The Semiconductor Industry in the UK

techUK’s submission to the Business Energy and Industrial Strategy Select Committee’s inquiry



June 2022






























About techUK


techUK is a membership organisation launched in 2013 to champion the technology sector and prepare and empower the UK for what comes next, delivering a better future for people, society, the economy and the planet.


It is the UK’s leading technology membership organisation, with more than 850 members spread across the UK. We are a network that enables our members to learn from each other and grow in a way which contributes to the country both socially and economically.


By working collaboratively with government and others, we provide expert guidance and insight for our members and stakeholders about how to prepare for the future, anticipate change and realise the positive potential of technology in a fast-moving world.
























  1. Semiconductors are core part of the UK’s technology sector, we are world leaders in semiconductor design and lead in emerging manufacturing techniques such as compound semiconductors. UK designed and built chips have revolutionized the performance of mobile devices boosting computing power and energy efficiency, while new compound semiconductors are finding specific uses in 5G technologies and electric vehicles.


  1. techUK welcomes the confirmation in the recent Digital Strategy that the Government will bring forward a Semiconductor Strategy[1] that will aim to help further advance the UK’s expertise in semiconductor technologies.


  1. techUK represents over 850 technology companies with operations in the UK. This includes the designers and manufacturers of semiconductors as well as principal users such as manufacturers of complex machinery and consumer electronics. Therefore, we believe we provide a unique perspective that captures the almost complete value chain.


  1. Our analysis is that semiconductors are a key UK strength, and Government should work with industry stakeholders help the industry flourish. While supplies are expected to remain tight until 2023[2] the UK should resist demands to try and ‘onshore’ semiconductor manufacturing and instead take a more strategic approach to how we support the sector.


  1. In our response to the BEIS Select Committee’s inquiry we set out our response to the questions posed as well providing recommendations across (i) Government action, (ii) Research, Innovation and IP and (iii) Funding and investment that we believe would help support the future of the UK’s semiconductor industry. In summary these recommendations include:





Global semiconductor supply chains, security, and resilience:


Answer to Questions 1 and 2


  1. The onset of the COVID-19 pandemic has resulted in a persistent global shortage in the supply of silicon-based semiconductors. While COVID-19 sparked a major disruption the supply of semiconductors already was strained before the pandemic.


  1. A combination of factors including growing demand for consumer electronics and the intensification of demand from other business sectors (notably in automotive) as a result of increasing technology integration has resulted in a persistent demand overshoot for silicon semiconductor components. Factory closures during the pandemic heavily hit supply resulting in severe shortages in these types of semiconductors. This is not unique to the UK, and is a challenge that has been faced by economies around the world.


  1. Persistent shortages are caused by the cost and lead in times of developing new fabrication plants as well as localized factors that hit the high concentration of silicon-based fabrication plants around the South China sea (81% of semiconductor contract manufacturing is based in Taiwan or South Korea[3]). This concentration has also raised geopolitical concerns and has focused minds in the US, EU on how best to secure supply to products critical for their economic and national security.


  1. Despite these issues demand and investment in new capacity remains high. Our members believe a combination of continued demand and large investments in new high end chip capacity coming on stream will help resolve the current crisis. Therefore, the UK should focus its efforts to support the future of the semiconductor industry rather than seeking to address a problem which is likely to pass.


The UK’s semiconductor industry:


Answer to questions 3 and 4


  1. The semiconductor industry is highly specialised and integrated. There are three broad process steps in the supply chain: chip design, wafer fabrication and the combination of assembly, testing and packaging. These are underpinned by various elements that include IP, key materials, wafers themselves, and the advanced manufacturing equipment and facilities required for semiconductor production.[4]


  1. Division of Labour between companies across these three process steps as well as the complexity and specialisation required to effectively compete in the market has led to a high level of specialisation in the semiconductor industry and a clustering of high end companies. For example, 75% of manufacturing capacity is in China & East Asia while the U.S. has a 64% market share in chip design.[5]


  1. Although the UK has a relatively low share of the global semiconductor manufacturing base (there are 23 fabrication plants spread across the UK) the UK’s great strength is in semiconductor design and IP where we are world leading. The UK is host to 110 design firms including among them several of world’s leading companies[6] making the UK the clear leader in Europe as well as a significant player in the global value chain.


  1. These companies are fully aligned with the UK Government’s objectives to create a science and tech superpower, with high skilled workers supporting the development of ground-breaking technologies in AI, high performance computing, quantum technologies and beyond.


  1. There is often a false view that because the UK has a low share of global manufacturing the industry is not secure and more susceptible flight. This is not correct as highly specialist cutting edge design and IP is generated though established partnerships and clusters. These are often centred around leading universities and supported by strong innovation and financial institutions as well as good governance and regulation. For example, the Silicon Fen, or the Cambridge Cluster. There are currently over 1500 companies in the technology and life sciences sectors based in Silicon Fen, bringing in a total revenue of £14bn per annum[7].


  1. These clusters focused on intangible assets are extremely hard to replicate and therefore should not be viewed as less complex or more subject to flight than manufacturing capacity and provide the UK with its strong position in the global value chain. More therefore needs to be done to foster and support the development of the UK’s existing stock of companies and start-ups in these kinds of clusters. Doing so will be vital to continue to make the UK an attractive place to base, grow and potentially list these businesses in the face of significant global competition.


  1. Beyond design and IP the UK also has a growing market of compound semiconductors. While 80% of semiconductors use silicon, 20% use non-silicon-based compounds of two or more elements.[8] The UK has a strong materials science R&D, design and manufacturing base in these technologies which have a variety of potential applications including in 5G and electric vehicles, but also in clean energy, defence and space technologies.



The UK in the world, how we contribute to the global value chain:


Answers to questions 5,6,7 and 8


  1. In the global supply chain, the UK provides key IP and design inputs, supports exploratory work into the applications for compound semiconductors and is a destination for further developing the manufacturing processes for non-silicon chips.


  1. The design and IP produced by the UK’s semiconductor companies has led to revolutionary increases in computing power and power management allowing consumers to get access to more powerful and more energy efficient technology. While the applications of compound semiconductors continue to be explored. These inputs are vital for the global value chain making the UK and integral part, despite a relatively low manufacturing base.


  1. There has been a growing debate around whether the UK should seek to try and onshore some semiconductor manufacturing.


  1. Due to the high level of specialisation in semiconductor manufacturing barriers to entry into the market are extremely high. Attempts to onshore semiconductor manufacturing in the US and EU – via their respective CHIPS Acts – will require billions of dollars and Euros in subsidies to establish.


  1. Overall, these efforts to further diversify the global semiconductor supply chain should be welcomed however investment in these new manufacturing or fabrication plants will only be one part of a longer-term push to diversify the global supply of chips.


  1. Further while investments in new fabrication plants around the world will be vital to diversify supply, the global semiconductor industry is hugely varied as well as being highly specialised. Therefore, completely onshoring the supply and value chains of semiconductors cannot be practically achieved, even within large trading blocs such as the EU and US.


  1. Therefore, whether the UK undertakes similar efforts should be based on an assessment of whether such a heavy investment supports the UK’s existing strengths as well as comparing this with the opportunity cost of directing public investment to advance existing areas of UK excellence.


Supporting the Future of the UK’s Semiconductor Strategy:


Answers to questions 5,6,7 and 8


  1. The UK Government’s upcoming semiconductor Strategy should focus on the future of the industry rather than seeking to address an existing crisis which is likely to pass. We have made a number of recommendations below across (i) Government action, (ii) Research, Innovation and IP and (iii) Funding and investment.


  1. Skills should be a particular area of focus and we welcome efforts in the Digital Strategy to increase this focus on digital skills development and routes for international talent into the UK sector. Access to the right skills, talent and management will be extremely important for the sector’s future as a leader in design, IP and new manufacturing processes.


  1. As well as focusing on its existing specialisms and areas of opportunity the UK should be engaging with international partners to ensure that access to global markets can remain uninterrupted, securing supply chains as well as access to customers. This is particularly important with regards to Taiwan and the wider Southeast Asia region, given its position as a major part of semiconductor industry today.


  1. With the US and EU coordinating on technology trade the UK Government should also seek to foster similar partnerships – covering both the supply of semiconductors themselves as well as the raw materials that go into them – within its trade strategy and objectives. The UK Government should also look to foster international partnerships in academia and in the private sector.


  1. By continuing to remain a leading and highly specialised design and IP generating market as well as expanding its capabilities in non-silicon based conductors the UK will remain a key part of the international supply chain and therefore key to discussions around how value chains remain accessible to key markets.


  1. This position could be diminished if the UK lost its world leading edge in these core specialisms and therefore it is vital, we take action to support the future of the UK industry.


Recommendations to support the future of UK’s semiconductor industry:


Provides answers to questions 1,2,3,4,5,6,7 and 8


  1. Government action:







The Strategy should also ensure the UK’s full range of innovation support agencies UKRI, Innovate UK and ARIA and the British business bank are placed as key partners and supporters of the semiconductor industry, particularly for start-ups and innovative companies focused on nascent technologies such as compound semiconductors.




  1. Research, innovation and IP:





Of the companies that claimed this relief in tax year 2018 to 2019, 28% were classified as ‘Large’, but these companies accounted for most of the relief claimed (92%). Reviewing this scheme could increase the uptake among SMEs, tech start-ups and scale-ups who would be more likely to benefit from these wider range of IP rights.



  1. Funding and investment:





Continued application of the Act in this way, particularly to the semiconductor industry, will result in lasting damage to the UK’s reputation as a place to invest. This will particularly be the case if low-risk or previously routine investments continue to be delayed. The Government should therefore urgently review the application of the Act and engage via the NSI Expert Panel as well as wider market engagement to establish clearer standard operating procedures and guidelines for the exercise of the Act’s powers. This would give businesses greater certainty over investments and reduce nervousness around potential deals.
