Abstract:
A method for manufacturing a semiconductor device, comprising:setting a wafer supporter at a standby position in a processing chamber, and maintaining the wafer supporter at the standby position to equilibrate a temperature of the wafer supporter and a temperature prevailing in the processing chamber at the standby position, without any wafer being loaded on the wafer supporter, wherein the temperature in the processing chamber is stabilized at a standby temperature;using an elevator to lower the wafer supporter from the standby position to a wafer load/unload position once the temperature in the processing chamber has stabilized;loading a wafer onto the wafer supporter once the wafer supporter is at the load/unload position;subsequently using the elevator to elevate the wafer supporter with the wafer loaded thereon from the load/unload position to a process position located above the standby position in the processing chamber;performing a process for manufacturing a semiconductor device while the wafer supporter is at the process position with the wafer loaded thereon;using the elevator to re-lower the wafer supporter with the wafer loaded thereon to the wafer load/unload position after completing the manufacturing process;unloading the processed wafer from the wafer supporter; andsubsequently using the elevator to re-elevate the wafer supporter to the wafer standby position without any wafer being loaded thereon.
