Abstract

The formation of extended defects resulting from the precipitation of the large amounts of interstitials and vacancies generated during the dopant and pre-amorphisation implantation is the major issue related to the formation of highly doped p+/n junctions. Interactions between defects and implanted dopants produce diffusion and activation anomalies that are among the major obstacles to the realisation of ultra-shallow junctions satisfying the ITRS requirements. The ideal thermal treatment should remove all the damage and get a high dopant activation with minimal diffusion. Modifying first the depth of the end-of-range damage by varying the pre-amorphisation implantation energy and the thermal budget by using second (spike) and millisecond (fRTP) annealing, the optimal values for implantation energy and thermal budget can be extracted for a complete defect annihilation. Transmission electron microscopy is used to determine the crystal quality. copyright The Electrochemical Society.
