Abstract:
A test system for facilitating determining whether a plasma processing system (which includes a plasma processing chamber) is ready for processing wafers. The test system may include a computer-readable medium storing at least a test program. The test program may include code for receiving electric parameter values derived from signals detected by at least one sensor when no plasma is present in the plasma processing chamber. The test program may also include code for generating electric model parameter values using the electric parameter values and a mathematical model. The test program may also include code for comparing the electric model parameter values with baseline model parameter value information. The test program may also include code for determining readiness of the plasma processing system based on the comparison. The test system may also include circuit hardware for performing one or more tasks associated with the test program.
