| Abstract | Temperature distributions in three dimensional (3D) ICs were analyzed with a thermal simulation and compared with measured results of test 3D ICs, in which sensor p-n diode arrays and on chip heaters were embedded. The 3D IC consists of a top tier test chip and a 410 um thick bottom dummy chip. Both top tier chips and bottom dummy chips were fabricated by a standard 0.18 um CMOS process. The top tier chips had four kinds of the thickness of 50 through 410 um. The temperature distributions of the top tier test chip under the constant heater power were analyzed by both measurements and thermal simulations. The thinner top tier structures showed the higher temperature and affected the temperature distributions. Effect of various boundary conditions such as substrate size and peripheral bonding pads were examined with thermal simulation. The test structure and the simulation modeling can provide an effective way for analysis of thermal conduction in 3D ICs. |

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.
