| Abstract | By 2020 it is very likely that nano-CMOS will reach the end of the scaling roadmap. Such end will not mean the demise of silicon technology at all. While there are uncertainties as to what will be the show stoppers, there is a large number of transitional and compatible to CMOS technologies that will be more important than just 2D scaling. This paper discusses possible limitations bringing the end of scaling and also proposes a likely scenario for hardware technology evolution and related challenges for integrating systems in the next 20 years. The scenario beyond the end of the roadmap is drawn, in which key technologies will be developed to be compatible with nano-scaled CMOS in silicon, and not to replace it entirely. Transitional technologies will rather coexist and be built upon a basic CMOS-like technology platform of silicon-on-insulator. Radically new devices at the 1 – 10 nm scale will most likely be built on a silicon substrate with the same technical requirements (such as cleanness, lithographic resolution, long range ordering, etc) of near end-of-roadmap CMOS industry. The end of scaling will not necessarily lead to the onset of a post-silicon era. Advanced materials research has not pointed so far to a non-silicon scenario well beyond 2020. The computing systems challenges will be dealt with new forms of integration, hierarchically ordered from the micron-level, to sub-micron level (500nm to 100nm) non-digital, down to nano-scaled transistors on silicon further down to 10 nm. In this hierarchy, at the bottom, it is highly possible that disruptive molecular level devices (self-assembled in the scale of 2 to 10 nanometers) will eventually be production-worthy for 100 Giga to Tera-scale devices integration. Structures like graphene-based carbon tubes or planes are the most viable candidates for molecular devices. In this presentation the computer systems relevant issues of systems power dissipation, noise, hardware design complexity, and resilience to systems failures in the presence of device variances and faults, are addressed as the challenging computing research topics that will guide future research in computing architectures at the tera-scale integration beyond 2020. |

| Resource Type | Synopsis |
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.
