    摘要: During fault detection of a production process, the influence of the data communication process for communicating measurement readings to the fault detection system may be taken into consideration. In one illustrative embodiment, a data rate related parameter may be used as an input variable for a data reduction procedure, thereby enabling an efficient assessment of the quality of the remaining “real” process and tool parameters.

    摘要: By dividing a complex set of parameters of a production process in forming semiconductor devices into individual blocks, respective PCA models may be established for each block and may thereafter be combined by operating on summary statistics of each model block in order to evaluate the complete initial parameter set. Thus, compared to conventional strategies, a significant reduction of the size of the combined PCA model compared to a single PCA model may be obtained, while also achieving an enhanced degree of flexibility in evaluating various subsets of parameters.
