Abstract
A process for monitoring an electroless plating bath to determine whether it is in a take mode by electrolessly depositing a film of the metal of the plating bath onto a substrate to provide a preplated cathode; providing the cathode, a reference electrode, and an anode in the electroless bath; passing an electric current and varying the voltage difference, plotting the voltage difference versus the current; and comparing the oxidation peak of the reducing agent to the oxidation peak of the reduced state of the metal ion to be plated to thereby determine whether the bath is in a take mode.
