Definitions
- the present invention relates to a substrate processing system and a semiconductor device manufacturing method.
- the present invention relates to a substrate processing system and a method for manufacturing a semiconductor device.
- a film forming process for forming a gate insulating film and a gate electrode film on a wafer surface is performed.
- the deposition process for the gut insulating film and the gut electrode film is usually performed under a reduced pressure environment by supplying raw materials to the wafer in gaseous or plasma state and depositing a thin film on the wafer surface by a chemical catalytic reaction on the wafer surface. It is used in equipment and film forming equipment such as sputtering equipment that sputters the film material by ion bombardment and physically deposits a thin film on the wafer surface.
- a wafer cleaning process for removing impurities such as organic substances and metals attached to the wafer is performed. This is because if impurities are attached to the wafer, film formation is hindered by the impurities and a desired film is not formed on the wafer.
- This cleaning process is performed by supplying a cleaning liquid to the wafer in a cleaning device provided independently of the film forming device.
- the cleaning apparatus for example, after the wafer is cleaned with a cleaning liquid, the wafer is spun dry by rotating the wafer at a high speed (for example, Japanese Patent Laid-Open Publication No. 2002-202). 1 9 4 2 4).
- the conventional wafer is cleaned using a cleaning liquid in the above-described cleaning apparatus, shaken off and dried, and then transferred to the above-described film forming apparatus to form a film.
- the present invention has been made in view of such a point, and completely removes moisture adhering to a substrate such as a wafer by washing, and removes the moisture from the substrate to another film forming apparatus such as a film forming apparatus. It is an object of the present invention to provide a substrate processing system that can be transported to a processing apparatus and a method of manufacturing a semiconductor device.
- the substrate processing system of the present invention uses a cleaning liquid.
- a cleaning device for cleaning the substrate, a moisture removing device for removing moisture attached to the substrate cleaned by the cleaning device, and a substrate for which the moisture has been removed by the moisture removing device is passed through a dry atmosphere for other processing of the substrate.
- a transport unit for transporting to the device.
- cleaning apparatus can be dried by the exclusive moisture removal apparatus, and the said dried board
- the cleaning device may be connected to the moisture removing device, the moisture removing device may be connected to the transport unit, and the transport unit may be connected to the other processing device. In such a case, the continuous transfer of the substrate from the cleaning device to the moisture removal device, the transfer section, and other processing devices is smoothly performed.
- the transfer unit may be connected to a loading / unloading unit for loading / unloading the substrate from / to the substrate processing system.
- the moisture removing device may include a heating member for heating the substrate. In such a case, by heating the substrate, water adhering to the substrate and remaining water can be more reliably removed.
- the heating member may heat the substrate by radiation. In this case, since heat can be supplied to the substrate from a distant position, the substrate surface is evenly heated without unevenness, and all the moisture in the substrate surface can be removed.
- the moisture removing device may include a rotation mechanism for rotating the substrate.
- this rotating mechanism for example, the substrate to which the high-temperature gas is supplied can be rotated to dry the substrate more evenly.
- the moisture removing device may include a high-temperature gas supply unit that supplies a high-temperature gas to the substrate.
- the high-temperature gas is a gas at least at a temperature higher than room temperature.
- the high-temperature gas preferably has an oxygen content of 4 ppm or less.
- the moisture removing device provided with the high-temperature gas supply section may have a rotating mechanism for rotating the substrate.
- the moisture removing device may include a moisture concentration measuring member for measuring the moisture concentration in the moisture removing device.
- a moisture concentration measuring member for measuring the moisture concentration in the moisture removing device.
- the moisture removing device may include an exhaust portion for exhausting the inside of the moisture removing device, and the moisture concentration measuring member may be provided in the exhaust portion.
- a shirt for opening and closing a transfer port of the substrate between the water removing device and the transfer unit, and a measurement result of the water concentration from the water concentration measurement unit are output.
- a control unit that controls opening and closing of the shutter based on the measurement result the shirt can be opened only when, for example, the moisture concentration in the moisture removing device falls below a predetermined threshold. Therefore, the substrate does not pass through the moisture removing device before the moisture is sufficiently removed from the substrate, and the substrate with the remaining moisture can be prevented from being processed by another processing device.
- the moisture removing device may include a decompression device for reducing the pressure inside the moisture removing device.
- a decompression device for example, the pressure of the water removal device ⁇ can be reduced between the pressure in the cleaning device and the pressure in the transfer unit. Therefore, when the substrate is transferred to the cleaning device, the water removal device, and the transfer section in this order, the pressure is gradually reduced, and the load on the substrate due to the pressure fluctuation can be reduced.
- the moisture removing device may be provided with a gas supply unit for supplying a gas other than oxygen gas to the entire inside of the moisture removing device.
- the gas supply unit can maintain the inside of the moisture removing device in a low oxygen atmosphere, thereby preventing, for example, oxidation of the substrate in the moisture removing device and deterioration of the film on the substrate.
- the transfer unit may include a casing that covers a transfer passage of the substrate, and the casing may include a dry gas supply unit that supplies a dry gas into the transfer passage. Supplying dry gas from this dry gas supply unit This keeps the casing in a dry atmosphere and prevents moisture from adhering to the substrate being transported.
- the dry gas may be a gas other than oxygen gas.
- the transfer section may be provided with a pressure reducing mechanism for reducing the atmosphere in the transfer passage.
- the pressure reducing mechanism may include a control unit that can control the pressure in the transfer passage to be between the pressure in the other processing device and the pressure in the moisture removing device. That is, when the pressure in the transfer passage and P alpha, 2 [rho the pressure in the other processing unit, the pressure in the water removal apparatus and [rho 3, pressure reducing mechanism will [rho 2 rather P i rather [rho 3 May be provided. In such a case, for example, even if the processing in another processing unit is performed at a high degree of pressure reduction, the degree of pressure reduction can be increased in the order of the water removal unit, the transfer unit, and the other processing unit. The substrate can be prevented from being damaged.
- the other processing apparatus may be a film forming apparatus for forming a film on a substrate.
- the substrate from which moisture has been removed is carried into the film forming apparatus, so that the film forming process can be performed properly.
- the substrate processing system provided with the film forming apparatus may further include a film thickness measuring member for measuring the film thickness of the film formed on the substrate in the film forming apparatus. With this film thickness measuring member, the film thickness of the film formed on the substrate can be inspected at an early stage. Therefore, if when the film is not properly formed, the substrate can be corrected the defect stopped immediately deposition apparatus prior to being manufactured on a large amount (Note that the other processing apparatus, etching It may be a device.
- the cleaning device may be provided with an air supply unit that is covered with a housing and supplies gas other than oxygen gas into the housing. If moisture adheres to the substrate in the cleaning device, the moisture makes it easier for oxygen in the surrounding atmosphere to react with the substrate.
- the cleaning device is provided with an air supply section and supplies a gas other than oxygen into the housing to reduce the inside of the housing to a low oxygen atmosphere. It can maintain and suppress the reaction between oxygen and the substrate. Therefore, for example, it is possible to prevent the film on the substrate from being oxidized and being deteriorated.
