Semiconductor wars – identifying the likely winners.

Semiconductor wars – identifying the likely winners.

As published by Sanlam Glacier on 2 June 2023

There is old adage on Wall Street – “Semiconductors make the word go round.”

The entire $5 trillion IT and Electronic market is underpinned by the +$500 billion semiconductor industry. What’s more – is that it is expected to reach $1 trillion by the end of the decade. This means that an industry which took more than 40 years to reach its current size, will basically double within the next 7 years.

What is a semiconductor, and why do they matter?

People in general are blissfully unaware of the intricate and impossibly complicated technology beneath the covers of their cell phones and smart watches. From these shadows, semiconductors operate – literally making the modern world work – to the extent that the global tech-hotspot known as Silicon Valley has been named after the Silica used to make them.

The term semiconductor loosely refers to any integrated circuit, or microchip as they are more commonly known. The name refers to the base material (typically ultra-pure silicon) that is neither a conductor, nor an insulator of electrical current. Instead, its conductive properties can be altered to allow the flow of electrons. These electrons can be thought of as information travelling between transistors – microscopic “switches” communicating in binary code that are either on or off, 1 or 0 depending on the last performed action. This is an extremely simplified explanation of a very complex process. Chemistry lesson done.

Why they are so important and topical is the more pertinent question. Semiconductors are found in every conceivable electronic product: from laptops, airplanes and automobiles to medical equipment and military cruise missiles. They form the backbone of modern supercomputers, artificial intelligence engines, and big-data driven applications. This gives them tremendous strategic importance for any company, or more importantly – country – with ambitions of being at the bleeding edge of technological development. Predictably, this has also turned semiconductors, and the companies involved with their development and production, into something of a political bargaining chip. The clearest example of this was the US government effectively forcing its Dutch counterpart to block lithography giant ASML from supplying any of its latest generation equipment to China. ASML is the only company currently able to produce leading edge EUV lithography machines, and cutting China’s access to them effectively means they can only operate at the lagging edge. These geopolitical tensions have introduced a number of new variables into an already complicated equation.

Consider an industry that is notorious for its cyclicality – now throw sanctions against Beijing, the ever-present undertones of unification with Taiwan (by force if necessary), concerns about supply chain security leading to deglobalization, and multi-billion-dollar governmental subsidies into the mix – and the near-term prospects for the industry become…complicated, although its structural prospects can’t be disputed.

The main players.

There are three different segments at the bottom of the supply chain. Integrated Device Manufacturers (IDM’s) such as Samsung and Intel design and manufacture their own chips. Fabless players like AMD and Qualcomm only design chips. Foundries manufacture chips for these fabless players – this is where we find TSMC.

Over the last 20 years the number of players operating at the very leading edge in each segment of the industry have dwindled down to a point where they can be counted on one hand. This is true for IDMs and foundries. There are now a mere 3 companies – TSMC, Samsung and Intel who are able to produce chips at the leading edge – compared to roughly 25 in 2000.

Further up the supply chain are the capital equipment manufacturers (semicap), who make the individual components that IDM’s and foundry players need to make chips. Similarly, the market share of the top 5 semicap companies have increased from just over 50% to 70% over the past 2 decades. This is mostly due to the rapid pace of technological advancement and capital intensity required to stay competitive.

To get a better idea of how steep this development curve is, consider the following. Today’s advanced microchips – such as those in our smartphones – are roughly the size of a fingernail, but they contain billions of microscopic transistors. This is possible because companies are creating transistors so small, they need to be measured in nanometres – which is one billionth of a metre.


Fail to progress to the next technology iteration, and you can expect to be bumped off the bandwagon. Intel’s recent slip ups in manufacturing capability is a great example of this. While they remain very much relevant in the bigger scheme of things – failure to progress to the latest iteration has forced them to outsource production of their most advanced designs to TSMC – something that would have been almost inconceivable a number of years ago.

Identifying the potential winners.

The semiconductor industry seems to be at an inflection point – with a number of secular drivers becoming more evident. These include the advent of the big data era, Artificial Intelligence, Autonomous driving, 5G, Internet of Things etc. which all require more, smarter, and faster semiconductors. The industry therefore must keep evolving and creating more complex structures in an attempt to decrease size and power consumption, while increasing performance, in an effort to keep up with Moore’s Law. This is one of several drivers positioning the capital equipment providers more favourably compared to other segments over the coming years.

Reshoring of global supply chains is another factor that is bound to introduce inefficiencies into the system. Pulling on the short straw of these changes we will likely find TSMC, Intel, and Samsung – as they might have to operate more factories at sub-optimal utilization levels. The most likely benefactors will be companies tasked with kitting out these factories – i.e., the semicaps, as they will be churning out more equipment per unit produced.

Why we prefer Applied Materials.

One of the largest of these equipment manufacturers which looks poised to capitalize on this trend over the long term is Applied Materials.

As a semicap player, they sit further up the supply chain, which means they are generally more cyclical than IDM’s and foundry players. This has led to their share price selling off to a greater extent during this cyclical downturn in semiconductors, even though there has been no impairment to their long-term prospects.

They have the broadest range of products and services within the industry, which provides them with valuable insight into the most pressing challenges faced by clients. An R&D budget of billions of dollars and a portfolio of more than 15 000 patents enables them to be a key player in solving some of the industry’s most difficult challenges. Lastly, their fortress balance sheet and high levels of free cash flow generation has enabled them to deliver good returns, while reducing the number of shares outstanding by 25% over the last 5 years.

Despite short-term headwinds., Applied Materials is well positioned to weather this and continue delivering strong returns to shareholders.
