Cleaning liquid for material comprising carbon-containing silicon oxide for wafer recycling, and cleaning method |
| abstract |
It is an object of the present invention to provide a cleaning solution for removing carbon-incorporated silicon oxide (SiOC) from the surface of a wafer in a step of producing a wafer having a material comprising the SiOC, and a cleaning method of using the same. The cleaning solution of the present invention comprises 2% by mass to 30% by mass of a fluorine compound, 0.0001% by mass to 20% by mass of a specific cationic surfactant that is an ammonium salt or an amine, and water, and has a pH value of 0 to 4. |
