UKRAINE WAR COULD HURT SUPPLIES OF NEON, PALLADIUM NEEDED FOR CHIPS

By Matt Hamblen Feb 24, 2022 08:37pm

Lasers used in the complex chipmaking process rely on high-grade neon, which
primarily comes from Ukraine, now under attack from Russia. Shortages of neon,
palladium and C4F6 could result from the conflict, coming atop chip shortages
for the past 17 months. (Getty Images)

Another chip supply chain crisis could be in store due to the emerging
Russia-Ukraine conflict. Russia invaded Ukraine on Thursday, firing missiles
into military installations and advancing tanks and troops into several large
cities throughout the country of 40 million people.






Ukraine makes more than 90% of the high-grade neon in gas-phase lasers used to
make chips produced by U.S. semiconductor companies. The gas is a biproduct of
Russian steel manufacturing which is purified in Ukraine, said market research
company Techcet. Neon prices soared during the Russia-Ukraine conflict in 2014.



Meanwhile, Russia provides a third of the palladium metal used in sensors and
memory products produced by U.S. companies. Russia is also a “crucial” source of
C4F6 (hexafluorocyclobutene), which several U.S. suppliers buy and purify for
advanced node logic device etching and advanced lithography processes for chip
production, Techcet wrote in advance of the invasion as Russia build up troops
along the border of Ukraine in recent weeks.




 It isn’t clear whether these commodities could be disrupted by the conflict,
although chipmakers are following the unfolding crisis carefully.

Both potential supply shortages come atop more than a year of global chips
shortages, pushing U.S. companies, especially carmakers, to scramble to build up
chip reserves or set up exclusive deals with chipmakers to serve their needs.

The availability of neon and palladium was already tight, but the conflict could
push up prices, which could in turn result in higher chip prices.



Techcet CEO Lita Shon-Roy said if the conflict escalates and if the U.S. imposes
more sanctions on Russia, then Russia could retaliate by withholding critical
materials needed for U.S. chip production. “Because the conflict may impede
exports from Ukraine, neon supply would be immediately impacted,” Shon-Roy said.
C4F6 and Palladium exports that come directly from Russia could also be withheld
as leverage against trade sanctions.

“We hope it will not come to that; however, if the current situation escalates,
U.S. chipmakers may suffer material supply interruptions,” Shon-Roy said.

Micron Technology, a big memory chipmaker, called the potential disruption of
materials “concerning for the semiconductor industry,” according to a statement,
adding it has diversified supply sources.

The Semiconductor Industry Association, representing nearly all U.S.
semiconductor companies, said in a statement that the industry has a diverse set
of suppliers or key materials and gases, "so we do believe are immediate supply
disruption risks." 



A large supplier to chipmakers, ASML, said it has been seeking alternative
sources for neon it uses in its factories, according to Reuters. ASML had 85% of
its sales in Asia in 2021, a continent that produces the majority of all the
world’s chips. Intel, Samsung and TSMC all make chips and are large ASML
customers[MH1] .

Reuters also reported that SK Hynix, a memory chipmaker in South Korea, reported
it had a good supply of chip materials, adding “there’s no need to worry.” Intel
told Reuters it did not anticipate any impact.
