摘要:
In a process for making a semiconductor device, a first aqueous mixture is prepared and a fluorine-containing compound is combined with the first aqueous mixture to obtain an etchant composition. A sample of the etchant composition is taken and compared to a standard dilute solution of the fluorine-containing compound to obtain a value of fluorine-containing compound concentration in said sample. The value is input to a tank tool recipe control to cause an adjustment in the concentration of the fluorine-containing compound in the etchant composition. A surface of a semiconductor wafer can then be subjected to etching by the etchant composition.
