Abstract | Heretofore, the schemes for fabricating a complementary transistor structure in a monolithic functional block entailed either some additional, difficult-to-control processing steps or a sacrifice in isolation of the collector regions of one type of transistor. This paper describes an isolated p-n-p transistor structure fabricated by the same technique used for the conventional all n-p-n transistor functional block without any additional processing steps. The basic p-n-p transistor has a lateral structure. During the p-type base diffusion of the n-p-n transistor, two concentric p-type regions at close distance are selectively diffused into an isolated n- type region such as that used for the collector of an n-p-n transistor. The center p-type diffused region forms the emitter and the outer ring forms the collector. The n-type spacing between these two regions serves as the base. The current gain of this transistor is not high, typically around unity. However, by amplifying the collector current of the p-n-p transistor with an n-p-n transistor, the composite transistor acts like a high gain p-n-p transistor and the composite current gain can be made comparable to that of the n-p-n transistor in the same functional block. The lateral complementary transistor has been used extensively and successfully for the fabrication of linear functional blocks such as those used in the Advanced Minuteman Program. |

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.
