| Abstract | The impact of inductance has rarely been considered in semiconductor Packaging. This is the reason for using the capacitor in the first place: it is a small, local energy reservoir for those current transients which cannot go back to the power supply without causing unacceptahly large voltage drops (V = L di/dt). Since 1978 a new chip carrier with integrated deeoupling capacitor (IDCCC) has been studied. T]he capacitor is located inside the bottom layer in a threelayer or a single-layer chip-carrier. The ceramic package previous!y used had a nonactive bonding pad layer: with our IDCCC, this layer (standard thickness is 25 mils) is made out of several layers from 3 to 5 mils with the electrodes. The technology is about the same as the one used in multilayer ceramic capacitors. This capacitor is located just under the device, but not under the conductor I/O to avoid a parasitic capacitive coupling. With the coming of leadless and leaded full array chip carriers such as pin grid array, we applied the same concept with a Capacitor inside the cap. The results with different current-pulse signals show the effects of the capacitor's inductance, resistance, and capacitance. The main specifications of this new chip carrier will be presented. In addition to improving speed and electrical Performances, the IDCCC allows an increase in density and in reliability 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.
