TSMC & Samsung Foundry Could Build Leading-Edge Fabs in Europe

The EU wants leading-edge semiconductor manufacturing facilities

The European Union has been a semiconductor production power, but the recent tensions between the U.S. and China, as well as the Trump administration's tepid attitude towards European allies, has caused EU authorities to rethink a number of the union's policies. Among other things, the European Union is reconsidering its reliance on chips developed and manufactured overseas. So far, the EU has kicked off its supercomputer initiative, CPU initiative, and is now reportedly proposing leading foundries to build a leading-edge fab in Europe.

Strengthening the Competitiveness of European Industry and Science

The vast majority of chips that the industry uses are developed in the U.S. However, several companies in Europe still design chips for automotive, IT, and telecom industries or at least use them, including Ericsson, Infineon Technologies, Nokia, NXP Semiconductors, and ST Microelectronics. 

Not a lot of chips are actually made in Europe, though. Infineon, NXP, and STMicro produce some of their semiconductors at their own fabs but outsource a significant part of their chips to contract chip makers. GlobalFoundries, which once was part of AMD and produced the world's fastest microprocessors, transferred its leading-edge production to the U.S. over a decade ago and ceased to develop advanced nodes in 2018.  

Today, the EU cannot build a petascale or exascale supercomputer using components developed and made on the continent. Meanwhile, high-performance computing (HPC) is used widely to solve various complex industrial and scientific challenges. Without appropriate technologies, Europe completely depends on chips designed in the U.S. and made in Asia. 

The European authorities understand why these technologies are important, so the European Processor Initiative and the European HPC Initiative were launched in recent years. Meanwhile, to properly support both plans and be self-sufficient in terms of chip supplies, Europe needs its own semiconductor production industry to produce chips using mature, specialty, and cutting-edge fabrication processes. In fact, the EU wants to produce 20% of the world's chips and processors (by value) eventually, up from 10% today. 

"Without an autonomous European capacity on microelectronics, there will be no European digital sovereignty," said Thierry Breto, a European Industry Commissioner, in a speech, reports Bloomberg

Last year 17 EU member states signed a declaration to develop next-generation CPUs and leading-edge process technologies to make them. The states intend to invest $145 billion in such development and enhance cooperation, reports EE Times. The declaration precludes the launch of a European alliance on microelectronics, which is expected to happen in late Q1 2021. The alliance is projected to include the EU's major chipmakers, telecom companies, carmakers, and producers of medical and other high-tech equipment. 

Catching Up with Asia

There are several ways for the EU to catch up with South Korea (Samsung Foundry) and Taiwan (TSMC) when it comes to fabrication processes. 

One approach is to consolidate local chipmakers, fund development of both cutting-edge and specialty process technologies, and then provide financial help to build leading-edge fabs in Europe. Another way is to lure Samsung Foundry and/or TSMC to Europe with various incentives. Either plan is hard to accomplish, but it is even harder to make either of them work over the long term.  

Firstly, it is close to impossible for GlobalFoundries and STMicro to catch up with Samsung Foundry and TSMC in the foreseeable future in terms of R&D. Since it is hardly possible for European chipmakers to quickly catch up with their Asian rivals, inviting companies from South Korea and Taiwan to Europe may be a somewhat more realistic idea. 

Secondly, there aren't many European chip designers that require top-notch process technologies. Even fewer require the volumes that justify building an advanced fab that has to work at a nearly 100% utilization rate to be profitable. Recently Daimler, Volkswagen, and some other automakers complained that they could not procure enough chips from TSMC as the latter was busy making chips for other customers. The lack of chips significantly affects automakers and local economies as the automotive industry employs tens of thousands of people. Yet, chip consumers like automakers do not really use brand-new nodes and do not require large volumes of chips. For example, only about 3% of TSMC's revenue comes from the automotive industry.  

Thirdly, semiconductor manufacturing facilities need to be upgraded often to stay on the cutting edge, which means regular investments and regular demand for advanced nodes from customers. So, to actually lure foundries to Europe, incentives alone are not enough. To make chip production viable on this side of the pond, a full-blown semiconductor industry that includes both designers and large consumers is needed. 

Foundries Need to Mitigate Risks Too

A report from DigiTimes this week implied that TSMC might be actually considering a fab in Europe partly because if geopolitical tensions intensify and disrupt traditional semiconductor supply chains, it will risk losing customers. Samsung Foundry may think the same way too.

"When it comes to fab location selection, we need to consider many factors including customers' need," spokeswoman Nina Kao told Bloomberg last week when asked about cooperating with Europe. "TSMC does not rule out any possibility, but there is no concrete plan at this time." 

It is noteworthy that companies like Intel and GlobalFoundries have manufacturing facilities on different continents, though GlobalFoundries offers different technologies at different fabs.
