POLISHING COMPOSITION AND POLISHING METHOD USING SAME, AND SUBSTRATE MANUFACTURING METHOD

摘要

Provided is a polishing composition to be used for polishing an object including a conductor layer and an electrically conductive material layer that is in contact with the conductor layer. In a state in which the positive electrode and the negative electrode of an electrometer are connected to the electrically conductive material layer and the conductor layer, respectively, in the polishing composition at ordinary temperature, the current flowing from the positive electrode to the negative electrode has a positive value or is zero when the electrically conductive material layer and the conductor layer are polished. The polishing composition preferably contains a nitrogen atom-containing compound, a sulfur atom-containing compound, or a phosphorus atom-containing compound as an additive to control the value of the current to positive or zero.
