| Abstract | A whole benzocyclobutene (BCB) membrane zero-level packaging using a wafer level bonding technique is presented. Wafer-scale membrane transfer technique using silicon carrier wafers was used to make BCB membrane caps placed above the device wafers. BCB multiple coating process using CYCLOTENE 4026-46 was developed for an encapsulation cap. The average height of the implemented BCB cap was approximately 40 mum with a little curvature for the dimension of 2 mm x 3 mm. Hermeticity of BCB was improved by depositing 0.5 um-thick PECVD nitride on the membrane, which was verified by vacuum chamber test and the ANSYS model was developed to describe the BCB membrane movement depending on the vacuum level. Mechanical resonant frequency of the BCB membrane was also characterized 7.5 kHz with an optical measurement. In addition, RF characterization using coplanar waveguide (CPW) line and thin-film resonator were performed to estimate the effect of BCB film package from DC to 110 GHz. The packaged thin-film resonator showed a frequency change of 100 MHz at 62.5 GHz resonance frequency and 200 MHz at 104 GHz. |

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.
