摘要： A plasma processing apparatus including: a monitor device which monitors a process quantity generated at plasma processing; a monitor value estimation unit which has monitor quantity variation models for storing change of a monitor value of the process quantity in accordance with the number of processed specimens and which estimates a monitor value for a process of a next specimen by referring to the monitor quantity variation models; and a control quantity calculation unit which stores a relation between a control quantity for controlling the process quantity of the vacuum processing device and a monitor value and which calculates the control quantity based on a deviation of the estimated monitor value from a target value to thereby control the process quantity for the process of the next specimen. Thus, a process model indicating variation of the state of a process processing apparatus can be added to a control loop in such run-to-run control that process conditions are changed according to each wafer process, so that stable processed results can be obtained even when variation occurs in processes.

摘要： Based on a model for determining optical emission intensity values Y at wavelengths from actuator values X of an etching apparatus, X is calculated from Y to achieve preferable Run-to-Run control over Y. A relation between X and Y is defined as a control model (matrix model C1, ratio-constraint model C2) based on an algebraical expression with ΔX as an input and ΔY as an output. In etching process control, ΔX (manipulated volume) is calculated from ΔY (controlled volume) using the control model, based on a non-control optical emission intensity value Y, to set X (S1) for the etching process, during which Y is monitored. Based on an actual value for Y, a non-control optical emission intensity value Y to be used in the next wafer etching process is calculated.
