Abstract:
A leakage determining method determines whether or not atmospheric air enters a vacuum transfer chamber for transferring a substrate under a vacuum atmosphere between a preliminary vacuum chamber and a processing chamber. The method includes controlling a pressure in the vacuum transfer chamber to a preset pressure by supplying a pressure control gas into the vacuum transfer chamber; performing supply control, when the substrate is not transferred, by reducing the amount of the pressure control gas supplied into the vacuum transfer chamber or stopping the supply of the pressure control gas; and measuring an oxygen concentration in the vacuum transfer chamber after the supply control of the pressure control gas and determining leakage of atmospheric air into the vacuum transfer chamber by determining whether or not atmospheric air whose amount exceeds a preset allowable level enters the vacuum transfer chamber based on temporal changes of the measured oxygen concentration.
Abstract:
Provided is an apparatus that transfers a substrate inside a substrate transfer chamber by a substrate transfer module using magnetic levitation. The apparatus includes: a substrate transfer chamber having a floor portion provided with a first magnet and connected, through an opening portion, to a substrate processing chamber in which the substrate is processed; and a substrate transfer module including a substrate holder configured to hold the substrate, and a second magnet configured such that a repulsive force acts between the first magnet and the second magnet. The substrate transfer module is movable inside the substrate transfer chamber by the magnetic levitation based on the repulsive force. The substrate transfer module performs loading/unloading of the substrate by directly entering into the substrate transfer chamber via the opening portion, or delivers the substrate to and from a substrate transfer mechanism fixedly provided inside the substrate transfer chamber.
Abstract:
In a vacuum processing device, a loading/unloading port, a normal pressure transfer chamber and a vacuum transfer chamber are arranged in that order from a front side toward a rear side, and load-lock chambers are connected to the normal pressure transfer chamber. The position in the front-rear direction in a movement range of a wafer W in the normal pressure transfer chamber overlaps with the positions in the front-rear direction of the load-lock chambers. Three vacuum processing modules are connected to each of the left and right sides of the vacuum transfer chamber. Vacuum processing units are arranged in each of the vacuum processing modules in a front-rear direction when viewed from the vacuum transfer chamber side. Wafer mounting shelves for holding wafers W in the load-lock chambers are arranged in the front-rear direction when viewed from the vacuum transfer chamber side.

Abstract:
A substrate cooling method is for, using a load-lock mechanism for controlling a pressure therein between a first pressure close to an atmospheric pressure and a second pressure in a vacuum state, cooling a substrate transferred from the second module to the first module. The method includes maintaining a pressure in the chamber to the second pressure, allowing the chamber to communicate with a second module, and loading the substrate into the chamber; locating the substrate to a cooling position close to the cooling member; exhausting the chamber such that the pressure in the chamber becomes a third pressure where a region between a surface of the cooling member and a backside of the substrate satisfies a molecular flow condition. The method further includes introducing a purge gas into the chamber to increase the pressure in the chamber to the first pressure, and cooling the substrate by the cooling member.

Abstract:
A method includes a first step of vertically moving the arm or the pins from a reference position in one direction by a predetermined distance, a second step of moving the arm in a horizontal direction, a third step of vertically moving the arm or the pins moved in the one direction in the other direction by a distance equal to or greater than the predetermined distance, a fourth step of detecting a horizontal position of the substrate held by the arm with respect to the arm. The steps are repeated. Whenever the processes are performed, the reference position in the first step is shifted in the one direction by the predetermined distance, and a vertical position of the arm or the pins which is obtained when the horizontal position of the substrate detected in the fourth step is deviated from a preset position is taught as the delivery position.
