Popis: We applied statistical experimental design concepts to the study of the interaction of ion implantation with remote‐plasma photoresist ashing. A 28–4IV fractional‐factorial screening experiment revealed that implant species and resist hard bake conditions were not significant factors for resist ash rate and uniformity. We obtained quadratic polynomial response surface models using a G‐optimal experimental design as a function of the remaining four ash variables (temperature, pressure, oxygen, and hydrogen mass flow rates) and two implant factors (implant dose and energy). Ion implant dose had a significant effect on ash rate while implant energy was an important factor for ash rate uniformity.
