Reframing the Roadmap: ITRS 2.0

The International Technology Roadmap for Semiconductor (ITRS) is being reframed to focus more on end applications, such as smartphones and micro-servers. Labeled ITRS 2.0, the new roadmap is a departure from a strong focus maintaining the path defined by Moore’s Law. The original ITRS was published in 1992 at the National Technology Roadmap for Semiconductors; it became the ITRS in 1998.

In an IEEE paper published late last year titled “ITRS 2.0: Toward a Re-Framing of the Semiconductor Technology Roadmap,” the roadmappers explain why it’s time for a change. “As new requirements from applications such as data center, mobility, and context-aware computing emerge, the existing roadmapping methodology is unable to capture the entire evolution of the current semiconductor industry. Today, comprehending how key markets and applications drive the process, design and integration technology roadmap requires new system-level studies along with chip-level studies.”

The ITRS roadmapping committee has already been reorganized to focus on ITRS 2.0. There are now seven groups focused on what ITRS chairman Paolo Gargini calls the seven “building blocks.”

  • System Integration—studies and recommends system architectures to meet the needs of the industry. It prescribes ways of assembling heterogeneous building blocks into coherent systems.
  • Outside System Connectivity—refers to physical and wireless technologies that connect different parts of systems.
  • Heterogeneous Integration—refers to the integration of separately manufactured technologies that in the aggregate provide enhanced functionality.
  • Heterogeneous Components —describes devices that do not necessarily scale according to “Moore’s Law,” and provide additional functionalities, such as power generation and management, or sensing and actuating.
  • Beyond CMOS—describes devices, focused on new physical states, which provide functional scaling substantially beyond CMOS, such as spin-based devices, ferromagnetic logic, and atomic switch.
  • More Moore—refers to the continued shrinking of horizontal and vertical physical feature sizes to reduce cost and improve performance.
  • Factory Integration consists of tools and processes necessary to produce items at affordable cost in high volume.

Gargini, who will be delivering a keynote at address at The ConFab 2015, said he it was clear that the ITRS needed to change in 2010 when tablets were gaining much traction. “By 2012, I outlined to the ITRS groups that we were going to change. 2013 was a hybrid year where we were putting together the building blocks for the new environment. Then in 2014, that’s what we had done exclusively.”

A revised ITRS was not released at the end of 2014, as has historically been the case. Gargini said the groups have been preparing white papers which should be released early this year. We’ll be publishing summaries in Solid State Technology, so stay tuned.
