A wafer treatment apparatus includes a wafer supporter for supporting and rotating a wafer, a frontside liquid discharger for discharging a liquid toward a frontside of the wafer, a backside liquid discharger for discharging the liquid toward a backside of the wafer, a treatment chamber for accommodating the wafer supporter, and including liquid collecting inlets stacked on each other and receiving the liquid discharged from at least one of the frontside and backside liquid dischargers, and a controller for controlling a height of an upper end of a first liquid collecting inlet of the liquid collecting inlets to have one of a first height in a process of discharging the liquid to the backside of the wafer adjacent to the wafer supporter and a second height, lower than the first height, in a process of discharging the liquid to the frontside of the wafer.

Wafer treatment apparatus and method for reducing scattering of treatment liquid

The inventive concept provides a support unit for supporting a substrate. The support unit includes a support plate that has an interior space and on which the substrate is placed, a heating member that is provided in the interior space and that heats the substrate placed on the support plate, a heat insulating plate provided in the interior space and disposed under the heating member, a reflective plate provided in the interior space and disposed under the heat insulating plate, and a heat dissipation plate provided in the interior space and disposed under the a reflective plate.

Support unit, substrate treating apparatus including the same, and substrate treating method

A substrate treating liquid recovery unit with improved cleaning efficiency and a substrate treating apparatus including the same are provided. The substrate treating apparatus includes a substrate support unit; and a substrate treating liquid recovery unit surrounding the substrate support unit, for recovering a substrate treating liquid, and including a first recovery container, wherein the first recovery container comprises a first base for discharging the substrate treating liquid to an outside through a first recovery line, and including a third portion disposed on one side of the substrate support unit and a fourth portion disposed on the other side of the substrate support unit; a first sidewall extending upwardly from one end of the first base; a first upper plate extending obliquely and upwardly from an end of the first sidewall; and a first inner wall extending upwardly from the other end of the first base.

Unit for recycling treating liquid of substrate and apparatus for treating substrate with the unit

Disclosed is a support unit for supporting a substrate. The support unit includes a support plate having an inner space defined therein, a heating member disposed in the inner space and emitting light for heating the substrate supported on the support unit, and a reflective member disposed along an edge region of the support plate and reflecting thermal energy of the light to an edge region of the substrate supported on the support unit.

An apparatus for treating a substrate includes a process chamber having a treatment space defined therein, a support unit for supporting the substrate in the treatment space, a liquid supply unit for supplying treating liquid to the substrate supported on the support unit, and a heating unit disposed in the support unit for heating the substrate supported on the support unit, wherein the heating unit includes a plurality of lamps to heat the substrate, and a window disposed above the lamps to transmit light emitted from the lamps, wherein the window includes a base in a form of a plate, and light adjustment means formed on the base to spread or converge light emitted from the lamps.
