| Research Abstract |
Traditional statistical process control are applied for processes where data are independent and identically distributed(i. i. d.). Therefore, this research presented statistical process control methods for autocorrelated processes such as semiconductor manufacturing process. Specifically, this research proposed the determination of the adjustment timing on the basis of the process capability, and control charts combining information about the state of statistical control and process capability were also developed for the judgment of adjustment timing. In addition to that, the process rate as control characteristics was presented, and factor assignment for supersaturated designs was proposed
