| Abstract | Copper wire is now becoming popular that emerge to replace the widely used gold (Au) wire in a semiconductor industry as way of interconnecting the chip to the package. It was well proven that Copper (Cu) wire is better in terms of electrical performance which also maintains same quality & reliability level and most importantly lower in cost. Wirebonding is one of the most critical and complex processes in the whole assembly packaging flow. Demanding market applications can no longer be meet in a single die device packaging alone so a multiple chip packaging either in a “side by side” or multiple “stacked die” configurations are needed. At this condition conventional wirebonding process through “forward bonding” interconnection method cannot simply satisfy but rather opt through SSB (stand-off stitch bond) bonding application which is also known as reverse bonding. This paper will demonstrate the results of the Cu wirebonding process development in a dual die package having interbond connection between die with a challenge faced primarily focus in controlling the inherent “bump” oxidation of Cu wire material. |

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.
