  • Publication number: 20240042479
    Abstract: A substrate processing apparatus includes a rotational holding member that rotates a substrate around a predetermined rotational axis while holding the substrate, a liquid supply member that supplies a liquid to the substrate held by the rotational holding member, and a resin-made tubular guard that surrounds the substrate held by the rotational holding member. The tubular guard has an inner peripheral surface and an uneven portion disposed at the inner peripheral surface. The uneven portion has a plurality of recessed portions and a plurality of protruding portions placed between the recessed portions adjacent to each other. The recessed portion has a width smaller than a diameter of a liquid droplet scattering from the substrate held by the rotational holding member and a depth in which the liquid droplet does not come into contact with a bottom portion of the recessed portion in a state in which the liquid droplet is in contact with the protruding portions.

  • Patent number: 11810795
    Abstract: Disclosed is a substrate treating apparatus. All treating units are each arranged such that a treatment chamber, a chemical piping space, and an exhaust chamber are located side by side along a transportation space, the chemical piping space is located on a first side of the treatment chamber, and the exhaust chamber faces the chemical piping space across the treatment chamber when seen from the transportation space. The exhaust chamber faces the chemical piping space across the treatment chamber, leading to prevention of obstruction of a passage for passing a pipe, configured to supply a chemical to a substrate held by a holding rotator, by an exhaust pipe. Moreover, a single type of treating units is enough for the substrate treating apparatus instead of two types of treating units currently used. This results in sharing of components by all the treating units.
