  • Publication number: 20160118242
    Abstract: Disclosed is a substrate processing method. The method includes: supplying a rinse liquid, IPA, a first fluorine-containing organic solvent, a second fluorine-containing organic solvent to a wafer within an outer chamber of a liquid processing unit; conveying the wafer to a supercritical processing unit container; and supplying a supercritical processing fluorine-containing organic solvent in a supercritical high-pressure fluid state to the wafer within the supercritical processing unit container. At least during the supply of the IPA, a low-humidity N2 gas is supplied into the outer chamber so that the inside of the outer chamber is formed as a low-humidity N2 gas atmosphere, and thus moisture absorption into the IPA is prevented.

  • Patent number: 8652344
    Abstract: A plurality of process liquid supply nozzles 10 are arranged at different levels on right and left sides of a semiconductor wafer W in a process bath 1. A discharge port of each of the nozzles 10 is directed toward the semiconductor wafer W. In accordance with a predetermined procedure, a process liquid is discharged from one or more nozzles 10 selected from the plurality of nozzles 10. In order to perform a chemical liquid treatment, a chemical liquid is discharged from the lowermost nozzle 10, for example, and thereafter, the nozzles 10 on the upper levels sequentially discharge the chemical liquid. In order to perform a rinse liquid treatment by replacing the chemical liquid in the process bath 1 with a rinse liquid, the rinse liquid is discharged from the lowermost nozzle 10 at first, for example. Thereafter, the rinse liquid is discharged from all the nozzles 10. In this manner, efficiency and uniformity in the liquid treatment can be improved.
