Abstract:
1. An apparatus for manufacturing a semiconductor wafer, comprising: a heat treatment chamber which is provided with a processing table on which a wafer substrate is placed, a transfer means having a surface which transfers the wafer substrate to the heat treatment chamber, a placing means which places the wafer substrate transferred by transfer means onto the processing table, a front surface-side heating means which heats a front surface of the wafer substrate, a back surface-side heating means which heats a back surface of the wafer substrate, an automated control means which controls the transfer means to transfer the wafer substrate to a location suspended on the surface above the processing table in the heat treatment chamber and to suspend the wafer substrate on the surface above the processing table for a predetermined time period until the wafer substrate is warped, and a placing control means which controls the placing means to place the warped wafer substrate onto the processing table by the placing means, the wafer substrate being warped from being suspended above the processing table by the transfer means for the predetermined time period.
