IC Industry at Heart of Possible China Takeover of Taiwan

Article By : IC Insights

Combined, China and Taiwan would hold about 37% of global IC capacity, almost 3x that of North America.

Healthy future global economic growth is increasingly dependent upon the continued introduction of advanced electronic systems. The critical components within these systems are integrated circuits (ICs), without which, advanced electronic systems cannot be produced, according to IC Insights, in its upcoming October Update to The McClean Report.

The ongoing trade conflict between the U.S. and China has intensified over the past couple of years. Crippling trade sanctions, especially with regard to IC technology, that the U.S. has imposed on Huawei, China’s largest electronics company, and to a lesser extent on SMIC, China’s largest indigenous IC foundry, has, in IC Insights’ opinion, caused China to question how it will be able compete in the future IC and electronics industries. It is increasingly apparent that China’s answer to that question centers on its reunification with Taiwan.

Just how important is the small island nation of 24 million people to the IC industry? Consider the following excerpts from IC Insights’ Global Wafer Capacity 2021-2025 Report and the 2021 McClean Report:

  • As of December 2020, Taiwan held the largest share of IC industry capacity of any country or region in the world. Moreover, if combined, the share of IC capacity within the borders of China and Taiwan would represent about 37% of global IC capacity, about 3x the amount of IC capacity located in North America.

  • Led by TSMC, Taiwan by far holds the largest share of leading-edge (i.e., <10nm) IC capacity (63%) of any country in the world (Figure 1).  South Korea, represented by Samsung, holds the remaining 37%.

  • Taiwanese companies hold almost 90% of Taiwan’s total IC capacity. The only non-Taiwanese IC fabs located in Taiwan are a small 150mm fab owned by U.S.-based Diodes and two advanced 300mm DRAM fabs owned by Micron (Fab 11 in Taoyuan with a capacity of 108K wafers per month and Fab 16 in Taichung with a capacity of 100K wafers per month).

  • Taiwan holds 22% of the world’s 300mm IC capacity, second only to South Korea, which holds a 25% share. In contrast, North America possesses only an 11% share of global 300mm IC capacity.

  • About 80% of Taiwan’s total IC capacity is dedicated to foundry production. Moreover, Taiwan’s pure-play foundries (i.e., TSMC, UMC, Powerchip, Vanguard, etc.) are forecast to represent almost 80% of the total worldwide pure-play foundry market in 2021.

The bottom line is that, currently, there is no more important base of IC capacity and production than Taiwan. Moreover, China has a huge problem with its inability to produce leading-edge IC devices for its future electronic system needs—a problem that it believes can be solved through reunification with Taiwan by whatever means necessary.

While the Taiwanese economy would crater if China attempted a military takeover of the island nation, China’s economy would also suffer greatly. The question is whether China is willing to accept relatively short-term economic pain for the long term benefit of having the largest amount of the world’s leading-edge IC production capacity under its control for many years to come.

    When (not if) China invades Taiwan, their allies (US mainly) will be in a non-nuclear shooting war with China over it even for a brief time. They will be able to keep Taiwan, only due to their close location to China. However, there will be a devastatingly high price to pay in mainland China for their aggression and there will be a worldwide fast decoupling of the world economy (lead by the USA and the UN) from China as punishment over a very long time frame. China will be relegated back to a third world economy under their current dictator all while the rest of the world replaces them with India and strong local production of goods which don’t have the supply chain issues seen currently. There will be NO long term benefit for China or sadly for their repressed people (then including the brave Taiwanese people). The world learned (and will have to relearn apparently) that just like with Nazi Germany prior to WW2, naked aggression has to be swiftly dealt with or it will spread like the cancer it is. This fast coming failure is all on the dictatorship of China’s CCP and history will see them in the same light as Hitler and the Nazi party.
