| Abstract | Dielectric film etching represents one of the most challenging aspects of semiconductor processing. At present, a dielectric etch reactor must be capable of handling a range of dielectrics, such as doped and undoped silica glass, silicon nitride, organic anti-reflection layers and low-k dielectric materials of a predominantly organic composition. Successful etch tools perform the "critical" steps required for contact, self-aligned contact (SAC), via and dual damascene structures as well as the less critical steps such as spacers and passivation that are required by leading edge 0.25 /spl mu/m generation devices as they enter volume production. Finally, all the etches must be cost effective as measured with the standard metrics of cost of ownership (COO), and overall equipment effectiveness (OEE). In this paper, we describe how these metrics have been used to generate several product improvement programs for an advanced dielectric reactor, the 4520XL/sub E//sup TM/ from Lam Research. Both process and productivity improvements are shown for sub-0.3 /spl mu/m feature size devices. These improvements show promise for extension of the applicability of the 4520XL/sub E/ reactor to sub-0.2 /spl mu/m feature sizes. |

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.
