Micron, the fifth largest market share in the global NAND flash market, is aiming to acquire Kioxia, Japan, which ranks second. Except for No. 1 Samsung Electronics, companies of similar size are trying to gain weight through a joint venture. As of the fourth quarter of last year, if Micron, with 11.2% of NAND flash market share, possesses 19.5% Kioxia, it will pursue Samsung Electronics with 32.9% market share.

Western Digital, the third place in the NAND market along with Micron, is also considering acquiring Kioxia. If Western Digital takes Kioxia, the combined market share will outperform Samsung Electronics. The industry believes that there is a possibility that Micron and Western Digital will join forces with the recent trend of strengthening the semiconductor infrastructure capabilities of the United States. It is predicted that the competition for semiconductor supremacy from the US began in earnest, in line with last month’s decision to build two semiconductor factories in Arizona by spending 20 billion dollars (about 22 trillion won) by Intel.

According to the semiconductor industry on the 5th, Micron has won two world’s first titles in the last six months. In November of last year, it announced that it would develop the world’s first 176-layer NAND flash and start supplying it to customers. In January, it was also the world’s first fourth-generation (1a) 10 nanometer (nm·1 nanometer is 1 billionth of a meter) DRAM. Announced that it has succeeded in mass production.

Previously, Samsung Electronics took the world’s first title of the 1st~3rd generation (1x·1y·1z) 10-nano DRAM. In addition, SK Hynix has developed a 128-layer 4D NAND for the first time in the world, enhancing technological competitiveness in this area. However, as Micron sweeps away both the development and mass production of the 4th generation DRAM and 176-layer NAND, which are considered the next generation, the two companies were hurt by their pride. In the industry, Micron’s technological prowess is considered to be more than a year behind Samsung Electronics and SK Hynix.

The U.S. and the European Union (EU) recently declared “semiconductor self-reliance” due to the shortage of semiconductor supply that has recently swelled around the world, and decided to increase support for their own companies. In this trend, the successive technological overtakings of latecomers are threatening the status of Korean semiconductors, which were proud to be the number one in memory semiconductors.

The Joe Biden administration recently unveiled a $2.5 trillion (about 2540 trillion won) infrastructure plan. Of this, 50 billion dollars (about 5.6 trillion won) is the share of semiconductors. It is the sketch of the Biden administration that it is determined that the domestic ecosystem has collapsed due to being pushed by Korea and Taiwan, and that it will reinvigorate the semiconductor industry.

Previously, Intel’s initiative to invest in new factories and foundries (consignment production of semiconductors), but Micron and Western Digital’s announcement of acquiring Kioxia seems to be in line with the US government. In fact, Intel even made a support statement shortly after the Biden administration’s announcement. Pet Gelsinger, Intel’s CEO, said, “The Biden administration is helping a lot (in relation to plant expansion and investment).”

On the same day, the Korean government held the’Innovative Growth Big 3 Promotion Meeting’ and announced’plans to develop next-generation power semiconductor technology and expand production capabilities’. It is believed that each country’s war for hegemony in semiconductors has begun, and it is intended to preoccupy future foods by supporting domestic companies and industries. However, the government was not concerned about the specific size of the investment. An industry insider said, “Companies know better than the government which semiconductor field will receive attention in the future.” “It’s a support plan, but this announcement only presented a bunch of blueprints, so I didn’t feel interested.”

There are concerns that domestic semiconductor companies will be isolated while US semiconductor companies, which have been supported by the government, are in earnest and are trying to increase their competitiveness. In particular, Samsung Electronics, which is targeting both memory and system (non-memory) semiconductors at the same time, is losing focus because there is a high possibility that investment will be diversified only by the ability of the company. According to a report from the National Federation of Businessmen last year, in the case of SMIC in China, government subsidies were 6.6% of sales and Micron in the US was 3.3%, whereas Samsung Electronics was only 0.8%, and SK Hynix was less than 0.5%.

Some have come up with the prospect that Korean companies, which are the world’s leading companies, may go abroad by others. It is expected that an attempt will be made to attract factories of domestic companies with technological competitiveness to their countries. The Center for Strategic International Research (CSIS), known as a representative think tank in the United States, said, “The US government should support not only domestic companies, but also support Korean and Taiwanese companies with strengths in the semiconductor industry to set up factories in the United States.” He also released a report of. In addition, senior security and economy officials at the White House will discuss the problem of semiconductor supply shortages with officials from semiconductor and automobile companies on the 12th (local time), and Samsung Electronics will attend this event.

Taiwan’s TSMC, the No. 1 foundry company, announced a large-scale investment plan, including the expansion of factories in the United States this year, which is reportedly supported by the support of the US governments. Samsung Electronics is also looking for investments for the expansion of a new plant worth 19 trillion won, and Texas, Arizona, and New York are currently competing. An official from Samsung Electronics said, “Currently, the expansion of the semiconductor plant is in negotiations with each state in the United States (for support plans, etc.),” ​​he said.
