Abstract
Airborne boron and phosphorus contaminations on wafer surface has been analysed by TOF-SIMS. A known boron and phosphorus concentration BPSG sample was used as reference for the calibration of the TOF-SIMS. The detection limit reaches 1E8 at/cm2 for boron and 1E10 at/cm2 for phosphorus. This method is easy to applied and no sample preparation required. So TOF- SIMS is a very good monitoring technique for airborne boron and phosphorus on wafer surface.
