A gas supply system for supplying a gas into a processing chamber for processing a substrate to be processed includes: a processing gas supply unit; a processing gas supply line; a first and a second branch line; a branch flow control unit; an additional gas supply unit; an additional gas supply line; and a control unit. The control unit performs, before processing the substrate to be processed, a processing gas supply control and an additional gas supply control by using the processing gas supply unit and the additional gas supply unit, respectively, wherein the additional gas supply control includes a control that supplies the additional gas at an initial flow rate greater than a set flow rate and then at the set flow rate after a lapse of a period of time.

Gas supply system, substrate processing apparatus and gas supply method

A substrate processing apparatus includes a substrate processing unit for performing a process on substrates; a recipe protection unit for prohibiting processing conditions for the process from being changed while the process is being performed on a specific number of substrates; a protection cancellation unit for canceling a prohibition of a change in the process to allow the processing conditions to be changed while the process is being performed on the specific number of substrates; and a modifying unit for modifying the processing conditions. Further, a method for examining substrate processing conditions includes a protection cancellation step of canceling a prohibition of a change in the process to allow the processing conditions to be changed while the process is being performed on the specific number of substrates; and a modifying step of modifying the processing conditions.

Substrate processing apparatus, method for examining substrate processing conditions, and storage medium

The present invention provides a substrate processing apparatus that executes electrical discharge processing before detaching a substrate held onto an electrostatic chuck of a lower electrode constituting a stage and undergoing a specific type of processing from the electrostatic chuck. Before electrically discharging the substrate, a decision is made as to whether or not the specific type of processing on the substrate has ended normally, and electrical discharge conditions are set based upon regular electrical discharge condition information stored at a regular electrical discharge condition information storage means if the substrate processing is judged to have ended normally, whereas electrical discharge conditions are set based upon non-regular electrical discharge condition information stored at a non-regular electrical discharge condition information storage means if the substrate processing is judged not to have ended normally. Then, under the electrical discharge conditions having been set, electrical discharge processing is executed on the substrate.
