Abstract | A new D2W collective bonding approach is demonstrated with functional MEMS devices with smaller than 3 × 3 $mm^{2}$ and 8 inch ASIC wafers. The new package design was proposed in order to reduce the parasitic effect by attaching the released MEMS dice directly to the pads on an ASIC wafer. Two different types of MEMS devices having combs structure and a beam structure were used in order to confirm the minimal change in the MEMS functionality before and after D2W bonding. The ASIC wafer consisted of non functional circuit with pads and the daisy chain for measuring the electrical resistance and interconnection lead-out. With the new method by utilizing both the standard pick and place machine and the wafer bonder, ~ 800 numbers of functional MEMS dice were bonded to ASIC by low temperature D2W collective bonding at 200 degC for 2 minutes having an alignment tolerance less than 10% in 150 μm pitch with pad size of 75 μm. In this approach, the bonding time has been reduced by more than 50% in comparison with the conventional D2W bonding with flip chip bonder and performance of the package was improved by direct interconnection and the yield was improved by bonding with Known Good Dice. |

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.
