Evaluation of BBr2 + and B+ + Br + implants in silicon
Abstract
<p>The work carried out here examines the suitability of BBr<sub>2</sub> <sup>+</sup> and B<sup>+</sup> + Br<sup>+</sup> implants into crystalline (1 0 0) silicon for ultra-shallow junctions (USJ) applications. Rutherford backscattering spectroscopy (RBS) shows that an amorphous region is created during implantation of BBr<sub>2</sub> <sup>+</sup>, eliminating the need for a separate pre-amorphising implant. This amorphous region re-grows during subsequent rapid thermal annealing and there is evidence that bromine retards the re-growth velocity. Hall Effect measurements after rapid thermal annealing show a difference in electrical activation between the BBr<sub>2</sub> <sup>+</sup> and B<sup>+</sup> + Br<sup>+</sup> implants with the latter having the lower activation. Anomalous Hall mobility is also observed for the molecular implant at lower annealing temperatures.</p>
