| Abstract | Summary form only given. The US EUV Lithography Program has focused on demonstrating all critical technologies essential for early access to production tools. In addition to individual components, techniques, and metrologies, a major effort was completion of the alpha-like tool, the Engineering Test Stand (ETS). Progress to date is based on a close collaboration between technical staff at the Virtual National Laboratory, consisting of Sandia, Lawrence Livermore, and Lawrence Berkeley National Laboratories, member companies of the EUV Limited Liability Company (Intel, Motorola, AMD, Infineon, Micron and IBM), and a wide array of vendors and suppliers. In this paper, we review progress on aspheric optical substrates, multilayer coating reflectivity and uniformity, scattering and flare. We briefly describe requisite visible light and at-wavelength metrologies. Progress on EUV masks (reticles) is reported, including specifications, patterning with candidate materials, inspection, and standards. Progress on sources of EUV radiation is reported, and related to recently published wafer throughput models. Results of wafer exposures are presented for two sets of optics. Looking to the future, emphasis is placed on collaborative efforts and partnering directed towards early access to beta and production tools. |

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.
