The Heterogeneous Integration Roadmap for Aerospace and Defense

Reading time ( words)

Semiconductor Roadmap History
Most people in the semiconductor industry are familiar with the International Technology Roadmap for Semiconductors (ITRS), which provided guidance for the industry starting in 1991 (as the National Technology Roadmap for Semiconductors). As the benefits of Moore’s Law became more difficult and more expensive to achieve, the organization decided to publish a final version in 2016. The baton was handed to the Heterogeneous Integration Roadmap (HIR), with the realization that heterogeneous integration—assembling different types of devices rather than monolithic fabrication—is an important enabler for continued progress in the semiconductor industry.

The aerospace and defense segment of the semiconductor industry has unique needs in terms of technology, security, supply chain, and lifecycle. Heterogeneous integration is a critical technology that intersects all of these challenges, so the HIR organization identified aerospace and defense (A&D) as one of the topics to have a chapter and a technical working group (TWG) that specifically targets the unique requirements of aerospace and defense. The HIR identifies challenges in 5-, 10-, and 15-year horizons and provides guidance on how to meet those challenges. This is, of course, a perpetual work-in-progress and will be updated as capabilities move forward and new requirements arise.

Initial Scope
The initial version of the A&D chapter published in 2019 is focused largely on challenges and requirements for the U.S. Aerospace and Defense Industry. The intent of the HIR is to create a document that provides guidance that is useful to the semiconductor community around the world, so the U.S.-centric viewpoint should be seen as just the starting point for this work. There are certainly many technical challenges that are pervasive throughout the international A&D industry, such as reliability, bandwidth, thermal management, radiation hardening, long product development cycles and lifetime, and supply chain security, so much of the content can be generalized beyond the U.S. aerospace and defense industry. Future revisions of this chapter will reflect that broader scope.

2020 Update
The 2020 updates to the A&D chapter in the 2019 edition include: (1) updates on government-funded heterogeneous integration programs, (2) recent relevant market data, and (3) the 0.1 version of the A&D Roadmap table.

Catching Up With Alpha Circuit’s Prashant Patel

04/05/2022 | Dan Beaulieu, D.B. Management Group
There is plenty of evidence that the American PCB industry is going through a revitalization. While a few new companies are being established, others are being rejuvenated as investors gain more interest and confidence in domestic PCB companies. I reached out to Prashant Patel, owner and president of Alpha Circuit Corporation in the greater Chicago area. I wanted to hear about his investment and the unique path he took to owning a PCB shop.

James Webb Space Telescope en Route to Discover Origins of the Universe, Study Exoplanets

01/06/2022 | Thales
A joint program between NASA and its counterparts in Europe (ESA) and Canada (CSA), Webb will observe the beginnings of our Universe by reaching back in time to just a few hundred million years after the Big Bang. It will also observe exoplanets – planets outside the Solar System – that are comparable to our own, as well as the formation and evolution of stars and galaxies. The ultimate aim of this successor to the iconic Hubble space telescope is to discover galaxies that reach back to the relative beginnings of the Universe. This state-of-the-art time machine is expected to revolutionize all aspects of modern astronomy. It will unveil the hidden side of the Universe, namely stars enveloped in clouds of dust, molecules in the atmosphere of other worlds, and the light issuing from the first stars and galaxies.

DoD Faces Growing Risks from Reliance on Lead in Electronics

12/13/2021 | Chris Peters, USPAE
Like a cancer that spreads untreated until it becomes an urgent problem, the U.S. defense community is facing a small but growing problem that is increasingly undermining U.S. military readiness and technological dominance. The problem is lead—specifically, the lead-alloy solders that traditionally have been used to attach electronic components to printed circuit boards (PCBs). Over the last 15 years, the commercial electronics industry has shifted to lead-free solders, prompted by environmental health regulations in Europe and elsewhere. However, the U.S. Department of Defense (DoD) and its contractors never made the switch and are still heavily reliant on leaded solders. Now, leaded electronics are becoming harder to find and more outdated.
