| Abstract | Summary form only given. The semiconductor industry has witnessed a successful introduction of copper based interconnects and low permittivity insulators with 130nm node devices. The advent of 90nm node devices has led to the introduction of first generation of carbon doped dielectric films. Further scaling will require materials with lower permittivity and this has accelerated the development of a second generation of carbon doped oxides with imbedded porosity. While the addition of carbon to a silicon based dielectric lowers the permittivity of the insulator, carbon doping may also lead to degradation in the surface properties of such films. Frequently, carbon enrichment at surfaces is known to cause issues with the wetting characteristics of the surface. In addition, the mechanical strength of interfaces formed with carbon enriched surfaces may be poor compared to congruent surfaces. The high number of chemically and morphologically different materials in the integrated interconnects structure increase the possibility of mechanical structural failure. A detailed understanding of the basic material properties and the behavior of the carbon doped materials during subsequent processing is therefore of prime importance. This paper will present an overview of process and film property characterization of different generations of carbon doped oxides. Integration properties of these films and correlation to processing parameters and physical properties of the materials will be discussed. Novel processing techniques are discussed that enable the implementation of advanced low dielectric constant materials without sacrificing the high volume manufacturability of such films. |

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.
