Read the Ion implantation class notes.
Antimony is implanted into a silicon wafer that has a background doping of 6x1014 cm–3.
The implant energy is 600 keV. (See the notes for range and straggle plots.)
There is no anneal following the implant.
Determine the dose needed to so that the implanted profile has a peak concentration of NP = 7x1017 cm–3.
Then calculate the corresponding junction depth(s).
