摘要:
A method for calibrating a high frequency measuring device so as to accurately measure plasma processing parameters within a chamber. A calibration parameter is calculated from a first set of three reference loads measured by a high frequency measurement device. A second calibration parameter is calculated from S parameters measured between a connection point where the high-frequency measuring device is connected and the inside of the chamber of a plasma processing device. A second set of three reference loads, which include the impedance previously calculated and encompass a range narrower than that encompassed by the first set of three reference loads, is measured with the reference loads in the chamber. Another calibration parameter is calculated from the measured impedances of the second set of three reference loads measured by the high- frequency measuring device, and the true values of those impedances, and a detected voltage signal and a detected current signal are calibrated using the above calibration parameters.

A method is provided for calibrating a high-frequency, measuring device so as to accurately measure high-frequency parameters within a chamber. A calibration parameter is calculated from impedance of a first set of three reference loads measured by a high-frequency measuring device and the true values of those impedances. A calibration parameter is calculated from an S parameter measured between a connection point where the high-frequency measuring device is connected and the inside of the chamber of a plasma processing device. An impedance within the chamber is calculated from a voltage signal and a current signal calibrated using the above calibration parameters. A second set of three reference loads, which include the impedance calculated in Step 5 and encompass a range narrower than that encompassed by the first set of three reference loads, is determined. Another calibration parameter is calculated from impedances of the second set of three reference loads measured by the high-frequency measuring device and the true values of those impedances, and a detected voltage signal and a detected current signal are calibrated using the above calibration parameters.

An adaptive digital filter includes a filtering circuit and a coefficient renewal circuit. The filtering circuit has a coefficient a defined by a fundamental formula: a[n+1]=a[n]+β·e[n]·q[n]/p[n]. β is a number greater than 0 and smaller than 2, e[n] is a difference between the input and the output of the filter, and q[n] and p[n] are formulas. The renewal circuit calculates a renewal value of the coefficient a. The coefficient renewal circuit calculates 2m (m is an integer) greater than p[n] in the fundamental formula, and also calculates the renewal value of the coefficient a in accordance with an execution formula: a[n+1]=a[n]+β·e[n]·q[n]/2m in place of the fundamental formula.

A high-frequency measurement unit includes a signal detector for detecting a high-frequency signal, and a calibration coefficient storage for storing calibration coefficients Cmin and Cmax used to calibrate a value Amin detected at the lowest limit frequency fmin and a value Amax detected at the uppermost limit frequency fmax to a proper measurement value Asmin and to a proper measurement value Asmax, respectively. The high-frequency measurement unit further includes a frequency detection unit for detecting a frequency fm of the high-frequency signal, a calibration coefficient calculation unit for calculating a calibration coefficient Cm for the frequency fm, and a calibration unit for calibrating the value Am detected by the signal detector to a proper measurement value Asm by using the calibration coefficient Cm calculated by the calibration coefficient calculation unit.

摘要:
Configuration-wiring information is generated by a function-restricted netlist. A data-writing device writes the generated information to FPGAs. The restriction-lifting section lifts the restriction of the restricted configuration-wiring data. Then, a bit stream is generated based on the configuration-wiring data. The bit stream is encrypted in the encryption section and then decrypted in the decryption section. The decrypted data is written to the FPGA by the data writing section. A dongle stores permitted writing count information contracted with an IP vendor. A remaining writing count is calculated based on the writing count information every time the writing to the FPGA is performed. When the remaining writing count becomes zero, the functional restriction lifting and the decryption are prohibited, so that IP netlist cannot be written to the FPGA.
