摘要
Silicon wafers were irradiated at tilted geometry to measure the lateral spread of tungsten ions in silicon for implantation energies between 40 and 360 keV. The depth profiles of implanted tungsten ions were measured by means of secondary ion mass spectrometry. The measured transverse range stragglings were obtained by using Furukawa and Matsumura's formula. An analysis of the measured transverse range stragglings as compared to the values calculated from the Biersack theory and SRIM reveals that the calculated transverse range stragglings from the Biersack theory correlated closer to the measured ones.
