| titleOfInvention | Cleaning method and plasma processing apparatus |
| abstract | A cleaning method is provided. In the cleaning method, residues of elements of a group for a common semiconductor material in a chamber are removed with plasma of a halogen-containing gas. Residues of metal elements of groups 12 and 13 and groups 14 and 15 in the chamber are removed with plasma of a hydrocarbon-containing gas. A C-containing material in the chamber is removed with plasma of an O-containing gas. Further, the removing with the plasma of the halogen-containing gas, the removing with the plasma of the hydrocarbon-containing gas, and the removing with the plasma of the O-containing gas are performed in that order or the removing with the plasma of the hydrocarbon-containing gas, the removing with the plasma of the O-containing gas, and the removing with the plasma of the halogen-containing gas are performed in that order X times where X≥1. |
