Abstract:
There is provided a cleaning method for removing a first deposit, formed on an upper electrode through an etching of a metal layer containing a metal, by using a plasma generated between a lower electrode of a lower structure and the upper electrode in a processing chamber of a plasma processing apparatus. The method includes a step of colliding ions with the first deposit formed on the upper electrode and a step of removing a second deposit, which is generated by said colliding and formed on the lower structure. Further, a cycle including the step of colliding and the step of removing is repeated multiple times.

Claim (Index 5):
The method of  claim 4 , wherein the metal layer is etched by a plasma of a gas containing hydrogen, a rare gas, and hydrocarbon,\n wherein the method further includes generating a plasma of an oxygen-containing gas in the processing chamber, and wherein said generating the plasma of the oxygen-containing gas is performed after the cycle is repeated multiple times.
