Abstract | The development of integrated sensor technology during the past decade, which has made possible the fabrication of a wide variety of microstructures on a high-volume basis, is discussed. Bulk micromachining is widely practiced using double-sided processes, while the single-sided dissolved-wafer bulk process offers advantages for many applications. Surface micromachining avoids the necessity of deep etching of the wafer bulk but requires careful control of stress in the deposited films and protection of the wafer during the sacrificial etch. Wafer-scale bonding processes such as electrostatic bonding and silicon fusion offer additional tools for the creation of three-dimensional microstructures. Electroforming processes such as LIGA allow structural thicknesses as great as 100 mu m with micron or submicron lateral features. The application of these processes and microstructures to neuroelectronic interfaces, mass flow and microflow sensors, and multichannel submicron surface profilometers is described. The extension of these approaches to complete integrated microsystems, realized monolithically or as multichip hybrids, is discussed, and applications in areas such as millimeter-wave components and vacuum microelectronics are examined. |

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.
