Laser ion source produces a new generation of semiconductors

For ion implantation, that is 'hammering' ions into the surface layer of the material, conventional ion accelerators are commonly used. Laser ion sources are much simpler, cheaper and more universal. However, they emit wide energy ions usually accompanied by some admixtures. In the Institute of Plasma Physics and Laser Microfusion in Warsaw a unique laser ion source has been built which is equipped with a special system for accelerating ions to a chosen energy and for eliminating admixtures.

Significant step towards engineering contact modules with vertical carbon nanotube interconnects

Imec researchers, in collaboration with Tokyo Electron, have successfully integrated and characterized carbon nanotubes (CNT) into 150nm contact holes with a TiN underlayer and a Cu single damascene top contact module. The process steps are CMOS-compatible and the platform is designed for fast and automatic electrical testing and for benchmarking different CNT recipes and process conditions.

Adoption of the new definition of nanomaterials by the European Commission: first reactions and analyses

This Tuesday, October 18, the European Commission published its long-awaited definition of nanomaterials after a year of intense negotiations. The reactions were not long in coming, revealing power struggles so far mainly confined to Brussels area. Here is a first insight into the politics hidden behind this supposedly neutral and "scientific" definition, the next obstacles and important meetings.

Shining light on carbon nanotubes

Their size makes carbon nanotubes difficult to detect, examine and manipulate. Michael Blades, a senior electrical engineering and physics double-major, worked on this problem last summer in a research internship with Lehigh's Environmental Initiative.

Global carbon nanotubes market – industry beckons

More than 100 companies around the world today are manufacturing carbon nanotubes and this number is expected to increase to more than 200 within the next five years, while there are more than 1,000 companies and institutions that are actively engaged in CNT research and development. This article looks at the market size, applications, processing technology and end-user products of carbon nanotubes. In addition, the study looks at industry leaders in the value chain, potential applications, products which are under development and are likely to enter the market in the next five to ten years. For this study, we have surveyed industry professionals/stakeholders in the CNTs value chain, extracted information from our proprietary in-house databases/ inter-linked databases as well as researched other primary and secondary sources and triangulated data and the findings are presented in this article.
