Is the merger between NAND flash memory chipmakers Kioxia and Western Digital (WD) , which was expected to be finalized this month, facing a twist? According to media reports, South Korean memory giant SK Hynix is opposing this merger and is considering a collaboration with Japan’s SoftBank to invest in Kioxia.

As reported by Yomiuri Shimbun on the 18th, insiders reveal that the merger negotiations between Kioxia and WD might be at an impasse. Although both sides aimed to reach a merger agreement this month, SK Hynix, which plans to indirectly invest in Kioxia, doesn’t concur with the merger. In anticipation of negotiations collapsing, SK Hynix considers partnering with SoftBank to invest in Kioxia.

Kioxia, a spin-off from Toshiba’s memory business, was sold in 2018 to a Bain-Capital-lead consortium, including SK Hynix, and Hoya. At that time, regulations stipulated that the largest shareholder, Bain, must secure the consent of contributors like SK Hynix to promote this merger. It’s reported that SK Hynix is apprehensive that WD’s dominance will increase in this merger.

Reports suggest that SoftBank is currently bolstering its AI-related ventures. Therefore, by investing and enhancing relationships, SoftBank may secure a stable memory supply from Kioxia and SK Hynix.

Throne Shift for memory business? Mergers May Reshape Rankings

Nikkei reported on the 17th that SK Hynix does not approve of the Kioxia and WD merger. At this stage, SoftBank is not directly involved in the merger talks between Kioxia and WD. Kioxia and WD aim to secure a financing agreement with financial institutions this week to facilitate the merger. However, the lack of consent from SK Hynix may impact negotiations with financial institutions.

The report points out that in the NAND flash market, SK Hynix is the world’s second-largest manufacturer, trailing only Samsung. If Kioxia, the world’s third-largest manufacturer, and WD, the fourth-largest, were to merge, they would nearly match Samsung’s scale. This would create a significant gap between SK Hynix, which holds the third position, and raise concerns for SK Hynix.

Toshiba, currently holding approximately 40% of Kioxia, will also become a shareholder in the holding company, with Kioxia’s President, Nobuo Hayasaka, assuming the role of President for the holding company. Additionally, Kioxia will have the majority of seats on the board, granting substantial operational authority

According to data from TrendForce, In Q2 2023, Samsung leads the NAND memory market with 31.1% market share, while Kioxia holds 19.6%, and Western Digital has 14.7%. After the Kioxia-WD merger, their combined market share could exceed 34.3%, establishing them as the dominant force in the NAND memory market.

According to UDN News, Taiwan’s semiconductor foundry, Powerchip Semiconductor Manufacturing Corporation (PSMC), is planning to establish a 12-inch wafer plant in Japan, with Mie Prefecture emerging as a probable location. This facility will be part of a burgeoning semiconductor hub that links up with the thriving industrial city of Nagoya and UMC’s Japanese plant, pending the approval of Japanese government subsidies. PSMC would be the second Taiwanese semiconductor giant to set up shop in Japan after this move, expanding its global presence.

PSMC has yet to officially comment on its investment in Japan or the specific site for the plant. Market observers note that PSMC’s Chairman, Frank Huang, has a track record of close collaboration with Japanese firms. From early partnerships with Elpida in producing DRAM to later contract manufacturing of ICs for Renesas, PSMC’s order books are expected to be promising in Japan.

In July of this year, PSMC announced a partnership with the Japanese financial group SBI Holdings to establish a 12-inch wafer foundry within Japan and seek official Japanese subsidies.

PSMC envisions that the Japanese foundry will utilize 22/28-nanometer manufacturing processes and incorporate advanced Wafer on Wafer stacking technology to meet the demands of the AI market. Recent reports suggest that the Japanese government has granted substantial subsidies, around 140 billion yen, for the PSMC-SBI collaboration in Japan, although PSMC refrains from commenting on this matter.

Recent reports indicate that the location of PSMC’s new facility in collaboration with SBI is likely to be in Mie Prefecture. This choice is supported by two key factors. Firstly, it’s in close proximity to the bustling industrial hub of Nagoya, offering logistical advantages for both raw materials and wafer exports. Additionally, UMC acquired Fujitsu’s 12-inch wafer plant in Kuwana City, Mie Prefecture, showcasing regional wafer expertise. This choice benefits from the industrial cluster, streamlining recruitment and material logistics for construction and production.

It is understood that PSMC’s collaboration with SBI to establish a plant in Japan will follow a similar joint-venture mode like Nexchip Semiconductor Corporation in China several years ago. PSMC will provide its expertise in constructing the plants and managing the production lines. Once everything is up and running smoothly, they will gradually reduce their involvement and may adopt a shareholding model for the Japanese wafer plant.

TSMC is in the process of constructing a semiconductor factory in Kikuyo-cho, Kumamoto Prefecture, Kyushu, Japan (referred to as Plant 1). Production is expected to commence in December 2024. Besides this facility, TSMC has shown interest in establishing a second plant in Japan (referred to as Plant 2). According to Japanese reports, the government is considering providing TSMC with a substantial subsidy of up to 900 billion Japanese Yen for Plant 2.

On October 4, during the Public-Private Partnership Forum on Increasing Domestic Investment led by Japanese Prime Minister Fumio Kishida, plans were announced for economic measures to be finalized within October. The Ministry of Economy, Trade, and Industry of Japan (METI) will request a budget of 3.4 trillion Japanese Yen to establish three funds supporting semiconductor production and research and development. These funds are the ” Research and Development Project of the Enhanced Infrastructures for Post-5G Information and Communication Systems,” the “Specified Semiconductor Funding Program,” and the “Ensuring Stable Supply Support Fund.”

As reported by Asahi Shimbun, sources suggest that the METI deems it necessary to grant 900 billion Japanese Yen in subsidies for TSMC’s proposed Plant 2, nearly 600 billion Japanese Yen for the “Rapidus” national team aiming to produce next-gen semiconductor chips domestically, and 700 billion Japanese Yen for traditional chips like Sony CMOS image sensors.

The Japanese government will allocate the required funds for these economic measures in the 2023 fiscal year supplementary budget. If the METI’s budget request is approved, the budget for semiconductor-elated activities in the 2023 fiscal year supplementary budget (3.4 trillion Japanese Yen) will be 2.6 times higher than that in the 2022 fiscal year supplementary budget (1.3 trillion Japanese Yen).

The Kishida administration also announced plans to ease land restrictions for crucial manufacturing facilities such as semiconductor plants during the forum. As early as December, local governments will be able to issue development permits for agricultural land, forests, and other areas.

Before that, local governments could only grant permits for industries related to food logistics, data centers, and plant facilities. Now, this is being expanded to include vital strategic materials. Furthermore, changing the land category from agricultural land often required approvals from multiple government departments, a process that could take more than a year. In the future, these procedures are expected to be shortened to around four months.
