    Etch Rate Experiment (Myers & Montgomery, 2002)

    This case study explores the Myers and Montgomery (2002) etch rate experiment using response surface methodology (RSM) to optimise plasma etching in semiconductor manufacturing. A central composite design is used to model the effect of RF power and chamber pressure on etch rate.
