Abstract | Summary form only given. For two types of production-small-variety/large-volume production and large-variety production-CIM (computer integrated manufacturing) lines have been developed and constructed for the whole production process from wafer fabrication to final testing. Each wafer fabrication line is constructed with a block structure having a somewhat different pattern, depending on the production type. The wafer testing, assembly, and final testing lines are constructed on the basis of a linear structure with multi-passages. For small-variety/large-volume production, it is sufficient for the characteristics of the block structure to approximate those of the linear structure closely. The wafer fabrication line is divided into several blocks according to the process steps. Each block consists of modules in which several pieces of equipment are integrated using transfer robots, an in/out station, and, in some cases, temporary storage. For large-variety production, a block structure similar to a job-shop structure is more suitable for improving flexibility. The wafer fabrication line is divided, for example, into two blocks for the master and the slice levels. However, this type of line needs sufficient capacity and efficiency in the work transport system and a complex distributed network hierarchy architecture for the control system. |

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.
