    摘要: The present disclosure describes an apparatus for chemical-mechanical polishing of a semiconductor wafer. Some embodiments of the present disclosure include a pad, a slurry introduction mechanism, a wafer carrier (e.g., carrying a wafer being polished by the chemical-mechanical polishing system), a pad conditioner, and a pad cooling mechanism. The pad cooling mechanism of the present disclosure may apply a liquid or gas to the pad (e.g., to an upper surface of the pad) to control the temperature of the pad as the chemical-mechanical polishing process occurs. As a result, the temperature of the pad may be maintained at a safe and operable level for an extended period of time during chemical-mechanical polishing of a wafer.
