A solvent of a resist solution is dropped from a solvent supply nozzle onto the surface of a semiconductor wafer held by a spin chuck. The semiconductor wafer is rotated by the spin chuck to spread the resist solution over the entire surface of the semiconductor wafer W. Simultaneously, the resist solution is dropped from a resist solution supply nozzle onto the semiconductor wafer and spread following the solvent. During the processing, the processing space is isolated from the outer atmosphere by closing a lid of a processing vessel and a sprayed solvent is supplied into the processing space. The processing space is thus filled with the mist of solvent. In the processing space supplied with the solvent, evaporation of the solvent from the resist solution is suppressed. A film of the resist solution is formed with a uniform film thickness to the edge of the semiconductor wafer W.

Film forming method and film forming apparatus

A resist processing system includes a sensor connected for detecting the surface level of the processing solution contained in an intermediate tank, and a controller connected for controlling the fluid pressure on the basis of the surface level detected by the sensor.

Resist processing system having process solution deaeration mechanism

An apparatus for forming a coating film, comprises a spin chuck for supporting a substrate with one surface facing upward and rotating the substrate about a vertical axis, a first nozzle for supplying a solvent of a coating solution on the substrate, and a second nozzle for supplying the coating solution on a central portion of the substrate. The first and second nozzles are supported by a head such that the supported nozzle moves between a dropping position above the substrate and a waiting position offset from the substrate. The solvent and coating solution are diffused along the surface of the substrate by rotating the spin chuck.

Method of forming coating film and apparatus therefor

The present invention has a resist processing apparatus for supplying a processing solution onto an object to be processed to perform a resist process, including a processing solution supply nozzle for supplying the processing solution onto the object to be processed, a processing solution feeding arrangement for feeding the processing solution to the processing solution supply nozzle, a processing solution flow path arranged to extend between the processing solution feeding arrangement and the processing solution supply nozzle, and a processing solution deaeration mechanism arranged at an intermediate portion of the processing solution flow path to deaerate the processing solution. The processing solution deaeration mechanism includes a closed vessel, an inlet port for introducing the processing solution into the closed vessel, a member arranged in the closed vessel and having a gas-liquid separation function, and an evacuating arrangement for evacuating the interior of the closed vessel to deaerate the processing solution through the member having the gas-liquid separation function. Gaseous components are separated from the processing solution, and an outlet port feeds the processing solution, from which gaseous components are separated by the member having the gas-liquid separation function, to the processing solution supply nozzle.
