Abstract
Pt diffused diodes (p(+) n n(+) junctions) were manufactured on 75 mu m n-t ype epitaxial Si wafers. Gettering of Pt by 3.1 MeV He-implantation induced defects was performed. The fleunce was 10(17) He/cm(2). A post thermal ann ealing at 1050 degrees C for 2 h gave rise to formation of a 0.2 mu m cavit y layer at the predicted projected range (R-p) as measured by XTEM (cross s ectional transmission electron microscopy). SIMS (secondary ion mass spectr oscopy) crater profiles of both B and Pt revealed that the cavities are eff icient sites to trap Pt atoms. (C) 2000 Elsevier Science S.A. All rights re served.
