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
volatility. 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. ==Semiconductor sales==
