Abstract :
The residual electrically active defects in implanted and annealed p-type Si (boron doped) have been studied with capacitance-voltage (CV) measurements and deep level transient spectroscopy (DLTS). P-type Si is implanted with 5.5 MeV Si ions to doses between 1012 and 10 14 cm-2. These samples were annealed at elevated temperatures (900°C). A critical dose is established indicating the transformation between point defects in to extended defects in contrast to n-type Si where a critical dose has been established for same species and under same annealing conditions below which no electrically active defects are seen
