A low surface tension liquid is supplied from a low surface tension liquid supplying unit to a heated substrate to replace a processing liquid by the low surface tension liquid. The heating of the substrate is weakened and the low surface tension liquid is supplied from the low surface tension liquid supplying unit to the substrate, so that a liquid film of the low surface tension liquid is formed. The liquid film on the substrate is removed by strengthening the heating of the substrate without supplying the low surface tension liquid from the low surface tension liquid supplying unit to a central region of the substrate.

Substrate processing apparatus and substrate processing method

A substrate processing method includes a rinse liquid supplying step of supplying a rinse liquid containing water to a major surface of a substrate, a rotating step of rotating the substrate around a rotation axis passing through a central portion of the major surface of the substrate, and a hydrophobizing agent supplying step of supplying a hydrophobizing agent containing a first dissolving agent to the major surface of the substrate to replace a liquid held on the major surface of the substrate with the hydrophobizing agent in parallel with the rotating step after the rinse liquid supplying step is performed, and the hydrophobizing agent supplying step includes a hydrophobizing agent discharging step of discharging a continuous flow of the hydrophobizing agent from a discharge port of a nozzle toward the major surface of the substrate held by a substrate holding unit with a Reynolds number at the discharge port being not more than 1500.

Substrate processing method and substrate processing apparatus

A substrate processing method including a center portion discharging step of discharging a low-surface-tension liquid from a first low-surface-tension liquid nozzle disposed above a substrate toward the center portion of an upper surface, an inert gas supplying step of supplying inert gas to above the substrate in parallel with the center portion discharging step in order to form a gas flow flowing along the upper surface, and a peripheral edge portion discharging and supplying step of discharging the low-surface-tension liquid from a second low-surface-tension liquid nozzle disposed above the substrate toward a peripheral edge portion of the upper surface in parallel with the center portion discharging step and the inert gas supplying step.

Substrate processing method and substrate processing device

A substrate processing method includes a cleaning processing step, a mixed organic solvent supplying step, and a fluorine organic solvent supplying step. The cleaning processing step is a step of cleaning a main surface of a substrate by supplying deionized water to the substrate. The mixed organic solvent supplying step is a step of supplying a fluid of a mixed organic solvent to the main surface of the substrate after the cleaning processing step. The fluid of the mixed organic solvent contains a fluid of a water-soluble organic solvent and a fluid of a fluorine organic solvent having a smaller surface tension than that of the deionized water and a lower water solubility than that of the fluid of the water-soluble organic solvent. The fluorine organic solvent supplying step is a step of supplying the fluid of the fluorine organic solvent to the main surface of the substrate without supplying the fluid of the water-soluble organic solvent after the mixed organic solvent supplying step.

A substrate treatment apparatus for removing an unnecessary substance from a surface of a substrate. The apparatus is provided with: an oxidation liquid supply mechanism for supplying an oxidation liquid having an oxidative effect to the substrate surface; a physical cleaning mechanism for physically cleaning the substrate surface; and an etching liquid supply mechanism for supplying an etching liquid having an etching effect to the substrate surface. It is preferred to physically clean the substrate surface while supplying the oxidation liquid to the substrate surface.

Substrate treatment apparatus and substrate treatment method

A blocking plate is disposed to face a substrate which is held by substrate holding device. A processing fluid is supplied to a surface of the substrate while supplying inert gas into a space between the substrate and the blocking plate. Since the inert gas flows along the surface of the substrate within the space between the substrate and the blocking plate, no turbulence which whirls upward is created at the surface of the substrate. This prevents the pollutants from adhering to the substrate and improves the quality of the substrate.

Method of and apparatus for processing substrate

A substrate processing apparatus adapted to properly perform a substrate scrubbing process with the use of a scrubbing member. The apparatus includes a retention member for retaining a scrubbing member for scrubbing a substrate and a vertical drive mechanism for vertically moving the retention member. The state of the scrubbing member and the vertical position of the retention member are sensed, and a vertical position of the retention member suitable for the scrubbing of the substrate is determined on the basis of the results of the sensing. Then, the retention member is moved to the position thus determined.
