Classification: CPC H | IPC H

Claim 0:
1. A semiconductor substrate treatment system, comprising:
a chamber having an internal space defined by a first surface of the chamber, a second surface of the chamber thereabove and opposing the first surface, and a third surface of the chamber connected to the first surface and the second surface;
a transfer device in a central region of the internal space, the transfer device including an arm, the transfer device configured to transfer a semiconductor substrate;
an ionizing device including a plurality of discharge devices that each include an electrode,
the plurality of discharge devices including a first discharge device, a second discharge device, and a third discharge device,
the first discharge device and the second discharge device on the second surface and configured to emit ions having a first polarity and a second polarity, respectively,
the second polarity being opposite to the first polarity,
the ionizing device configured to charge particles in the internal space with the first polarity and the second polarity,
the third discharge device above the transfer device and configured to emit the ions having the first and second polarities together to neutralize a charge generated on a surface of the transfer device; and

a first dust collecting assembly and a second dust collecting assembly on the third surface and facing each other,
the first dust collecting assembly and the second dust collecting assembly being configured to collect charged particles by generating electric fields having different polarities,
the first dust collecting assembly and the second dust collecting assembly being adjacent to the first discharge device and the second discharge device, respectively, and
the first dust collecting assembly and the second dust collecting assembly having the second polarity and the first polarity, respectively, wherein

the first dust collecting assembly and the second dust collecting assembly include a particle collecting layer configured to have the charged particles attach thereto, and
the arm moves within an area corresponding to a lower portion of the third discharge device.
