| Abstract | A High speed IGBT utilizing an Electron Beam (EB) irradiation and a post annealing process for a carrier lifetime control for a thick n-drift layer has been developed for industry applications, and home appliance especially in the very small chip size to achieve a low cost and a minimizing a size requirements. Even under the extremely high current density of around a half order of higher than the conventional usage for long-time production life, stability of both a saturation voltage VCE(sat), on state forward voltage drop, and a turn off losses Eoff are needed from a reliability point of view. We investigated dependences on the carrier lifetime control processes and a conduction current stress condition by both the IGBT electrical characteristics stability, i.e. for ward out put I-V characteristics, switching characteristics, threshold voltage, and leakage current, and a physical analysis using the Cathode Luminescence (CL) method. And we confirmed that shifts of electrical characteristics are very slight without any problem to use in the relatively high current density operation. Only for the acceleration case, an obvious CL spectrum change can be observed and to be assigned each trap level. |

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.
