A controller disclosed herein drives, in a first step, a high frequency generating source at a first energy condition, and drives, in a second step, a high frequency generating source at a second energy condition. Prior to a switching time of the first step and the second step, the controller switches gas species supplied from the gas supply system into the processing container, and sets a gas flow rate in an initial period just after the switching to be larger than a gas flow rate in a stabilization period after lapse of the initial period.

Plasma processing apparatus and plasma processing method

A temperature control method is provided for controlling a plasma processing apparatus that is capable of changing a temperature setting for each step of a plasma process including multiple steps. The method includes a transfer step of performing an entry process for transferring a workpiece into a processing chamber of the plasma processing apparatus and/or an exit process for transferring the workpiece out of the processing chamber, a process execution step of executing the plasma process including multiple steps, and a temperature control step of performing a first temperature control and/or a second temperature control. The first temperature control includes controlling a temperature to a temperature setting of a next process according to a time execution of the plasma process is completed, and the second temperature control includes controlling the temperature to the temperature setting of the next process in parallel with the entry process and/or the exit process.

Temperature control method, control apparatus, and plasma processing apparatus

Provided is a parallel flat-panel type plasma processing apparatus which includes a recipe storing unit storing a processing recipe for performing a plasma processing, a compensation setting unit setting an accumulation time of the plasma processing or the number of processed substrates after starting using a new second electrode and the compensation value of the set temperature of the second electrode in an input screen, and a storage unit storing the compensated set value. The plasma processing apparatus is further equipped with a program for controlling a temperature adjusting mechanism based on a set temperature after compensation by adding a set temperature of an upper electrode written in the processing recipe to the compensation value stored within the storage unit. As a result, the non-uniformity in the plasma processing between the substrates caused by the change of processing atmosphere is suppressed.
