| Abstract | For high density interconnection IC packages of the future, the outlook is for thinner packages with higher routing densities. With that, managing the substrate warpage along processing steps becomes critical. Thin organic substrates face challenging warpage issues in manufacture and in chip assembly. Glass is one of the candidates that can be used in substrate to replace traditional organic substrate. The infrastructure of glass for LCD industry has already been developed for many years. Glass also has several superior properties than other substrate candidates, such as large panel size availability, adjustable CTE, high modulus, low dielectric constant, low dielectric loss and high insulating capability. Glass represents an attractive choice with potential of tailorable properties dependent on specific glass composition. By targeting the coefficient of thermal expansion (CTE), the CTE of glass can be made to match perfectly with silicon dies and for reliable package. In addition, the advantages of using glass for interposer derive from process flexibility for size and thickness since the glass fusion process provides sheets with dimensions of more than three meters. It is straight forward to provide glass substrate of almost any size needed. Large glass panels are ideally suited for fabrication of interposer where the panel process is expected to provide large number of interposers in each run compared with wafer processing. In addition, the two sided processing of the panel, the avoidance of CMP processes and without using liners further enable lower unit cost for the interposer. This paper demonstrates fabrication of glass interposer with through glass vias (TGV) daisy chain test vehicles using a 20” x 20” (508mm x 508mm) panel size glass substrate manufactured by substrate HVM (high volume manufacture) line for 2.5D SiP application. Daisy chain electrical measurement results of this glass substrate demonstrated good continuity and electric resistance. The reliability test results will also be described including pre-condition and thermal cycle test (TCT). |

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.
