• Understanding semiconductor science to invest in ETFs
From smartphones in our pockets to the laptops on our desks, from electric vehicles roaming the streets to the commercial jets flying above us, there is a common piece of material that enables the functionality of these modern marvels: semiconductors.
The world’s first working integrated chip (IC) — more commonly known as the microchip — was built on a piece of semiconductor material back in 1958. Today, semiconductors are the foundation of contemporary technologies.
These semiconductors are ubiquitous components of microchips, transistors and other electronic segments. Without semiconductors, numerous technological wonders will not be possible.
The opportunities are endless for semiconductor firms to profit from the rapidly changing technological landscape. The prolific growth of 5G, cloud computing, AI, electric vehicles and the Internet of Things (IoT) is expected to fuel the next demand spurt for chip-related products.
It is estimated that the semiconductor market will grow from US$513 billion (690 billion) in 2019 to US$726 billion by 2027.
Types of semiconductor firms
There are three main business models in the semiconductor industry: fabless, foundries and integrated device manufacturers (IDM).
The semiconductor supply chain fans across many stages, with some companies specialising in certain niches and others focusing on the verticalisation of the entire supply chain. On average, it can take up to three to five years to progress from initial research to final products.
To remain competitive, semiconductor companies have to invest significant money in R&D for chip design and/or manufacturing each year.
1. Fabless companies
A fabless company designs, markets and sells hardware while outsourcing the fabrication of that hardware to a third-party foundry. Examples of fabless companies include Apple, Nvidia, Advanced Micro Devices (AMD) and Qualcomm.
Fabricating hardware internally requires significant resources, which can lead to reduced profit margins. Specialisation allows fabless companies to channel their capital to the R&D of new technologies while benefitting from the expertise of external pure-play foundries.
For decades since its inception in 1969, AMD was involved in the entire production process of its microchips. However, in 2009, the company decided to divest its manufacturing operations and formed Globalfoundries. AMD eventually gave up its shareholding in Globalfoundries in 2012 and transitioned successfully to a fabless company.
This strategic move was integral for underdog AMD to compete against semiconductor giant, Intel, in the PC chip space. By outsourcing the fabrication of its Ryzen CPUs, AMD was able to undercut and wrest market share from rival Intel.
As of January 2021, AMD was on the cusp of overtaking and ending Intel’s dominance in the desktop CPU market.AMD’s market share stood at 49.8% while Intel had 50.2%.
2. Foundries
Pure-play foundries are chip fabrication companies that do not have design capabilities. They focus solely on IC manufacturing. Many of these foundries are located in Taiwan and China, where skilled labour remains plentiful and cheap.
Presently, the cost of developing a new fabrication facility that could compete with the established players could cost more than US$10 billion. Coupled with the economies of scale enjoyed by the existing foundries, barriers to entry for new entrants are formidable.
This also provides an added incentive for semiconductor companies to adopt a fabless business model, to exploit the comparative advantag
es of foundries. Fabless and foundry companies have a symbiotic relationship and their strategic alliance is called the fabless-foundry model.
Taiwan Semiconductor Manu
facturing Co (TSMC) pioneered the foundry business in 1987. Today, it is the largest independent manufacturer of microchips, with a market share of more than 50%.
For instance, Apple is TSMC’s largest client, accounting for about onefifth of its annual revenue. TSMC’s clientele comprises other technological titans like Nvidia, AMD, Broadcom and Qualcomm.
Furthermore, TSMC’s continued investment in advanced wafer technologies and cutting-edge manufacturing processes has enabled it to be a leading producer of 5nm chips for its clients. Production of the 3nm chip by TSMC is forecast to commence in 2022.
As a result, TSMC is expected to strengthen its position in the highly competitive foundry industry for the foreseeable future.
3. Integrated device manufacturers IDMs are companies that are engaged in the entire supply chain — from designing, manufacturing to the sale of IC products. Intel and
Samsung Electronics are two wellknown IDMs.
The advantages of a vertically-integrated supply chain motivate large semiconductor companies to pursue an IDM model. By owning every stage of the process, production may be more efficient and cost-effective. IDMs are also not susceptible to shortages of production capacity imposed by external foundries, which have to allocate their finite manufacturing resources to their various clients.
Most importantly, the IDM model prevents the transfer of trade secrets to external parties. Fabless companies have to outsource the fabrication of their microchips to third-party foundries or IDMs. For that reason, there is potential for commercially valuable chip-design information to be leaked out.
Apple was one company which moved gradually away from competitor Samsung Electronics as its chip manufacturer and outsourced the production of its chips to TSMC.
However, doubt remains over the economic feasibility of the IDM model today. In a mature semiconductor industry where product complexity is high, it is impractical and costly for one company to handle all the processes.
After suffering multiple setbacks in its manufacturing process, Intel’s share price plummeted in 2020 due to delays in the launch of its next-generation 7nm chips. Rival chipmakers, which rely on external foundries, had already forged ahead of the chip race with their 7nm chips and production of 5nm chips in late 2020.
These technological hurdles and the costs involved for IDMs have led to a restructuring of the industry value chain. Consequently, the fabless-foundry model was found to offer flexibility for semiconductor companies to focus on their individual competencies while tapping the expertise of their strategic partners.
Possible 5G growth driver
The semiconductor industry is highly cyclical, based on the economics of derived demand. Semiconductor companies’ performances are highly dependent on end-market demand for chip-based products like person
al computers, smartphones, electric vehicles etc.
Nonetheless, there are several emerging structural trends that could provide the next lap of growth for the industry. Structural trends tend to be longer term and can be significantly more impactful than cyclical trends.
One of the main technological innovations that could spur the semiconductor sector to greater heights is the development of 5G. This is the fifth-generation mobile network and planned successor to 4G networks that currently provide connectivity to most mobile devices. The technology is meant to deliver higher data speeds, ultra-low latency and better reliability for users.
Moreover, 5G is designed for forward compatibility. It has the ability to support future services that are unknown today. It is estimated that 5G’s full economic effects will be felt across the globe by 2035. It could purportedly support up to US$13.2 trillion worth of global economic output.
For semiconductor companies, 5G provides plenty of business opportunities by enabling a wide range of new industries and companies to use semiconductor technology in their products and services. Generally, 5G is used for three main types of connected services: enhanced mobile broadband; mission-critical communications; and IoT. 1. Enhanced mobile broadband In addition to hardware improvements, 5G can usher in a new generation of mobile apps with new features made possible by the improved network technology.
Semiconductor companies can expect to see a surge in demand for 5G handsets and products — potentially increasing 5G revenue from near zero in 2018 to US$31.5 billion in 2023.
2. Mission-critical communications Current 4G network technologies are too unreliable for mission-critical applications. 5G’s extreme reliability and ultra-low latency promise to unlock vast new applications and use cases that could transform industries. Potential applications include the remote control of critical infrastructure, automotives and healthcare services.
Automotive applications and hardware, which utilise 5G and semiconductor technologies, are predicted to have a compound annual growth rate of 285% between 2021 and 2023.
3. Internet of Things (IoT)
The smartphone market was a major growth propeller for the semiconductor industry in recent years. However, with at least 80% smartphone penetration rates in both developed and developing nations, their growth rate might be tapering off.
Semiconductor firms must probe for new revenue sources and the IoT industry represents a major growth opportunity. This is evident from IoT products like smartwatches and smart TVs becoming mainstream among the global populace.
5G technology helps enable the expansion of the IoT industry by facilitating the development of new IoT products. These range from medical-monitoring systems to automatic sensors for self-driving cars. As new IoT devices are diffused to the market, the demand for semiconductor chips will proliferate.
According to the McKinsey Global Institute, the IoT industry could generate US$4 trillion to US$11 trillion in value globally for both consumer and business-to-business applications in 2025.
Exchange traded funds
Due to the cyclical nature of the semiconductor industry, the share prices of semiconductor companies tend to experience big swings in either direction, based on market and industry-specific conditions.
Coupled with the extraordinary pace of technological advancements, laggard semiconductor firms are often severely punished for their innovation failures and inventory obsolescence.
Rather than trying to time entry or pick winning companies, semiconductor-themed ETFs are convenient investment vehicles for investors to partake in the long-term growth potential of the sector. They provide exposure to a basket of companies across the entire value chain, which reduces the volatility and concentration risks of the investment portfolios.
No let-up
Semiconductors are the basic building blocks of modern computing. The industry has fabricated multiple generations of microchips for the past 60 years.
Rapid technological advancements are expected to unleash an onslaught of demand for semiconductor chips. This disruptive age confers unprecedented opportunities as well as challenges for semiconductor firms to develop innovative products and reconfigure their value chain to thrive in a highly competitive business environment.
Dependency on electronic computing devices is expected to create a multitude of tailwinds for the semiconductor industry, as consumption trends gain momentum in our digital society. E
