Abstract:
1. A processing system comprising: a processing chamber adapted for containing therein an object to be processed or a testing substrate for the object to be processed; a processing gas supply means adapted for supplying a processing gas into the processing chamber; a processing condition storage means adapted for storing therein processing conditions corresponding to details of a process, the processing conditions including a flow rate of the processing gas supplied from the processing gas supply means; an error information storage means adapted for storing therein error information about an error of a process result attributable to a difference between the object to be processed and the testing substrate; a model storage means adapted for storing therein a flow rate-process result-relationship model indicative of a relationship between the flow rate of the processing gas and the process result; a processing condition extracting means adapted for calculating a targeted process result of the testing substrate from a targeted process result of the object to be processed, based on the error information stored in the error information storage means, as well as adapted for extracting the processing conditions corresponding to the calculated targeted process result of the testing substrate, from the processing conditions stored in the processing condition storage means; a testing substrate processing means adapted for processing the testing substrate under the processing conditions extracted by the processing condition extracting means; a discriminating means adapted for discriminating whether or not the process result obtained by the process due to the testing substrate processing means is within a predetermined range relative to the targeted process result of the testing substrate; a flow rate calculating means adapted for calculating the flow rate of the processing gas, based on the process result obtained by the process provided to the testing substrate as well as on the flow rate-process result-relationship model stored in the model storage means, when the process result is judged not to be within the predetermined range by the discriminating means; and a flow rate changing means adapted for changing the flow rate of the processing gas of the processing conditions into the flow rate of the processing gas calculated by the flow rate calculating means when the flow rate of the processing gas is calculated by the flow rate calculating means, such that the testing substrate will be processed, at the changed gas flow rate, by the testing substrate processing means.
