First processing liquid including hydrofluoric acid is provided to the rear side of the rotated substrate(S11). The rear side of the substrate is processed by the first processing liquid. Second processing liquid including ammonium hydrogen peroxide is provided to the rear side of the rotated substrate(S12). The rear side of the substrate is processed by the second processing liquid. DeIonized water is supplied to the bottom side of the substrate(S13). The substrate is dried(S14).
