Abstract:
A method of repairing a non-continuous seed layer on a semiconductor substrate having a via or a trench, comprising the steps of:depositing a seed layer by physical vapor deposition to a thickness of 25 to 2000 Angstroms on the surface of the semiconductor substrate, wherein the semiconductor substrate comprises at least one via or one trench; coating the surface of the substrate with a solution including a reducing agent to cause a conformal layer of metal to deposit on a portion of the surface of the at least one via or one trench not covered by the seed layer; thereby repairing discontinuities in the seed layer in said at least one via or one trench deposited in said depositing step, said coating step being an electroless process; and performing an electroplating process on the substrate using the repaired seed layer.
