A substrate processing apparatus delivers a gas between a lower surface of a substrate and a base surface of a base part to form an airflow flowing radially outward and to cause a pressure drop in a space between the substrate and the base part by the Bernoulli effect. The base surface includes a second surface sloping upward in a radially outward direction. A third surface slopes downward in a radially outward direction from the outer peripheral edge of the second surface. A fourth surface is an annular surface contiguous to the lower edge of the third surface. The fourth surface expands radially outward outside the outer peripheral edge of the substrate in the radial direction. Accordingly, it is possible to suppress adhesion of a processing liquid to the lower surface of the substrate and to improve the stability of holding the substrate.

Substrate processing apparatus

Disclosed is a substrate treating apparatus for treating a substrate with a treating liquid, the apparatus including the following: a rotating member including a plurality of through-holes formed therein; a plurality of support pins attached to the through-holes with a non-sealing structure, and configured to support a substrate in such a manner that the substrate is spaced apart; a supply nozzle configured to supply a treating liquid to the substrate; a cover spaced apart below the rotating member; a rotational drive device configured to drive the rotating member rotationally in a horizontal plane; and a drive device configured to drive the support pins.

Substrate treating apparatus

A substrate treating apparatus includes a carrier platform, a transport mechanism, and a controller. The carrier platform places a carrier thereon. The carrier includes a plurality of shelves arranged in an up-down direction. The shelves are each configured to place one substrate thereon in a horizontal posture. The transport mechanism is configured to transport a substrate to a carrier placed on the carrier platform. The controller controls the transport mechanism. The transport mechanism includes a hand and a hand driving unit. The hand supports a substrate. The hand driving unit moves the hand. The controller changes a height position of the hand when the hand is inserted between two of the shelves adjacent to each other in the up-down direction, depending on a shape of a substrate taken from or placed on one of the shelves by the transport mechanism.

Disclosed are a substrate treating apparatus and a substrate transporting method. The substrate treating apparatus includes a first transport mechanism. The first transport mechanism includes a hand. A hand includes a base, a suction portion, a first receiver, a second receiver, and a receiver driving unit. The suction portion is attached to the base. The suction portion flows gas along a top face of a substrate, and sucks the substrate upward without contacting the substrate. The first receiver and the second receiver are supported on the base. The first receiver and the second receiver are disposed below the substrate sucked by the suction portion. The first receiver and the second receiver can receive a back face of the substrate. The receiver driving unit moves the second receiver with respect to the base. The receiver driving unit causes the second receiver to access the first receiver and to move away from the first receiver.

Substrate treating apparatus and substrate transporting method

A treatment device treats a treatment subject inside a treatment chamber with treatment fluids of a plurality of types. An exhaust switching unit is provided to an exhaust pipe connected to the inside of the treatment chamber, and the exhaust switching unit is formed of a distribution box, switching valve boxes, and an exhaust tube. Additionally, the switching valve boxes, which correspond in number to the treatment fluids, are connected to the distribution box in a parallel state.

Treatment device and exhaust switching device therefor, and exhaust switching unit and switching valve box

A substrate processing apparatus includes a washing liquid supply unit which supplies a washing liquid to a washing liquid discharge port which is open in the outer circumferential surface of a body, a rotation unit which relatively rotates the opposing member and the body around a rotational axis passing through the central portion of the upper surface of the substrate and a washing control unit which controls the washing liquid supply unit and the rotation unit so as to wash the cylindrical gap, where the washing control unit performs a rotation step of controlling the rotation unit so as to relatively rotate the opposing member and the body and a washing liquid discharging step of controlling the washing liquid supply unit so as to discharge a washing liquid from the washing liquid discharge port simultaneously with the rotation step.
