In the past two years, the semiconductor industry has experienced a market downturn, a recovery slower than expected, and a cash crunch. Major companies such as Intel, TSMC, and Samsung, while continuing to advance their expansion projects, have been constantly adjusting and slowing down the pace and schedule of their fab construction to better serve their long-term development goals. It’s found that seven fabs worldwide are projected to delay construction.

• Intel’s 1nm Chip Plant in Germany and Ohio Plant in the US Delay Construction

According to a report from global media outlet Volksstimme, the construction of Intel’s Fab 29.1 and Fab 29.2 near Magdeburg, Germany, has been postponed due to pending approval of EU subsidies and the need to remove and reuse black soil. The date of commencement has been pushed from summer 2024 to May 2025.

Earlier reports indicated that the construction of this chip planr was initially expected to begin in 1H23, but due to subsidy delays, construction was put off to summer 2024. Moreover, the topsoil at the construction site cannot be cleared until May 2025 at the earliest.

It is reported that Intel’s Fab 29.1 and Fab 29.2 were originally scheduled to start operations by late 2027 and were expected to employ advanced manufacturing processes, potentially Intel 14A (1.4nm) and Intel 10A (1nm) process nodes. However, Intel now estimates that it will take four to five years to build these two plants, and production is expected to commence between 2029 and 2030.

• Samsung’s Chip Plant in Pyeongtaek, South Korea and Fab in Taylor, US Delay Construction

In February 2024, Samsung revealed that it had partially halted the construction of its fifth semiconductor plant in Pyeongtaek, Gyeonggi Province. Samsung originally planned to build six semiconductor plants on an 855,000 square meter site in Pyeongtaek, creating the world’s largest semiconductor hub. Currently, the P1, P2, and P3 plants at the Pyeongtaek park house the most advanced DRAM, NAND flash memory, and foundry production lines, while the P4 and P5 plants are under construction.

Samsung stated that the halt was for further inspection. However, industry sources have revealed that Samsung’s adjustment of the new production lines for P4 and P5 fabs is to prioritize the construction of the PH2 production line at P4 fab. It is reported that P4 plant might build PH3 production line to produce high-end DRAM to meet market demands.

Besides, South Korean media Businesskorea also revealed Samsung has postponed the mass production timeline of the fab in Taylor, Texas, US from late 2024 to 2026, which is possibly due to a slowdown in the wafer foundry market growth, and the delay was attributed to U.S. government subsidies and issues related to the complexities in gaining permits.

• TSMC Postponed the Production of Two Plants in Arizona, US

On April 9, TSMC announced the plan to build a third fab in Arizona. Once completed, this fab will use 2nm process or even more advanced technologies to manufacture wafers for customers. With this addition, TSMC’s total capital expenditure in Phoenix, Arizona, will exceed USD 65 billion.

Meanwhile, TSMC disclosed that their first fab in Arizona will start production in 1H25, using 4nm process. The second fab, initially announced to use 3nm process, will also incorporate the more advanced 2nm process, with mass production set to begin in 2028. This fab was announced in December 2020, which was originally scheduled to start mass production using 3nm process in 2026, primarily, but the latest schedule represents a delay of nearly two years from the original one.

As to the third fab planned to set up in Arizona, TSMC has not yet disclosed the date for construction. However, they mentioned that it will use 2nm process or more advanced ones, with production expected to commence in the late 2030s.

• Wolfspeed’s 8-Inch SiC Fab might Delay Construction to 2025

Wolfspeed’s 8-inch SiC fab in Ensdorf, Saarland planned to invest about EUR 2.75 billion, but the construction has been postponed. The project has already secured subsidies of EUR 360 million from the German federal government and EUR155 million from the Saarland government. In addition, Wolfspeed is also seeking financial assistance from the European Chips Act. ZF will provide Wolfspeed with several hundred million dollars of financial investment in exchange for a minority stake in the plant.

Industry sources indicate that Wolfspeed aims to secure more funding before the groundbreaking ceremony. If it fails to gain financial assistance from the European Chips Act, the project is very likely to be delayed. The plant was initially scheduled to start construction in summer 2024, but Wolfspeed CEO Gregg Lowe revealed that it might now begin in 2025.

To capture the booming demand of AI processors, memory heavyweights have been aggressively expanding HBM (High Bandwidth Memory) capacity, as well as striving to improve its yield and competitiveness. The latest development would be Micron’s reported new plant in Hiroshima Prefecture, Japan.

The fab, targeting to produce chips and HBM as early as 2027, is reported to manufacture DRAM with the most advanced “1γ” (gamma; 11-12 nanometers) process, using extreme ultraviolet (EUV) lithography equipment in the meantime.

Why is HBM such a hot topic, and why is it so important?

HBM: Solution to High Performance Computing; Perfectly Fitted for AI Chips

By applying 3D stacking technology, which enables multiple layers of chips to be stacked on top of each other, HBM’s TSVs (through-silicon vias) process allows for more memory chips to be packed into a smaller space, thus shortening the distance data needs to travel. This makes HBM perfectly fitted to high-performance computing applications, which requires fast data speed. Additionally, replacing GDDR SDRAM or DDR SDRAM with HBM will help control energy consumption.

Thus, it would not be surprising that AMD, the GPU heavyweight, collaborated with memory leader SK hynix to develop HBM in 2013. In 2015, AMD launched the world’s first high-end consumer GPU with HBM, named Fiji. While in 2016, NVIDIA introduced P100, its first AI server GPU with HBM.

Entering the Era of HBM3e

Years after the first AI server GPU with HBM was launched, NVIDIA has now incorporated HBM3e (the 5^th generation HBM) in its Blackwell B100/ Hopper H200 models. The GPU giant’s GB200 and B100, which will also adopt HBM3e, are on the way, expected to be launched in 2H24.

The current HBM3 supply for NVIDIA’s H100 is primarily met by SK hynix. In March, it has reportedly started mass production of HBM3e, and secured the order to NVIDIA. In May, yield details regarding HBM3e have been revealed for the first time. According to Financial Times, SK hynix has achieved the target yield of nearly 80%.

On the other hand, Samsung made it into NVIDIA’s supply chain with its 1Znm HBM3 products in late 2023, while received AMD MI300 certification by 1Q24. In March, Korean media Alphabiz reported that Samsung may exclusively supply its 12-layer HBM3e to NVIDIA as early as September. However, rumors have it that it failed the test with NVIDIA, though Samsung denied the claims, noting that testing proceeds smoothly and as planned.

According to Korea Joongang Daily, Micron has roused itself to catch up in the heated competition of HBM3e. Following the mass production in February, it has recently secured an order from NVIDIA for H200.

Regarding the demand, TrendForce notes that HBM3e may become the market mainstream for 2024, which is expected to account for 35% of advanced process wafer input by the end of 2024.

HBM4 Coming Soon? Major Players Gear up for Rising Demand

As for the higher-spec HBM4, TrendForce expects its potential launch in 2026. With the push for higher computational performance, HBM4 is set to expand from the current 12-layer (12hi) to 16-layer (16hi) stacks. HBM4 12hi products are set for a 2026 launch, with 16hi in 2027.

The Big Three have all revealed product roadmaps for HBM4. SK hynix, according to reports from Wccftech and TheElec, stated to commence large-scale production of HBM4 in 2026. The chip will, reportedly, be the first chip from SK hynix made through its 10-nm class Gen 6 (1c) DRAM.

As the current market leader in HBM, SK hynix shows its ambition in capacity expansion as well as industrial collaboration. According to Nikkei News, it is considering expanding the investment to Japan and the US to increase HBM production and meet customer demand.

In April, it disclosed details regarding the collaboration with TSMC, of which SK hynix plans to adopt TSMC’s advanced logic process (possibly CoWoS) for HBM4’s base die so additional functionality can be packed into limited space.

Samsung, on the other hand, claimed to introduce HBM4 in 2025, according to Korea Economic Daily. The memory heavyweight stated at CES 2024 that its HBM chip production volume will increase 2.5 times compared to last year and is projected to double again next year. In order to embrace the booming demands, the company spent KRW 10.5 billion to acquire the plant and equipment of Samsung Display located in Tianan City, South Korea, for HBM capacity expansion. It also plans to invest KRW 700 billion to 1 trillion in building new packaging lines.

Meanwhile, Micron anticipates launching 12-layer and 16-layer HBM4 with capacities of 36GB to 48GB between 2026 and 2027. After 2028, HBM4e will be introduced, pushing the maximum bandwidth beyond 2+ TB/s and increasing stack capacity to 48GB to 64GB.

Look back at history. As the market demand for AI chips keeps its momentum, GPU companies tend to diversify their sources, while memory giants vie for their favor by improving yields and product competitiveness.

In the era of HBM3, the supply for NVIDIA’s H100 solution is primarily met by SK hynix at first. Afterwards, Samsung’s entry into NVIDIA’s supply chain with its 1Znm HBM3 products in late 2023, though initially minor, signifies its breakthrough in this segment. This trend of diversifying suppliers may continue in HBM4. Who would be able to claim the lion’s share in the next-gen HBM market? Time will tell sooner or later.

The global semiconductor supply chain may face disruption as the Samsung Electronics union announces its first-ever company strike on June 7. According to a report from BBC, approximately 28,000 union members, accounting for more than 20% of Samsung’s total workforce, are expected to participate. The union accuses the company of long-term neglect of employees’ and the union’s demands.

Samsung Electronics is a major subsidiary of the Samsung Group, primarily responsible for the design, production, and assembly of consumer electronics, semiconductors, and communication devices. In the wafer foundry sector, Samsung is a key competitor to TSMC, with the two giants vying for leadership in advanced manufacturing processes.

In addition to its impact on the foundry industry, Samsung is also one of the world’s largest smartphone manufacturers and a leader in memory production. It is among the few global companies capable of integrating advanced memory chips into generative artificial intelligence technology.

Samsung is now facing the impact of a strike, which could further affect the global semiconductor supply chain.

However, as per industry sources cited by TechNews, it’s suggested that the strike by the Samsung union is unlikely to impact plant operations significantly.

As the union announces the strike, there has also been a significant shake-up in the chip division’s leadership. Young Hyun Jun has been appointed as the new head of the Device Solutions (DS) division, responsible for leading the company’s semiconductor business.

Per a report from Reuters, a source has noted that since Samsung’s personnel changes typically occur at the beginning of the year, it is unusual to replace a high-ranking executive like this in the middle of the year.

According to a report on May 29th from The Korea Economic Daily, it has speculated that AMD is likely to become a customer of Samsung Electronics’ 3nm GAA process. Reportedly, during AMD CEO Lisa Su’s appearance at the 2024 ITF World, which was hosted by the Belgian microelectronics research center imec, Lisa Su revealed that AMD plans to use the 3nm GAA process for mass-producing next-generation chips.

As per the same report, Lisa Su stated that 3nm GAA transistors can enhance efficiency and performance, with improvements in packaging and interconnect technology. This will make AMD products more cost-effective and power-efficient. The report further addresses that Samsung is currently the only chip manufacturer with commercialized 3nm GAA process technology.

Samsung announced in June, 2022, that it has started initial production of its 3 nm process node applying Gate-All-Around (GAA) transistor architecture. It claims that compared to 5nm process, the first-generation 3nm process can reduce power consumption by up to 45%, improve performance by 23% and reduce area by 16% compared to 5nm, while the second-generation 3nm process is to reduce power consumption by up to 50%, improve performance by 30% and reduce area by 35%.

An industry source cited by the report indicated that Su’s remarks could be interpreted as AMD planning to officially collaborate with Samsung on 3nm technology. Reports suggest that AMD is preparing to partner with Samsung, as TSMC’s 3nm production capacity has been fully booked by customers like Apple and Qualcomm.

The collaboration between the two companies could be traced back to April this year, as per a report from Korean media outlet viva100, Samsung was said to had signed a new USD 3 billion agreement with processor giant AMD to supply HBM3e 12-layer DRAM for use in the Instinct MI350 series AI chips. Reportedly, Samsung also agreed to purchase AMD GPUs in exchange for HBM products, although details regarding the specific products and quantities involved remain unclear.

As reported by the South Korean tech media outlet TheElec, South Korean smartphone giant Samsung is said to be planning to increase the production of phones manufactured by joint development manufacturers (JDM) in China from 4.4 million to 6.7 million units this year. The increased output from its JDM partners indicates that outsourced orders will account for 25% of Samsung’s smartphone production target for the year.

Reportedly, its JDM partners typically handles the production of low-end smartphones, being responsible for design and component procurement while Samsung provides the brand. For the past couple of years, the company has used JDM partners like Wintech to reduce its production cost for smartphones.

Furthermore, collaborating with JDM partners also enables Samsung to leverage the local manufacturers’ expertise in understanding trends. For instance, with the assistance of JDM partnerships, the Galaxy C55 was optimized locally for the Chinese market.

The number of Samsung smartphones produced by these JDM partners has also been steadily increasing in recent years. Data indicates that in 2019, JDM-produced phones accounted for less than 7% of Samsung’s smartphone output, but this year, that proportion has risen to 25%.

Regarding the current smartphone market in China, the China Academy of Information and Communications Technology (CAICT) has released its April 2024 analysis of the Chinese mobile phone market, showing a year-on-year increase of 28.8% in mobile phone shipments to 24.071 million units during the period.

According to the data from CAICT, in terms of brands, local brands dominated with 85.5% of the shipments, approximately 20.576 million units, while overseas brands, including Apple, accounted for nearly 3.5 million units.
