International Technology Roadmap for Semiconductors



The International Technology Roadmap for Semiconductors (ITRS) is a set of documents produced by a group of

The documents carried disclaimer: "The ITRS is devised and intended for technology assessment only and is without regard to any commercial considerations pertaining to individual products or equipment". The documents represent best opinion on the directions of research and time-lines up to about 15 years into the future for the following areas of technology:

, or any semiconductor device, requires a series of operations—photolithography, etching, metal deposition, and so on. As the industry evolved, each of these operations were typically performed by specialized machines built by a variety of commercial companies. This specialization may potentially make it difficult for the industry to advance, since in many cases it does no good for one company to introduce a new product if the other needed steps are not available around the same time. A technology roadmap can help this by giving an idea when a certain capability will be needed. Then each supplier can target this date for their piece of the puzzle. With the progressive externalization of production tools to the suppliers of specialized equipment, the need arose for a clear roadmap to anticipate the evolution of the market and to plan and control the technological needs of IC production. For several years, the

(SIA) gave this responsibility of coordination to the United States, which led to the creation of an American style roadmap, the National Technology Roadmap for Semiconductors (NTRS). In 1998, the SIA became closer to its European, Japanese, Korean, and Taiwanese counterparts by creating the first global roadmap: The International Technology Roadmap for Semiconductors (ITRS). This international group has (as of the 2003 edition) 936 companies which were affiliated with working groups within the ITRS. The organization was divided into Technical Working Groups (TWGs) which eventually grew in number to 17, each focusing on a key element of the technology and associated supply chain. Traditionally, the ITRS roadmap was updated in even years, and completely revised in odd years. The last revision of th

ITRS 2.0

In April 2014, the ITRS committee announced it would be reorganizing the ITRS roadmap to better suit the needs of the industry. The plan was to take all the elements included in the 17 technical working groups and map them into seven focus topics: *;'' System integration'': This is a design-focused topic that examines architectures, and how to integrate heterogeneous blocks. *;''Outside system connectivity'': Focuses on wireless technologies, how they work, and how to choose the best solution. *;''Heterogeneous integration'': The focus will be on integration of separately manufactured technologies into a new unit so that they function better than the individual pieces do separately - whilst allowing for components such as cameras and microphones. *;''Heterogeneous components'': Focuses on different devices that form heterogeneous systems, such as
MEMS Microelectromechanical systems (MEMS), also written as micro-electro-mechanical systems (or microelectronic and microelectromechanical systems) and the related micromechatronics and microsystems constitute the technology of microscopic devices, ...

Chapters on each topic were published in 2015.ITRS 2.0 chapters
