In our previous study, using NF3 annealed poly-Si to improve gate oxide integrity for Co-silicide process has been proposed [SSDM, 1998, p. 164]. It is very interesting and important to know the mechanism of both F and N incorporation in the SiO2 and Co-salicide. In this study, F and/or N will be implanted into poly-Si with/without Co-salicide process, to identify the interaction of N and F in the SiO2 and Co-salicide process. In our work, we will describe the optimized structure and F/N incorporation for Co-silicide process. (C) 2002 Elsevier Science Ltd. All rights reserved.
Low contact resistance of poly-plug structure by in-situ HF-vapour cleaning

A low contact-resistance poly-plug structure realised by in-situ HF-vapour cleaning in a clustered tool is described. The native oxide in the contact area can be efficiently removed by the combination of an HF-dipping and in-situ HF-vapour cleaning process, resulting in a low specific contact resistance.
