Classification: CPC H  B | IPC B  H

Claim 4:
5. A substrate treating apparatus, comprising:
a supporting portion configured to contact a substrate to support the substrate in a horizontal posture;
a transport mechanism configured to transport the substrate to the supporting portion; and
a reversing mechanism configured to receive the substrate from the supporting portion, to reverse the substrate, and to deliver the substrate to the supporting portion,
the transport mechanism including:
a first suction portion configured to suck the substrate without contacting the substrate; and
a transport driving unit including a first hand configured to engage and move the first suction portion,
the reversing mechanism including:
a second hand including a second suction portion configured to suck the substrate without contacting the substrate; and
a hand driving unit including a rotation driving unit configured to rotate the second hand with the second suction portion around a horizontal rotation axis, wherein
when the transport mechanism transports a substrate to the supporting portion, the first suction portion is located above the substrate and sucks the substrate upward while causing gas to flow along a top face of the substrate and the transport driving unit moves the first suction portion to the supporting portion,
when the reversing mechanism receives the substrate from the supporting portion, the second suction portion is located above the substrate supported by the supporting portion and sucks the substrate upward while causing gas to flow along a top face of the substrate;
the rotation driving unit moves the second suction portion between a first position where the second suction portion blows gas downward and a second position where the second suction portion blows gas upward by rotating the second suction portion around the rotation axis;
the reversing mechanism includes:
a movement driving unit configured to move the second suction portion from the first position to a third position where no interference is made with the transport mechanism, and
the second suction portion is located at the third position when the transport mechanism delivers the substrate to the supporting portion; and
the second suction portion is positioned more radially outward of the substrate, supported by the supporting portion, than the supporting portion in plan view when the second suction portion is located at the third position.
