Abstract:
A single-substrate-heat-processing apparatus for a semiconductor process, comprising:an airtight process chamber; a worktable configured to place a target substrate thereon and to heat the target substrate in the process chamber; a first heater configured to heat the worktable; a gas supply system configured to supply a process gas into the process chamber; an exhaust system configured to evacuate an interior of the process chamber; a moving mechanism configured to move the target substrate between a first position on the worktable and a second position above the worktable, the first and second positions being set to subject the target substrate to first and second processes, the first process having a process temperature higher than that of the second process; and a heat compensation member configured to surround the target substrate so as to compensate for heat dissipated from a peripheral portion of the target substrate when the target substrate is located at the second position, the heat compensation member being disposed in the process chamber and separated from an inner surface of the process chamber through a gap.
