-20-200422243 (1) Description of the invention: [Technical field to which the invention belongs] The present invention relates to a substrate standby device that temporarily stands by a glass substrate and a substrate processing device including the same. [Prior Art] A substrate processing apparatus is used to perform various processes on glass substrates such as glass substrates for liquid crystal display devices, glass substrates for photomasks, glass substrates for optical disks, and the like. For example, in order to improve the production efficiency, a substrate processing apparatus is used which separates a series of processing units and combines a plurality of processing units. In this substrate processing apparatus, a substrate standby device (for example, see Japanese Patent Laid-Open No. 10-154652 and Japanese Patent Laid-open No. Hei 10-154652) is provided to temporarily wait for a glass substrate when transferring glass substrates between processing units. 9-199460). The glass substrate is supplied into the substrate processing apparatus by a substrate transfer apparatus. In this case, the substrate standby device in the substrate processing apparatus receives the glass substrate and temporarily waits for the substrate, and then transfers the glass substrate to a specific processing step. However, in recent years, glass substrates have been increasing in diameter, and the transfer arms (substrate support units) of substrate transfer devices that support glass substrates have also developed into various opening shapes. In this case, "If the substrate standby device is redesigned every time the shape of the transfer arm of the substrate transfer device is changed, it costs a lot. SUMMARY OF THE INVENTION The object of the present invention is to provide a substrate standby device and a substrate processing device including the same. The substrate standby device supports 90920.doc 200422243 units for a substrate having an arbitrary shape, and can transfer glass substrates. The substrate standby device of the present invention is a substrate standby device capable of advancing and retreating to a standby position in a state that supports a glass substrate, and a substrate standby device that transfers glass substrates at the standby position, and has the following mechanism: substrate standby The mechanism is set from the side of the forward and retreat route of the substrate conveying mechanism, and the direction intersects with the advance and retreat route. It can advance and retreat in the standby position and supports the bottom of the glass substrate. The substrate support mechanism is set to lower than standby The position can be moved up and down to a position higher than the standby position, and supports the underside of the glass substrate; and a control mechanism that controls the substrate standby mechanism and the substrate support mechanism so that the glass substrate between the substrate transfer mechanism and the substrate standby mechanism can be Handover and handover of the glass substrate between the substrate standby mechanism and the substrate support mechanism. In the substrate standby device of the present invention, the glass substrate is carried into or out of the substrate standby position by a substrate transfer mechanism. The substrate standby mechanism advances and retreats from the side of the substrate conveyance mechanism's advance and retreat path in a direction that intersects its advance and retreat path. This prevents contact between the substrate standby mechanism and the substrate transfer mechanism. As a result, the substrate standby device can transfer glass substrates to a substrate transfer mechanism having an arbitrary shape. In addition, the substrate supporting mechanism rises from a position lower than the substrate standby position to a position higher than the substrate standby position. Thereby, the glass substrate can be transferred between the substrate standby mechanism and the substrate support mechanism. The substrate support mechanism can also be configured to move up and down without touching the substrate standby mechanism while the substrate standby mechanism is advancing to the standby position. 0 90920.doc 200422243 In this case, even if the substrate support mechanism moves up and down, There is no contact with the substrate standby mechanism that advances to the standby position. Therefore, the glass substrate can be transferred between the substrate standby mechanism and the substrate support mechanism. The substrate stand-by mechanism may also include: a first member arranged on the side of the advancing and retreating route of the substrate conveying mechanism; and i or a plurality of second members that are arranged to be able to advance and retreat in a direction toward the standby position; and It is arranged on one or a plurality of second members, and supports the supporting part under the glass substrate. In this case, the support section supports the glass substrate, and one or more second members advance and retreat from the first member to the standby position. Therefore, the glass substrate can be transferred between the substrate standby mechanism and the substrate transfer mechanism. The support unit may also support the substrate transport mechanism to support the inside of the outermost fulcrum among the fulcrum of the glass substrate. In this case, the support portion supports the substrate transfer mechanism to support the inner side of the outermost fulcrum among the fulcrum of the glass substrate. Therefore, when the supporting portion supports the glass substrate, the bending of the glass substrate can be reduced. The substrate support mechanism may also include a plurality of abutment members that are movably arranged to be in contact with the lower surface of the glass substrate in the standby position, and a drive mechanism that allows the plurality of abutment members to move up and down. In this case, the plurality of abutment members are moved up and down by the driving mechanism. Therefore, the glass substrate can be transferred between the substrate supporting mechanism and the substrate standby mechanism. Furthermore, it is possible to have a conveying mechanism that is disposed at a position lower than the substrate standby mechanism and higher than the lowermost position of the substrate supporting mechanism, and conveys the glass substrate. In this case, the substrate supporting mechanism moves up and down from a position lower than the conveying mechanism to the substrate standby position. Therefore, by the substrate supporting mechanism moving up and down, the substrate supporting mechanism 90920.doc 200422243 and the transfer mechanism can transfer the glass substrate. A substrate processing apparatus for processing a glass substrate has the following mechanisms: a substrate transfer mechanism, which is set in a state that supports a glass substrate, 'can be advanced and retracted for a standby position; at least one pair of substrate standby mechanisms, which It is not placed on both sides of the forward and retreat route from the substrate transfer mechanism. It can be moved forward and backward for the standby position and supports the glass substrate. The substrate support mechanism is lower than the standby position. The position higher than the standby position is set to be movable up and down and supports the lower side of the glass substrate; and a control mechanism that controls the substrate standby mechanism and the substrate support mechanism to allow the transfer and transfer of the glass substrate between the substrate transfer mechanism and the substrate standby mechanism. Handover of glass substrate between substrate standby mechanism and substrate support mechanism. The transport mechanism may also include: a plurality of rollers extending in a direction intersecting the advancing and retreating directions; a roller supporting mechanism that can rotate to support the plurality of rollers; and a roller driving mechanism that rotationally drives the plurality of rollers. In this case, the substrate is transported in the advancing and retreating directions by a plurality of rollers that are rotationally driven by the roller driving mechanism. In the substrate processing apparatus of the present invention, the glass substrate is carried into or out of the substrate standby position by the substrate transfer mechanism. The substrate standby mechanism advances and retreats from the side of the forward and backward path of the substrate conveying mechanism in a direction that intersects its forward and backward path. This prevents contact between the substrate standby mechanism and the substrate transfer mechanism. As a result, the substrate processing apparatus can transfer glass substrates to a substrate transfer mechanism having an arbitrary shape. Also, the substrate supporting mechanism rises from a position lower than the substrate standby position to a position where it is high at 90920.doc 200422243 at the substrate standby position. Thereby, the glass substrate can be transferred between the substrate standby mechanism and the substrate support mechanism. Therefore, the substrate standby device can transfer glass substrates to a substrate transfer mechanism having an arbitrary shape.
