Japanese auto elements maker Denso stated late final month that it will construct a significant manufacturing plant for energy chips with Taiwanese foundry UMC, a transfer that highlights the rising demand for these specialised semiconductors utilized in all the things from electrical automobiles to trains to wind generators.
However the announcement can be one other signal of what Japanese authorities and trade specialists say is the home chip trade’s biggest weak point: fragmentation.
Denso selected to associate with the native unit of a Taiwanese chip producer, whereas its 4 home friends are additionally investing in their very own manufacturing vegetation.
Energy chips are a kind of semiconductor used for regulating electrical energy flows, and are important for all the things from electrical automobiles and air conditioners to information centre servers and manufacturing unit robots.
This section accounted for near 10 per cent of the $555bn international chip trade in 2021, and demand is anticipated to develop consistent with the broader semiconductor market, in response to World Semiconductor Commerce Statistics. “They’re indispensable units for the worldwide transition from fossil fuels,” stated Hideki Wakabayashi, a professor on the Tokyo College of Science and a member of an advisory panel at Japan’s Ministry of Economic system, Commerce and Business (Meti).

The query for Japan’s chipmakers is whether or not they are going to have the ability to maintain on to their area of interest. The world’s greatest energy chipmaker — Germany’s Infineon Applied sciences — boasts a 21 per cent international market share, equal to Japan’s high 5 producers mixed.
Specialists say the comparatively small scale of Japanese chipmakers makes it troublesome for them to scale up manufacturing and advertising and marketing. Japanese producers are additionally cautious about making massive investments, lest their friends do the identical and an oversupply outcomes.
Consolidation is required, specialists say, earlier than the nation’s share within the international market slips additional — Japan misplaced 1.2 proportion factors from 2020 to 2021.
Some are trying to show phrases into motion.
Fumiaki Sato, co-founder of Sangyo Sosei Advisory, a boutique funding banking firm, goals to determine a chip foundry that would offer manufacturing companies for any and all of Japan’s energy chipmakers. The thought is to create an influence semiconductor equal of Taiwan Semiconductor Manufacturing Firm (TSMC), the worlds largest contract chipmaker, stated Sato, a former vice-chair at Merrill Lynch Japan.
“Every firm invests in its manufacturing capability. In the event that they want extra, they may come to us,” Sato advised Nikkei Asia. Constructing a chip manufacturing unit prices as much as ¥100bn ($765mn), he stated. “Corporations see it as a dangerous enterprise, even at a time when demand is broadly anticipated to develop. There’s at all times a danger of oversupply.”
Sato is buying an outdated chip plant in Niigata, central Japan, from Onsemi of the US, and his initiative was awarded a subsidy from Meti final yr. However thus far, the plan has but to maneuver ahead.
Sato cited challenges reminiscent of securing extra funding and potential clients.
One issue that has held again enlargement of capability is the character of energy semiconductors themselves. They’re designed to deal with high-voltage tools, and are sometimes constructed to particular person product specs relatively than mass-produced.
However the trade may endure a radical shift as mass manufacturing of electrical automobiles begins, resulting in requires cheaper standardised chips, stated Masao Taguchi, a former head of Fujitsu’s semiconductor enterprise. “Energy semiconductors may grow to be extra standardised, leading to firms able to scaling up manufacturing dominating the market,” he stated. “That’s what has occurred within the DRam market,” he added, referring to how Japanese chipmakers misplaced out to South Korean rivals within the reminiscence chip market.
Infineon of Germany has pulled forward within the race for scale. It operates two massive fabrication vegetation for 300mm wafers, one in Dresden and the opposite in Villach, Austria. Denso’s facility will solely come on-line within the first half of subsequent yr.
Toshiba is constructing two 300mm manufacturing amenities, one scheduled for operation within the present fiscal yr and one other for fiscal 2024. Mitsubishi Electrical will begin mass-producing 300mm wafers solely in fiscal 2024.
Fuji Electrical, a key provider to Toyota and Honda, stated that it was not chasing market share and retains its capital funding beneath shut management. It stated it was getting ready to develop a 300mm facility however declined to elaborate on the timeframe.
An trade official stated that “consolidation is unlikely to happen until it turns into actually essential”.
Policymakers, in the meantime, are conserving an in depth eye on the state of affairs.
Meti reconvened its semiconductor trade technique panel on April 14 to debate, amongst different issues, a method for strengthening the facility semiconductor trade.
Demand for such semiconductors is anticipated to “develop quick” and “may outstrip provide”, stated Kazumi Nishikawa, director of METI’s IT trade division.
The ministry has lately offered subsidies to Japanese chipmakers to assist them improve their ageing vegetation, however Nishikawa stated this was a short-term repair, not a long-term answer. “As a high producer of energy semiconductors, Japan has a duty to the remainder of the world for provide,” he stated.
The federal government is anticipated to spell out concrete assist measures for the trade as soon as a invoice is handed to beef up the nation’s financial safety, he stated. These measures are anticipated to be a part of subsequent yr’s finances.
Meti scored a victory final yr when it helped persuade TSMC to construct a chip plant in Kumamoto, southern Japan, however the ministry stated there was extra to be executed. “We’ve managed to get to the beginning line,” Nishikawa stated of the TSMC deal. “Progress within the chip trade is quick. Pause your efforts, and also you’ll fall behind.”
One of many greatest duties for the trade shall be tackling Japan’s keiretsu system, by which firms type shut affiliations and focus extra on serving one another than the broader market. Breaking down this method shall be essential to reorganising Japan’s fragmented chip trade.
Taguchi, the previous Fujitsu government, sees a pacesetter in Toshiba, which created the world’s second-largest flash reminiscence maker, Kioxia. “Toshiba has excessive international recognition. It may possibly grow to be a rallying level for the Japanese semiconductor trade,” he stated.
Wakabayashi, the Tokyo College of Science professor and member of the Meti technique panel, additionally pressured the significance of being aggressive on a world scale.
“Main clients of energy semiconductors are prone to be international automotive suppliers — Denso, Bosch and Continental,” Wakabayashi stated. “Denso is maintaining a superb struggle, however the others are Europeans.”
