Abstract:
PURPOSE: A substrate loading tool and a control method thereof, and a substrate processing apparatus and a storage media are provided to uniformly process a substrate by not including a lifter of a pin shape on the center part of a susceptor. CONSTITUTION: A first lifter is prepared in the inner side of a loading table which can project and supports external periphery portion of a substrate to be treated. A second lifter(8b1) supports the center part of the substrate to be treated instead of the location in which the first lifter supports the substrate to be treated. A circular arm(8d) circles from the upper side of the outside the loading table to the upper side of a loading surface of the loading table by the rotation of a shaft. A flexible arm(8g) is extended from the outer side of the first lifter to the inner side of the first lifter as a horizontal direction.
Abstract:
A substrate loading mechanism, a substrate transfer method, a substrate processing apparatus and a computer readable storage medium are provided to effectively suppress the deformation of the processed substrate by tightly supporting the processed substrate using a lift pin. The processed substrate having the flexibility is mounted on a main chuck(4). A plurality of lift pins support and lift the processed substrate. The substrate mount tool comprises drive machineries(9a,9b) for running the lift pin. A plurality of lift pins comprises the first lift pin(8a) and the second lift pin(8b). The drive machinery steadily supports the processed substrate in the state that the processed substrate bends below with the convex profile. A controller controls the drive of the first and the second lift pins by the drive machinery.

Abstract:
A substrate mounting unit is provided to restrain generation of process nonuniformity by controlling lifting of a substrate to be processed with respect to a mounting unit. A flexible substrate(G) to be processed is mounted on a mounting unit. A plurality of lifter pins(8a,8b) are prepared in a manner that appears and disappears with respect to a mounting surface of the mounting unit, supporting the substrate while moving up/down the substrate between a loading/unloading position of the substrate on the mounting unit and a mounting position on the mounting unit. A driving unit(9a,9b) drives the lifter pins. The plurality of lifter pins include a first lifter pin for supporting the main circumference of the substrate and a second lifter pin for supporting the center part of the substrate. When the substrate is elevated, the driving unit protrudes the first lifter pin higher than the second lifter pin so that the substrate is stably supported while the substrate is bent as a downward convex shape. The driving unit can independently drive the first and second lifter pins.
