Filed: 1991-09-18
Abstract: PURPOSE:To control adsorption of Ni and Cu to the surface of a wafer to be cleaned by a method wherein in the alkali cleaning process for the silicon wafer, a cleaning fluid doped with Al ions or Fe ions is used. CONSTITUTION:An alkali cleaning liquid, which consists of the mixed solution of H2O:H2O2:NH4OH=5:1:1 and is doped with Ni ions and Cu ions, is prepared is such a way that the concentrations of the Ni ions and the Cu ions respectively contain 0.1ppb. Moreover, Al ions and Fe ions are doped to the cleaning fluid by 1ppd.
