  • Publication number: 20140360041
    Abstract: A substrate treating apparatus includes a fluid supply unit to supply a fluid to a chamber. The substrate is dried in the chamber using the fluid in a supercritical state. The fluid supply unit includes a storing tank to store the fluid and a conversion tank connected to the storing tank through a connection tube and to the chamber through a supply tube. The conversion tank includes a heater to heat the fluid.

  • Publication number: 20140291421
    Abstract: Provided is a substrate treating apparatus including a housing; a plurality of opening-and-closing members configured to provide a driving force for opening and closing the housing; a fluid storing member supplying a fluid to the opening-and-closing members; and a fluid distribution unit connected to the fluid storing member via a supply conduit to distribute the fluid supplied from the fluid storing member to the opening-and-closing members. The fluid distribution unit includes a distribution conduit diverging from the supply conduit and connected to a corresponding one of the opening-and-closing members; and a fluid distribution member provided at a junction between the supply conduit and the distribution conduit.

  • Publication number: 20140283886
    Abstract: In a supercritical fluid method a supercritical fluid is supplied into a process chamber. The supercritical fluid is discharged from the process chamber as a supercritical fluid process proceeds. A concentration of a target material included in the supercritical fluid discharged from the process chamber is detected during the supercritical fluid process. An end point of the supercritical fluid process may be determined based on a detected concentration of the target material.

  • Publication number: 20140262024
    Abstract: Substrate treatment systems are provided. The substrate treatment systems may include a treating device configured to treat a substrate with a supercritical fluid, and a supplying device configured to supply the supercritical fluid to the treating device. The treating device may include a supercritical process zone in which the substrate is treated with the supercritical fluid, and a pre-supercritical process zone in which the supercritical fluid is expanded and then provided into the supercritical process zone to create a supercritical state in the supercritical process zone.

  • Publication number: 20120064727
    Abstract: Substrate treatment equipment includes a wet treatment apparatus for treating a substrate with a solution (liquid), a drying (treatment) apparatus discrete from the wet treatment apparatus and for drying the substrate using a supercritical fluid, and a transfer device. The substrate is extracted by the transfer device from the wet treatment apparatus after the substrate has been treated and the substrate is transferred by the device while wet to the dry treatment apparatus. To this end, various elements/methods may be used to keep the substrate wet or wet the substrate. In any case, the substrate is prevented from drying naturally, i.e., from air-drying, as the substrate is being transferred from the wet treatment apparatus to the drying apparatus. Thus, equipment and method prevent defects such as water spots and the leaning of fine structures on the substrate.
