Book excerpt: High-energy ion implantation (above 200 keV) is now commonly used in a variety of VLSI processes. The high energy required for these implants is often achieved by implanting multiply charged ions, which inevitably brings in the problem of low-energy ion contamination. The low-energy contamination is difficult to diagnose and detect. Positron annihilation spectroscopy is used to examine the defect distributions in these high energy implants with varying degrees of contamination.

Abstract: Abstract of thesis entitled SOME POSITRON ANNIHILATION STUDIES ON HIGHLY DOPED AND SUPERSATURATED N-TYPE SILICON Submitted by HO KING FUNG for the degree of Doctor of Philosophy at The University of Hong Kong in July 2004 Positron Annihilation Spectroscopy (PAS) is a non-destructive technique that can be extensively used to probe the point defect structures found in solids. The basic physics behind PAS such as implantation, transport, vacancy trapping and annihilation are reviewed together with the various experimental techniques. Deconvolution algorithms have been applied to Coincidence Doppler Broadening Spectroscopy (CDBS) to improve the effective momentum resolution of the technique. The CDBS system instrumental resolution function is obtained using 85 the 514-keV line from Sr. The generalized least square method with Tikonov-Miller regularization, which incorporates a priori non-negativity constraints, is found to be very effective. Monte-Carlo simulations of CDBS have been used to optimize the deconvolution. The deconvolution technique, when applied to a series of well annealed polycrystalline metals, gives results that are found to be comparable quality-wise to those obtained by one dimensional Angular Correlation of Annihilation Radiation (ACAR). An attempt was made to evaluate the significance of ACAR data from positrons trapped in a crystal defect by defect studying the E-center (vacancy-dopant pair) in silicon. The Fourier transformation of the ACAR momentum distribution coming from positrons trapped at the E-center was studied. This gives in real-space the autocorrelation function of the positron-electron wavefunction product at the site of annihilation. Employing the ratio of the autocorrelation function for the E-center and bulk silicon, the positron binding energy to the E-center was estimated. It has been possible to approximately isolate that part of the E-centers' autocorrelation function that originates from the localized defect orbitals and to see spatial features relating to atomic positions in the E-center. Nonequilibrium processing consisting of ion implantation followed by annealing has been employed to produce supersaturated Antimony doped silicon. The defect structure of the ion implanted region and the post-implanted region have been studied using the Variable Energy Positron Annihilation Spectroscopy (VEPAS) technique. Evidence is given that positrons are trapped into precipitates or get trapped at precipitate boundaries at annealing temperatures less than 600C. Surprisingly, new vacancy defects appear in the implanted region at annealing temperatures over 600C. This is tentatively attributed to the fact that Sb precipitates begin to dissolve at these temperatures into VSb type complexes.

Book Synopsis Ion Implantation Technology - 92 by : D.F. Downey
Download or read book Ion Implantation Technology - 92 written by D.F. Downey and published by Elsevier. This book was released on 2012-12-02 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion implantation technology has made a major contribution to the dramatic advances in integrated circuit technology since the early 1970's. The ever-present need for accurate models in ion implanted species will become absolutely vital in the future due to shrinking feature sizes. Successful wide application of ion implantation, as well as exploitation of newly identified opportunities, will require the development of comprehensive implant models. The 141 papers (including 24 invited papers) in this volume address the most recent developments in this field. New structures and possible approaches are described. The implications for ion implantation technology as well as additional observations of needs and opportunities are discussed. The volume will be of value to all those who are interested in acquiring a more complete understanding of the current developments in ion implantation processes and comprehensive implant models.
