Reference excerpt

The semiconductor industry is the aggregate of companies engaged in the design and fabrication of semiconductors and semiconductor devices, such as transistors and integrated circuits. Its roots can be traced to the invention of the transistor by Shockley, Brattain, and Bardeen at Bell Labs in 1948. Bell Labs licensed the technology for $25,000, and soon many companies, including Motorola (1952), Shockley Semiconductor (1955), Sylvania, Centralab, Fairchild Semiconductor and Texas Instruments were making transistors. In 1958 Jack Kilby of Texas Instruments and Robert Noyce of Fairchild independently invented the Integrated Circuit, a method of producing multiple transistors on a single "chip" of Semiconductor material. This kicked off a number of rapid advances in fabrication technology leading to the exponential growth in semiconductor device production, known as Moore's law that has persisted over the past six or so decades. The industry's annual semiconductor sales revenue has since grown to over $481 billion, as of 2018. In 2010, the semiconductor industry had the highest intensity of Research & Development in the EU and ranked second after Biotechnology in the EU, United States and Japan combined. The semiconductor industry is in turn the driving force behind the wider electronics industry, with annual power electronics sales of £135 billion ($216 billion) as of 2011, annual consumer electronics sales expected to reach $2.9 trillion by 2020, tech industry sales expected to reach $5 trillion in 2019, and e-commerce with over $29 trillion in 2017. In 2019, 32.4% of the semiconductor market segment was for networks and communications devices. In 2025, the sales of semiconductors reached a record $791.7 billion, up 25.6%, driven largely by demand for artificial intelligence hardware, according to the Semiconductor Industry Association. Sales of logic products were the largest product category, totaling $301.9 billion, followed by memory products at $223.1 billion. Regionally, annual sales grew most in Asia Pacific (45.0%), followed by the Americas (30.5%), China (17.3%), and Europe (6.3%), while sales in Japan declined 4.7%. The semiconductor industry is projected to reach roughly $1 trillion in sales in 2026.

Industry structure The global semiconductor industry is dominated by companies from the United States, Taiwan, South Korea, Japan and the Netherlands, with Israel and Germany having significant presence in the field.

Unique features of the industry include continuous growth but in a cyclical pattern with high market fluctuation over the short run. While the current 20-year annual average growth of the semiconductor industry is on the order of 13%, this has been accompanied by equally above-average market volatility, which can lead to significant if not dramatic cyclical swings. This has required the need for high degrees of flexibility and innovation in order to constantly adjust to the rapid pace of change in the market as many products embedding semiconductor devices often have a very short life cycle. At the same time, the rate of constant price-performance improvement in the semiconductor industry is staggering. As a consequence, changes in the semiconductor market not only occur extremely rapidly but also anticipate changes in industries evolving at a slower pace. The semiconductor industry is widely recognized as a key driver and technology enabler for the whole electronics value chain. Prior to the 1980s, the semiconductor industry was vertically integrated. Semiconductor companies both designed and manufactured chips in their own facilities. In many cases, this included inventing new processes, refining and purifying source chemicals and silicon wafers, and even manufacturing equipment, like furnaces, lithography tools and etchers. These companies also carried out the assembly and testing of their chips. Over time, many of these functions were outsourced, such that today semiconductor manufacturers rely on a complex supply chain to provide wafers, high-purity source chemicals, and processing equipment. Further, starting with LSI in 1969, the industry has seen the emergence of Fabless Semiconductor Companies that focus solely on chip design and rely on other companies to manufacture their designs. Initially, these other companies were integrated device manufacturers (IDMs), companies that also designed and manufactured their own products, and thus were often competitors of the Fabless companies. But, by the mid-1980's, TSMC and UMC emerged as foundries, specializing solely in the manufacture of other companies' designs. Today, much of the industry is based on the foundry model, which consists of semiconductor fabrication plants (foundries) and integrated circuit design operations, each belonging to separate companies or subsidiaries. Some companies, known as integrated device manufacturers, both design and manufacture semiconductors. The foundry model has resulted in consolidation among foundries. As of 2021, only three firms are able to manufacture the most advanced semiconductors: TSMC of Taiwan, Samsung of South Korea, and Intel of the United States. Part of this is due to the high capital costs of building foundries. TSMC's latest factory, capable of fabricating 3 nm process semiconductors and completed in 2020, cost $19.5 billion. Intel is considering outsourcing some production to TSMC. It currently can only produce 10 nm semiconductors, while TSMC and Samsung can both produce 5 nm. GlobalFoundries, an American-headquartered firm, uses a 12 nm process for its most advanced chips due to the rapidly increasing development costs of smaller process nodes.

Notes:

Pure-play foundries – They specialize in foundry services. They may or may not offer design services to third parties, as well as mask (photomask) making, semiconductor packaging and testing services, which can also be outsourced to other companies. An example is TSMC, which offers design, testing and packaging services, TCE photomasks, which offers only mask making services, and ChipMOS, which offers only packaging and testing services. IDMs (integrated device manufacturers) – They may or may not offer foundry services. Fabless suppliers – They do not offer foundry services. They may or may not offer design services to third parties.

Worked examples

Example 1 — a first encounter with Semiconductor industry

Start with the simplest possible case. Write down what Semiconductor industry claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Semiconductor industry before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Semiconductor industry ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Semiconductor industry

In research
Semiconductor industry appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Semiconductor industry in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Semiconductor industry is common in secondary-school and first-year university syllabi. It links to neighbouring topics Industries (economics), Semiconductor industry, so understanding it makes those chapters shorter.
In everyday life
Look for Semiconductor industry outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
