Patent ID: 6893548

Claim:
A method of adjusting an electrochemical bath for an electrochemical deposition process, comprising: a) providing a first copper electroless bath having a first bath composition; b) utilizing a portion of the first copper electroless bath in an electroless deposition process to form a second copper electroless bath having a second copper electroless bath composition comprising one or more generated constituents; c) identifying at least some of the one or more generated constituents by determining the first and second copper electroless bath compositions, wherein identifying at least some of the one or more constituents generated during the electrochemical deposition process comprises: (i) analyzing a portion of the first copper electroless bath to determine the first bath composition; (ii) analyzing a portion of the second copper electroless bath to determine the second bath composition; and (iii) comparing the first and second copper electroless bath compositions to identify at least some of the one or more constituents generated in the electroless deposition process; and d) adding an additive material having a composition that is substantially the same as at least some of the one or more generated constituents to a third copper electroless bath to form a fourth copper electroless bath.
