  • Publication number: 20080006299
    Abstract: A cleaning processing apparatus comprises a spin chuck for holding a wafer W, an under plate being positioned to face the back surface of the wafer W with a prescribed gap provided therebetween, a support member for supporting the under plate, and a nozzle hole formed to extended through the plate member and the support member. A chemical liquid, a pure water and a gas can be supplied into a nozzle hole through opening-closing valves, and the chemical liquid and the pure water remaining inside the nozzle hole can be sucked by a sucking device. A pure water remaining inside the nozzle hole is sucked and removed by using the sucking device after the processing of the wafer W with a pure water and, then, a gas is spurted onto the back surface of the wafer W.

  • Patent number: 7300598
    Abstract: The invention relates to a process including a chemical liquid treatment and a rinse liquid treatment on a substrate, more particularly to a technique for reducing consumption of a chemical liquid while achieving uniform process and preventing particle generation. In a specific embodiment, the process is performed for removing a silicon oxide film formed on a silicon wafer. The process includes three subsequently performed steps, in which (1) diluted hydrofluoric acid (DHF), (2) DHF and de-ionized water (DIW), (3) DIW are supplied, respectively, onto a rotating wafer. Transition from step (1) to step (2) is done immediately before the hydrophilic silicon oxide film is dissolved to expose the underlying hydrophobic silicon layer.

  • Publication number: 20070223342
    Abstract: A substrate processing apparatus according to the present invention is provided with a spin chuck (3) that holds a substrate (W) and rotates the same. A process liquid supply system (11, . . . ) is disposed to supply a process liquid to the substrate rotated by the spin chuck. There are disposed a fluid nozzle (12) that supplies to the substrate a drying fluid having a higher volatility than that of the process liquid, and an inert gas nozzle (13) that supplies an inert gas to the substrate. A nozzle moving mechanism (15, 52, . . . ) is disposed that moves the nozzles (12, 13) radially outward relative to a rotational center (Po) of the substrate, while maintaining the inert gas nozzle nearer to the rotational center of the substrate than the fluid nozzle.

  • Publication number: 20070175501
    Abstract: In a substrate cleaning method and a substrate cleaning method according to the present invention, a brush 3 is brought into contact with a substrate W while rotating the same, and a cleaning position Sb of the brush 3 is moved relative to the substrate W from a center part of the substrate W toward a peripheral part thereof. A process fluid formed of liquid droplets and a gas is sprayed by a two-fluid nozzle 5 onto the substrate W, and a cleaning position Sn of the two-fluid nozzle 5 is moved relative to the substrate W from a center part of the substrate W toward a peripheral part thereof. During the movement of the cleaning position Sb of the brush 3 from the center part of the substrate W toward the peripheral part thereof, the cleaning position Sb of the two-fluid nozzle is positioned nearer to a center P0 than the cleaning position Sb of the brush 3. Since contaminations of the brush are prevented from adhering again to the wafer, it can be avoided that the wafer W is contaminated.

  • Publication number: 20070131256
    Abstract: After a rinse process on a wafer W is performed by feeding pure water to the surface of the wafer W at a predetermined flow rate while rotating the wafer W in an approximately horizontal state, a feed amount of the pure water to the wafer W is reduced, and a pure-water feed point is moved outward from the center of the wafer W. In this manner, the wafer W is subjected to a spin dry process while forming a liquid film in a substantially outer region of the pure-water feed point.

  • Publication number: 20070107751
    Abstract: Water vapor is mixed to O3 gas generated by an ozone generator of discharge type. The mixed fluid is cooled by a cooler, thereby impurities such as metals and nitrogen oxides contained in the O3 gas dissolve into condensed water. Subsequently, a gas-liquid separator separates the O3 gas from the condensed water. Water vapor is mixed with the O3 gas again. The mixed fluid passes through a metal trap composed of a container containing plural silicon chips as a metal adsorbent, thereby to remove the remaining metals therefrom.
