A chemical mechanical polishing apparatus includes a platen to hold a polishing pad, a carrier to hold a substrate against a polishing surface of the polishing pad during a polishing process, a dispenser to supply a polishing liquid to the polishing surface, and a temperature control system including a body configured to contact the polishing surface or the polishing liquid on the polishing surface. The body supports a thermal control module positioned over the polishing pad.

A break-in processing apparatus is disclosed, which can reliably perform a break-in process for an elastic membrane without reducing a utilization rate of a polishing apparatus. The break-in processing apparatus includes a stage to which an elastic membrane assembly including a carrier and an elastic membrane attached to the carrier is placed; a break-in determination module facing the elastic membrane placed to the stage; a fluid supply unit configured to supply a pressurized fluid into a pressure chamber formed between the outermost periphery portion of the elastic membrane and the carrier; and a controller configured to control operations of the break-in determination module and the fluid supply unit. The controller determines a completion of a break-in process of the elastic membrane based on a load applied to the break-in determination module by the elastic membrane which is expanded by the pressurized fluid supplied into the pressure chamber.

In an automatic wet sanding apparatus including a disc and a cushion pad, a disc center hole is formed at a central portion of the disc and a pad center hole is formed at a central portion of the cushion pad. Water having been supplied to an introduction space inside a skirt is stirred as an eccentric head rotates eccentrically and thereby pushed out toward a painted surface via the disc center hole and the pad center hole with enhanced pressure. Thus, sanding dust resulting from automatic wet sanding can be washed away toward an outer circumferential side by the water that is pushed out toward the outer circumferential side, so that the likelihood of clogging due to sanding dust can be reduced and high sanding efficiency can be maintained.

The present disclosure describes a method and an apparatus that can enhance the slurry oxidizability for a chemical mechanical polishing (CMP) process. The method can include securing a substrate onto a carrier of a polishing system. The method can further include dispensing, via a feeder of the polishing system, a first slurry towards a polishing pad of the polishing system. The method can further include forming a second slurry by enhancing an oxidizability of the first slurry, and performing a polishing process, with the second slurry, on the substrate.
