Quantitative Measurement of Arsenic Implant Dose by SIMS

Issues associated with making quantitative measurements of the arsenic implant dose in silicon by SIMS are described. These include the use of a certified reference material for calibration, the choice of silicon matrix reference species, the matrix normalization method, and minimization of detector count losses. A round-robin study is being conducted by ISO TC201/SC6 to determine the best analytical procedures and the level of interlaboratory agreement for this type of measurement.
