Abstract:
1. A supplying system of adding a gas into a polishing slurry, which is applicable to a planarization process apparatus to be used in a substrate, for polishing the substrate, the supplying system comprising: a slurry container, for storing the polishing slurry; a gas-mixed container connected to the slurry container, for receiving the polishing slurry; a gas container, for storing the gas and transporting the gas to the gas-mixed container; an adjusting device connecting the gas-mixed container to the gas container, for controlling the gas container to transport the gas with a predetermined flow rate to the gas-mixed container; and a first flow controller connected to the gas-mixed container, for controlling the gas-mixed container to output a gas-mixed polishing slurry into the planarization process apparatus to allow the planarization process apparatus for polishing the substrate by using the supplying system when the gas is dissolved in the polishing slurry to form the gas-mixed polishing slurry, wherein a solubility of the gas in the polishing slurry of the supplying system is positively related to a partial pressure of the gas in the polishing slurry, and the gas in the gas-mixed polishing slurry serves as main reaction gas for the substrate during the planarization process to increase a removal rate of the substrate.
