| Abstract | Summary form only given, as follows. The gettering of some common impurities such as Fe, Cu, Al and Na in silicon wafers from low energy and high dose hydrogen ion implantation was studied. It is found that PIII is an effective and economic technique to integrate the gettering and doping processes and a very clean layer in the silicon wafers could be formed. Because hydrogen ions dominate in the hydride dopant plasma and H/sub 2/ is usually used in PIII doping experiments as a dilution gas, low energy and high dose H-implantation introduces more effective gettering of the common impurities in Si. Si wafers were first implanted using plasma immersion ion implantation (PIII) technique. Hydrogen and the damaged layers were then annealed to drive the hydrogen out to leave a band of cavities close to the original project range. The profiles of the common impurities as well as implanted hydrogen were evaluated using secondary ion mass spectrometry. To optimize the implantation and annealing conditions for the most effective gettering, suitable processing conditions were determined after investigating the influence on the gettering effect of changing implantation energy, dose, annealing temperature and annealing time, respectively. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
