20080248597 | Methods for determining a dose of an impurity implanted in a semiconductor substrate and an apparatus for same - Methods of determining a total impurity dose for a plasma doping process, and an apparatus configured to determine same. A total ion dose implanted in a semiconductor substrate is directly measured, such as by utilizing a Faraday cup. A ratio of impurity-based ion species to non-impurity-based ion species in a plasma generated by the plasma doping process and a ratio of each impurity-based ion species to a total impurity-based ion species in the plasma are directly measured. The ratios may be directly measured by ion mass spectroscopy. The total ion dose and the ratios are used to determine the total impurity dose. The apparatus includes an ion detector, an ion mass spectrometer, a dosimeter, and software. | 10-09-2008 |
