Patent ID: 8287333

Claim:
A single type substrate treating apparatus comprising: a process chamber in which a substrate treating process is performed; a substrate supporting unit rotatably disposed in the process chamber for placing a substrate on the substrate supporting unit; a polishing unit disposed in the process chamber at a side of the substrate supporting unit for polishing the substrate chemically and mechanically, the polishing unit further including a polishing head on which a polishing pad is mounted to polish the substrate, a first driving member configured to rotate the polishing head on a center of the polishing head, a second driving member configured to move the polishing head on a horizontal pane, and a third driving member configured to move the polishing head upward and downward, wherein the polishing head further includes a housing having a cylindrical shape with an opened bottom side, a polishing pad holder disposed at the opened bottom side of the housing for coupling with the polishing pad, a vertically extendable bellows disposed on a top surface of the polishing pad holder, and a pneumatic member configured to apply an air pressure to the bellows, the second driving member further includes a swing arm having an end horizontally coupled to the housing, a vertical arm vertically coupled to the other end of the swing arm, and a second driving motor configured to provide rotation power to the vertical arm, and the third driving member further includes a supporting block configured to rotatably support the vertical arm, and a linear driving unit configured to linearly move the supporting block upward and downward; and a cleaning unit disposed in the process chamber at another side of the substrate supporting unit for cleaning the substrate.
