Abstract:
A substrate suction stage including a substrate support unit having a top surface, a cavity formed therein, an ejection hole formed therein and extending from the cavity to the top surface, and a suction hole formed therein for connecting the ejection hole and the top surface, and a gas supply unit for supplying gas into the cavity, wherein the ejection hole surrounds the suction hole in plan view, and when gas is supplied into the cavity, gas in the suction hole is discharged to the outside via the ejection hole.

Claim (Index 8):
A substrate treatment method comprising:\n placing a substrate on a top surface of a substrate support unit; and performing a liquid treatment on the substrate while, by supplying gas from one gas supply unit into a cavity inside the substrate support unit, the gas is sprayed from an ejection hole intercommunicating with the cavity to a peripheral portion of a back surface of the substrate, and gas is discharged from a suction hole for connecting the top surface of the substrate support unit and the ejection hole, thereby causing the substrate to be sucked on the substrate support unit.
