The government and Taiwanese semiconductor companies should focus on enhancing local domestic supply chain resilience as geopolitical tensions and war in the Middle East pose a growing risk to chip production.
Semiconductors are a strategic resource due to the intensifying US-China technology race and global trade shocks, and Taiwanese semiconductor companies such as Taiwan Semiconductor Manufacturing Co (TSMC) and its suppliers — from clean room install services providers and raw material suppliers to semiconductor inspection services providers — are under pressure to set up production lines in Japan, the US or Europe to minimize the risk of supply disruption.
About 25 percent of SEMI Taiwan’s member corporations said they are planning to set up new operations or manufacturing factories in the US in response to requests from customers amid geopolitical conflicts, a survey showed.
TSMC has committed to investing US$165 billion to build advanced chip fabrication plants in the US. Its local manufacturing facilities and clean room builder, United Integrated Services Co, special chemicals supplier Chang Chun Petrochemical Co, and semiconductor inspection service provider Msscorps Co, as well as Rayzher Industrial Co, which specializes in installing mains systems and gas pipelines to transmit utilities for semiconductor manufacturers, have set up operations in Arizona, near TSMC’s fabs.
Other suppliers are still assessing the feasibility of following TSMC, balancing expensive labor costs and high factory construction costs against the potential returns.
The Iran war has become the newest challenge for semiconductor companies, as spikes in transportation costs drive up operational costs, a secondary effect of the closure of the Strait of Hormuz.
Some suppliers of chemical filters and other components said that costs have increased more than 100 percent due to disrupted shipping, spiking fuel prices and growing maritime insurance premiums.
Many semiconductor companies believe that supply chain disruption is a distant headache, with significantly stronger supply chain resilience and countermeasures put in place after the COVID-19 pandemic and Russia’s invasion of Ukraine.
The Ukraine invasion halted neon output for one of the world’s largest producers of the noble gas in 2021, creating a bottleneck for chip production. Ukraine’s production made up about 50 to 70 percent of global semiconductor-grade neon.
Taiwan’s semiconductor companies have learned from the two shocks to the global order at the start of this decade, significantly increasing their safety margins of key materials and chemicals to one to three months, creating a buffer against supply uncertainties.
Taiwan’s extensive semiconductor ecosystem could help protect it from short-term external shocks, but some key semiconductor materials, such as some gases and photoresistant materials, have shelf lives of only four to six months.
The war against Iran could affect the industry more drastically if the conflict drags on for six months or more or the scope of the conflict broadens, although US President Donald Trump said he wants to end the war soon.
Industry experts urged companies to adopt multiple procurement sources and look to sources beyond the Middle East.
The supply of helium, used in semiconductor production, could become a choke point after Qatar shut down its liquefied natural gas (LNG) production and helium output following strikes on its infrastructure.
While the Ministry of Economic Affairs is confident that LNG supplies are adequate, supply chain resilience must cover many bases.
The ministry last week said that the supply of LNG and helium in Taiwan is sufficient, while it has options to pivot to sources such as Australia and the US.
On Monday, it said that LNG supply would be stable through the end of May.
In response to the geopolitical tensions in the Middle East, CPC Corp, Taiwan has expanded its procurement of gas to sources outside the Middle East to ensure sufficient supplies, the ministry said.
“There is absolutely no natural gas shortage crisis as reported by foreign media,” it said.
However, as peace talks crawl along, semiconductor companies should shift their efforts to improve domestic supply chain resilience and avoid supply constraints of all of their critical materials from becoming a bottleneck for chip production.
In the event of a war with China, Taiwan has some surprisingly tough defenses that could make it as difficult to tackle as a porcupine: A shoreline dotted with swamps, rocks and concrete barriers; conscription for all adult men; highways and airports that are built to double as hardened combat facilities. This porcupine has a soft underbelly, though, and the war in Iran is exposing it: energy. About 39,000 ships dock at Taiwan’s ports each year, more than the 30,000 that transit the Strait of Hormuz. About one-fifth of their inbound tonnage is coal, oil, refined fuels and liquefied natural gas (LNG),
On Monday, the day before Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) departed on her visit to China, the party released a promotional video titled “Only with peace can we ‘lie flat’” to highlight its desire to have peace across the Taiwan Strait. However, its use of the expression “lie flat” (tang ping, 躺平) drew sarcastic comments, with critics saying it sounded as if the party was “bowing down” to the Chinese Communist Party (CCP). Amid the controversy over the opposition parties blocking proposed defense budgets, Cheng departed for China after receiving an invitation from the CCP, with a meeting with
To counter the CCP’s escalating threats, Taiwan must build a national consensus and demonstrate the capability and the will to fight. The Chinese Communist Party (CCP) often leans on a seductive mantra to soften its threats, such as “Chinese do not kill Chinese.” The slogan is designed to frame territorial conquest (annexation) as a domestic family matter. A look at the historical ledger reveals a different truth. For the CCP, being labeled “family” has never been a guarantee of safety; it has been the primary prerequisite for state-sanctioned slaughter. From the forced starvation of 150,000 civilians at the Siege of Changchun
The two major opposition parties, the Chinese Nationalist Party (KMT) and the Taiwan People’s Party (TPP), jointly announced on Tuesday last week that former TPP lawmaker Chang Chi-kai (張啟楷) would be their joint candidate for Chiayi mayor, following polling conducted earlier this month. It is the first case of blue-white (KMT-TPP) cooperation in selecting a joint candidate under an agreement signed by their chairpersons last month. KMT and TPP supporters have blamed their 2024 presidential election loss on failing to decide on a joint candidate, which ended in a dramatic breakdown with participants pointing fingers, calling polls unfair, sobbing and walking
