titleOfInvention |
Method for polishing wafer |
abstract |
A wafer is polished by performing a chemical reaction to change a property of a first portion of a material layer on the wafer using a first chemical substance. A first rinse is performed to remove the first chemical substance and retard the chemical reaction. A mechanical polishing process is then performed to remove the first portion of the material layer. |
