The Mean Projected Range and Range Straggling of Er Ions Implanted in Silicon-On-Insulator
It is very important to consider the distribution of range, range straggling and lateral spread of ions implanted into semiconductor materials in design and fabrication of semiconductor integration devices by ion implantation. The mean projected ranges and range straggling for energetic 200 – 500 keV Er ions implanted in silicon-on-insulator (SOI) were measured by means of Rutherford backscattering followed by spectrum analysis. The measured values are compared with Monte Carlo code (SRIM2006) calculations. It has been found that the measured values of the mean projected range are good agreement with the SRIM calculated values; for the range straggling , the difference between the experiment data and the calculated results is much higher than that of .
