Council for Science and Technology: advice on building a sovereign AI chip design industry in the UK

Executive Summary

Semiconductors (or ‘chips’) have rightly been recognized by the authorities as a precedence know-how for the way forward for the UK^{[footnote 1]}. Their improvement and utilization underpin lots of our strategic objectives, reducing throughout sectors, and they make a vital contribution to our ambitions for financial progress and safety^{[footnote 2]}.

The UK has a area of interest and extremely specialised chip industry, so it’s unlikely that the UK will ever catch as much as the present front-runners by taking a broad, generalist method. If we’re to see financial returns for the UK, the authorities should focus funding and exercise on the elements of the chip industry the place the best progress is predicted and the place the UK can obtain strategic benefit.

There is rising consensus that over the subsequent 10 years the quickest rising a part of the world chip industry might be in AI chip merchandise (accelerators, recollections, Graphics Processing Units (GPUs), Central Processing Units (CPUs), interconnects and packaging). The world market for AI chips is forecast to develop at roughly 30% per 12 months from now to 2030, at which level AI chips might be over 50% of world semiconductor income.

Fortunately, with the proper funding and capabilities in place, the UK may create a significant AI chip design industry. We have sturdy AI and design experience and creativity in our universities; a rising ecosystem of AI corporations; and ARIA’s Scaling Compute program has recognized and introduced collectively, for the first time in the UK, expertise and concepts with the potential to create novel vertical AI programs^{[footnote 3]}. However, this could require daring commitments from the authorities to place the proper foundations in place, together with the coaching of an AI chip workforce. We consider that is possible a once-in-20-years alternative for the UK to construct a worthwhile AI chip design industry in 1 of the largest markets in the world.

Our suggestions cowl the abilities (suggestions 1 and 2), finance and funding (suggestions 3 and 4) and infrastructure capabilities (suggestions 5 and 6) the UK would want to construct to realize this:

Background

1. The subject of semiconductors (or ‘chips’) is a sophisticated subject in the UK, and generates spirited debate about authorities’s position, what its priorities must be, and how a lot it ought to make investments.

2. There is a nationwide tendency to conflate chip design (1 of the quickest rising industries in the world) with chip manufacturing (1 of the most costly industries in the world). It helps to be clear that the 2 industries are fully completely different, with completely different dynamics, requiring completely different talent units and very completely different ranges of funding. At a excessive stage, a chip designer is like an architect whose output is the detailed design of a building. A chip producer is like a building agency, who takes these drawings to construct a completed product.

3. Today, it prices roughly $50-100 million to design a modern chip, about $100 million to fabricate the chip, and about $20 billion to construct a manufacturing plant (‘fab’)^{[footnote 4]}. Chips are designed by startups, chip distributors (e.g., Nvidia, Intel, AMD) and by massive know-how corporations (e.g., Apple, Google, Amazon Web Services) utilizing specialised digital design automation instruments (e.g., from Cadence and Synopsys). Chip manufacturing is extra of a ‘nation state activity’: Taiwan Semiconductor Manufacturing Company (TSMC) began due to vital funding by the Taiwanese authorities, therefore the US and EU CHIPs Acts to stimulate extra world range (e.g., Intel, Global Foundries, Tower).

4. The UK chip industry has declined since its peak, resulting in a lack of confidence, and disagreement over the place, how and whether or not to rebuild. The first business pc, the first digital reminiscence, the first parallel pc (the Inmos Transputer) and the first extensively used chip IP mannequin (ARM, whose licensed CPU designs are in nearly each smartphone in the world) all occurred in the UK. However, with ARM’s possession by Softbank, its itemizing on Nasdaq and with a majority of its staff exterior the UK, it feels to some like a misplaced alternative.

5. The UK has a energy in non-standard manufacturing processes primarily based on compound supplies. About 80-90% of the world’s chips are constructed from pure silicon: that is how CPUs, GPUs, recollections and the majority of chip designs are manufactured. The remainder of the market consists of compound supplies, together with silicon-germanium (SiGe) for high-speed RF circuits, aluminium-gallium-arsenide (AlGaAs) and indium-phosphide (InP) for optoelectronics, and gallium-nitride (GaN) for energy electronics. Southampton’s world-class Optoelectronics Research Centre (ORC) has created a native industry over a few years in fiber optic communications, specialised lasers and chip-to-chip communications. GaN is a more moderen UK energy, with rising experience, startups and funding in energy electronics.

The North Star: A worthwhile UK industry for AI chip design

6. The AI Opportunities Plan^{[footnote 5]} outlined the Prime Minister’s intent to take a position closely in AI, with 3 main objectives, one among which is to “position the UK to be an AI maker, not an AI taker.”  However, the Plan is quiet on UK-designed chips for AI regardless of the alternative and the dangers.

7. Between now and 2030, the world market for semiconductors is forecast to develop at roughly 8% per 12 months (from $625 billion in 2024 to $1 trillion in 2030)^{[footnote 1][footnote 6]}. The world market for energy semiconductors is estimated to develop at round 4% per 12 months (from $40-50 billion in 2023 to $50-60 billion in 2030). The world market for optoelectronic semiconductors is predicted to develop at about 7% per 12 months ^{[footnote 7]}.  Yet, the world market for AI chips is forecast to develop at 30% per 12 months from now to 2030^{[footnote 8][footnote 9][footnote 10]}, at which level AI chips will comprise over 50% of world semiconductor income.

8. AI chips are forecast to be the largest progress space in the chip industry for the subsequent decade, with 6 of the 7 largest corporations in the world investing billions the place they understand low hanging fruit for extra environment friendly, quicker, decrease energy AI chips.

9. There are due to this fact disproportionate alternatives for companies, and nations, with the proper capabilities. And, as corporations like Nvidia proceed to show, it’s attainable to achieve success and worthwhile even by way of a fabless method. As the UK authorities considers the place to prioritise funding over the subsequent 4 years, we suggest particular focus is given to AI chip design in the UK.

10. In the absence of a sovereign AI chip industry, we danger AI information centres in Growth Zones stuffed with graphics processing models (GPUs) from a single dominant provider, which is problematic for many causes. History reveals that a vendor with 90% market share and 75% gross margin shouldn’t be sustainable. When the market diversifies, which it inevitably will, there is a chance for the UK to have a stake. It would additionally assist us safe our {hardware} provide chain for home business and army purposes, in an unsure period of tariffs and export restrictions.

Recommendations

11. Building a worthwhile AI chip design industry in the UK will first require us to ascertain the proper situations, which in flip require a possible goal for the UK: to create the surroundings for new and present UK corporations – together with small, medium and massive corporations, and UK headquartered or outpost design centres from abroad – to launch 50 new AI chip merchandise in 5 years. Achieving this could require daring commitments from the authorities to create the foundations for success.

Skills

12. Estimates primarily based on DSIT’s most up-to-date evaluation of the UK semiconductor workforce present the present UK chip industry already wants roughly 7,000 new chip designers over the subsequent 5 years^{[footnote 11]}. If the UK had been to launch fifty new AI chip merchandise over the subsequent 5 years, it might require a additional 5,000 chip designers (roughly 100 chip designers per design^{[footnote 12]}, resulting in a whole of 12,000 new chip designers over the subsequent 5 years.

13. Today, we graduate about 9,000 digital engineers per 12 months^{[footnote 13]}, and if simply 10% change into chip designers, we might solely produce 4,500 chip designers in 5 years, simply over a third of what we are going to want.

14. To enhance provide, the UK ought to practice extra chip designers at our universities (by way of undergraduate and Masters programmes), entice chip designers to the UK, and collaborate with third occasion organisations (e.g., Interuniversity Microelectronics Centre (IMEC)) to whom we will outsource work. Preliminary plans to fund bursaries on to college students who research semiconductors are a very welcome step in the proper path.

15. UK universities might want to reintroduce electronics and chip design programs for undergraduate and masters college students, programs that had been extensively taught in the previous, however now solely provided by a few. These programs ought to cowl pc structure, chip design, verification and validation, in addition to optoelectronics.

16. We can and ought to rely on our centres of excellence (e.g., Edinburgh, Bristol, Southampton, and Sheffield) in these disciplines to assist create programs and then share course materials nationwide to ramp up rapidly. A nationally curated curriculum may speed up widespread adoption. Lessons must be learnt from the Taiwan Semiconductor Manufacturing Catapult Fin Field impact Transistor (TSMC FinFET) University program.

17. The course may embrace entry to chip design companies in collaboration with corporations akin to IMEC and Muse Semiconductors, each of whom provide privileged entry to TSMC’s FinFET University Program, giving college students expertise with superior 16nm and 7nm PDKs and fabrication processes. These programmes may also help with decrease price entry to superior EDA instruments.

18. It is extensively predicted that AI chips will more and more be interconnected utilizing optical communications, which in flip will possible increase the optoelectronics industry (past its present 7% Compound Annual Growth Rate).

19. Adjacent racks of AI servers will proceed to be linked by lots of of optical cables, powered by fiber-optic modules. Servers inside the racks, that are normally linked by copper cables at this time will be unable to maintain up with demand, and copper will more and more get replaced by short-reach optical cables. The accelerator, reminiscence and interconnect chips that comprise the server might be more and more co-packaged with optoelectronic chiplets (photonic built-in circuits or PICs).

20. To give a sense of the magnitude of communication inside an AI system: at this time, the information communications inside a single cloud information centre is about 10,000 instances bigger than the complete public web. A single rack of AI accelerators talk about 10 instances quicker than an equal rack of CPUs. Hence AI programs already require extra communications and are rising quicker nonetheless.

21. This is sweet information for the UK due to our energy in all facets of optoelectronics from optical subsystems and modules to specialised manufacturing. We can anticipate far bigger progress in manufacturing processes for optoelectronics than different compound manufacturing.

22. IMEC has a good optoelectronics programme and has entry to trendy vanguard business silicon-photonic manufacturing processes. There is probably going a possibility for better collaboration and leverage of IMEC, permitting us to keep away from any pointless replication, notably for costly manufacturing functionality. Our focus in the UK must be on the abilities and coaching for future optoelectronic engineers.

Targeted funding and finance

23. Today, the MOD and DSIT seem to analyse and work with the semiconductor industry independently of one another, though each are aligned in their reasoning: to hunt UK sovereign experience in chip design, packaging and manufacturing; to create a resilient provide chain in a time of world uncertainty; and to take a position in UK-sovereign AI chip merchandise.

24. It is a misplaced alternative that DSIT and MOD don’t coordinate extra intently on their evaluation and spending, notably as there are vital dual-use alternatives throughout industry and defence. There is ample low-hanging fruit in the creation and early-stage funding, which may later be funded for dual-use by the National Security Strategic Investment Fund (NSSIF).

25. We have a small variety of AI chip startups proper now, typified by Fractile, headquartered in London and with chip designers in the UK. There are only a few different UK AI chip startups.

26. If the UK is to play a massive world position in AI, we’d like extra corporations designing AI chip merchandise in the UK. Government has introduced promising plans in the Spending Review to considerably enhance funding and funding in UK know-how corporations in a extra coordinated manner by way of the complete pipeline. This consists of:

• Innovate UK grants for very early stage spinouts and startups growing new applied sciences and merchandise
• NSSIF funding in early stage corporations for safety, defence and dual-use functions
• Sovereign AI Unit funding for AI-specific applied sciences at varied phases
• British Business Bank (BBB) funding in early and progress stage alternatives
• The National Wealth Fund (NWF) making massive investments in vital UK infrastructure.

27. However, authorities can go additional by delivering a prioritised listing of applied sciences and sectors – outlined by DSIT, MOD, DBT and HMT primarily based on the UK’s strategic and financial objectives. For the progress of the UK AI chip design industry, this could embrace specific steerage on the kinds of enterprise which are essential to ship towards nationwide objectives, the underpinning applied sciences and infrastructure required for them, and the sorts of interventions required at every stage of the pipeline for them to succeed.

28. DSIT and HMT ought to advise Innovate UK to make grants to dangerous early-stage ventures, and NSSIF and Sovereign AI ought to make investments in the early, capital intensive section the place expertise, design instruments and multi-project wafers are costly; ideally alongside different buyers, on phrases to encourage participation.

29. DSIT and HMT ought to empower the BBB to take a position in the early phases and in the progress section, the place ‘tapeout’ prices are excessive, to get new merchandise into manufacturing, whereas enabling corporations (headquarters and outposts) to remain in the UK. The BBB must also recruit specialists or search exterior experience to assist determine AI chip corporations to take a position in, and to bolster its due diligence.

30. The BBB ought to make investments to encourage extra enterprise capital (VC) funding of AI chip corporations, together with investing in VC funds keen to decide to a minimal fraction of their investments in UK semiconductors.

31. The NWF ought to determine and fund infrastructure to help clusters of chip design corporations, in addition to superior chip packaging corporations, notably for the quickly rising market for excessive density chiplets in a single package deal or on a single panel.

32. All such investments, all through the pipeline, would require vital enter and advice from skilled members of the UK chip industry – the UK has many to name on, and we encourage all funding our bodies to take full benefit of the resident experience.

33. Targeted funding might require trade-offs to be made. Although the UK has a historical past of investing in compound supplies, DSIT ought to think about deprioritising them in favour of exercise in help of AI chips. Within the subject of compound supplies, optoelectronics ought to proceed to be a comparatively excessive precedence as the market for it’s anticipated to develop at a better charge.

34. There might be continued innovation in superior chip meeting and packaging, and this a part of the industry will proceed to develop due to the demanding necessities of AI chips. Government ought to discover funding in superior chip meeting and packaging.

Infrastructure

35. Stakeholders have famous that the present remit and capabilities of catapults akin to the Compound Semiconductor Applications Catapult should not greatest serving SME chip corporations and teachers who want inexpensive and well timed entry to services. Catapult companies are additionally usually costly and time to market is sluggish. The above suggestions can solely be delivered by way of a coordinated UK semiconductor sector with a vital mass of functionality. The UK Semiconductor Centre might be a optimistic step in direction of offering this coordination and authorities must be daring in deprioritising funding for infrastructure which isn’t match for goal.

36. Although we suggest pursuing a fabless method, the place chip fabrication is outsourced to an abroad foundry, UK startups would require entry to modern applied sciences akin to masks and multi-project wafers (MPWs), and licenses for Electronic Design Automation (EDA) instruments and Process Design Kit (PDKs).

37. These applied sciences are costly, and usually held by main chipmakers primarily based abroad, akin to TSMC, Samsung, and Intel.

38. While startups can negotiate immediately with chipmakers for entry, this can be prohibitively expensive, so the UK ought to look to barter as a nation, embrace entry and licenses in the negotiation of worldwide commerce agreements, or allow entry as a part of the UK funding mechanisms set out at advice 4. DSIT, DBT, MOD and HMT ought to think about the want for entry to those applied sciences as a part of their evaluation and coordination.

39. The UK might want to think about encouraging uptake of the TSMC University FinFET programme, which is a promising manner for college students (undergraduate, masters or retraining) to work by way of the full semiconductor design course of with entry to key applied sciences. Government ought to set up a nationwide settlement with IMEC (and think about establishing them with corporations like Muse Semiconductors) to streamline and scale back price for small UK corporations.
