  • Publication number: 20130133695
    Abstract: A chemical liquid process is performed on a substrate. Then, a rinse process that supplies a rinse liquid to the substrate is performed. Thereafter, a drying process that dries the substrate is performed while rotating the substrate. The drying process includes a first drying process that rotates the substrate at a first rotational speed; a second drying process that decreases the rotational speed of the substrate to a second rotational speed lower than the first rotational speed after the first drying process. In the second drying process, the rinse liquid and a drying solution are agitated and substituted while generating braking effect. In a third drying process, the rotational speed of the substrate is increased from the second rotational speed to a third rotational speed after the second drying process. Thereafter, in a fourth drying process, the drying solution on the substrate is scattered away by rotating the substrate.

    Abstract: Methods and apparatuses are disclosed for rinsing the interface area of a liquid and air boundary after a substrate cleaning process using gas barrier. In some embodiments, a protective chuck having an inner gas ring and an outer liquid ring can be used to clean the area under the edge of the protective chuck. A gas flowing outward from the gas ring can enable a liquid to flow outward from the liquid ring, rinsing the outer portion of the protective chuck. The interface rinsing process can enable combinatorial processing of a substrate, providing multiple isolated processing regions on a single substrate with different material and processing conditions.

  • Patent number: 8449684
    Abstract: The present invention provides a substrate cleaning method capable of removing particles from the entire surface of a substrate to be processed at a high removing efficiency. In the substrate cleaning method according to the present invention, a substrate to be processed W is immersed in a cleaning liquid in a cleaning tank 12. Then, ultrasonic waves are generated in the cleaning liquid contained in the cleaning tank 12, so that the substrate W is subjected to an ultrasonic cleaning process. The step of generating ultrasonic waves includes a step of generating ultrasonic waves in the cleaning tank while the cleaning liquid is being supplied into the cleaning tank. A supply rate at which the cleaning liquid is supplied into the cleaning tank at a certain timing in the step of generating ultrasonic waves differs from a supply rate at which the cleaning liquid is supplied into the cleaning tank at another timing in the step of generating ultrasonic waves.

  • Publication number: 20130084709
    Abstract: In a substrate processing apparatus, an anti-static liquid supply part supplies the anti-static liquid having electrical resistivity higher than that of an SPM liquid onto a substrate to puddle an entire upper surface of the substrate with the anti-static liquid, to thereby gradually remove static electricity from the substrate. Then, the processing liquid supply part supplies the SPM liquid onto the substrate to thereby perform an SPM process. In the SPM process, it is thereby possible to prevent a large amount of electric charges from rapidly moving from the substrate to the SPM liquid and prevent any damage to the substrate. Further, by maintaining the electrical resistivity of the anti-static liquid at the target electrical resistivity, it is possible to increase the static elimination efficiency of the substrate and shorten the time required for the static elimination process within the limits of causing no damage to the substrate.

  • Patent number: 8377219
    Abstract: A method for cleaning a semiconductor wafer composed of silicon directly after a process of chemical mechanical polishing of the semiconductor wafer includes transferring the semiconductor wafer from a polishing plate to a first cleaning module and spraying both side surfaces of the semiconductor wafer with water at a pressure no greater than 1000 Pa at least once while transferring the semiconductor wafer. The semiconductor wafer is then cleaned between rotating rollers with water. The side surfaces of the semiconductor wafer are sprayed with an aqueous solution containing hydrogen fluoride and a surfactant at a pressure no greater than 70,000 Pa. Subsequently, the side surfaces are sprayed with water at a pressure no greater than 20,000 Pa. The wafer is then dipped into an aqueous alkaline cleaning solution, and then cleaned between rotating rollers with a supply of water. The semiconductor wafer is then sprayed with water and dried.

  • Patent number: 8378040
    Abstract: A method for cleaning a distributor plate in a fluidized bed polymerization reactor system according to one embodiment includes, in a first mode, operating with about a normal, baseline value of superficial gas velocity in a fluidized bed polymerization reactor system having a reactor vessel, a recycle line, and a distributor plate in the reactor vessel near an inlet of the reactor vessel. In a second mode, the superficial gas velocity is increased above the baseline value of the first mode to a level sufficient to raise the temperature of the cycle gas at the inlet above an average temperature of the cycle gas at the inlet in the first mode, and to a level sufficient to dislodge foulant from holes in the distributor plate.

  • Patent number: 8372212
    Abstract: According to one embodiment, a supercritical drying method comprises cleaning a semiconductor substrate with a chemical solution, rinsing the semiconductor substrate with pure water after the cleaning, changing a liquid covering a surface of the semiconductor substrate from the pure water to alcohol by supplying the alcohol to the surface after the rinsing, guiding the semiconductor substrate having the surface wetted with the alcohol into a chamber, discharging oxygen from the chamber by supplying an inert gas into the chamber, putting the alcohol into a supercritical state by increasing temperature in the chamber to a critical temperature of the alcohol or higher after the discharge of the oxygen, and discharging the alcohol from the chamber by lowering pressure in the chamber and changing the alcohol from the supercritical state to a gaseous state. The chamber contains SUS. An inner wall face of the chamber is subjected to electrolytic polishing.

    Abstract: Apparatus and methods are provided for efficiently reclaiming solvents used to clean surfaces of semiconductor wafers, etc. More particularly, embodiments of the present invention provide an in-situ reclaim approach that utilizes condensing mechanisms to reclaim evaporated solvent components. In these embodiments, the condensing can occur within a proximity head itself and/or along a vacuum line running from the proximity head to a vacuum tank. Other embodiments of the present invention provide an in-situ reclaim approach that prevents the evaporation of solvents at the onset by maintaining appropriate equilibrium gas phase concentrations between the liquid chemistries and gases used to process wafer surfaces.
