According to the latest spot prices for memory from TrendForce, due to the Chinese New Year holiday, the spot market is experiencing a limited number of released quotes and very few transactions for DRAM. The trading momentum in the NAND Flash spot market has also not shown any improvement. Details are as follows:

DRAM Spot Market:

Chinese OEMs are winding down their operations due to the upcoming Lunar New Year holiday. As a result, the spot market is experiencing a limited number of released quotes and very few transactions. Sellers’ quotes continue to drive the spot price rally, but there is not much actual demand. Although DRAM suppliers are withholding the amount of products going into the spot market, this has a limited effect in terms of sustaining the rally. The average spot price of mainstream chips (i.e., DDR4 1Gx8 2666MT/s) rose by 0.52% from US$1.922 last week to US$1.932 this week.

NAND Flash Spot Market:

Transaction momentum is not yet revitalized from the spot market, with market activities carrying on from that of last week under the absence of buy orders for retail NAND Flash products. Module houses are currently hoping that promotions from Chinese New Year would amplify order dynamics, which are seemingly quite difficult for the time being. The 512Gb TLC wafer spot stayed flat this week at US$3.437.

Porsche’s Chief Financial Officer Lutz Meschke has stated in a media interview following the conclusion of the Macan EV unveiling on January 25, 2024, that Europe’s initial plan to ban the sale of new fuel cars by 2035 may be postponed, as reported by Bloomberg.

TrendForce’s Insights:

• Prolonging the Battle and Gradually Narrowing the Gap with Chinese Automakers through Trade Barriers

In March 2023, the European Union passed a ban on the sale of new petrol and diesel cars starting from 2035.

Due to opposition from Germany and Italy, after coordination, the European Union agreed not to ban models using synthetic fuels. Range anxiety of electric vehicles continue to affect the willingness of end consumers to purchase cars, becoming the biggest obstacle to the growth of electric vehicle sales.

Coupled with China’s electric vehicle market, which accounts for over 50% of global BEV sales, nurturing Chinese automakers led by BYD, who continuously lead in the technical level of the the battery system, the electric drive system, and the electronic control system compared to Europe, America, and Japan.

Not long ago, Tesla CEO Elon Musk stated that without trade barriers, Chinese automakers would destroy the vast majority of their competitors. Whether this statement is exaggerated or not, trade barriers currently serve as the most effective means for Europe and the United States to prevent the continued growth and expansion of Chinese automakers, as exemplified by the United States’ IRA legislation and the European Union’s anti-subsidy investigations.

Delaying the implementation of the ban on the sale of new fuel cars can synergize with trade barriers, allowing consumers to maintain distance from Chinese-made electric vehicles. This approach provides breathing space for European automakers and US and Japanese automakers in the fuel car market.

With the Dual Strategy of Western and Japanese Automakers, Taiwanese Manufacturers Need Greater Flexibility in Planning

Assuming the postponement of the ban on the sale of new fuel cars, automakers in Europe, the United States, and Japan may simultaneously pursue synthetic fuel technology based on traditional fuel car frameworks while continuing to develop electric vehicle technology.

However, this dual approach, which does not favor one technology over the other, is likely to affect the allocation of resources for electric vehicles. During the era of internal combustion engine vehicles, dominated by Western, Japanese automakers, and Tier 1 suppliers due to various constraints such as patents and technological barriers, it has been challenging for Taiwan to access system-level supply opportunities.

In the era of electric vehicles, Fukuta Elec & Mach Co.’s all-in-one electric drive and control system has entered Mazda’s range-extended electric vehicle supply chain, while Foxconn has launched an electric vehicle manufacturing platform to vie for opportunities in complete vehicle manufacturing from carmakers. Consequently, Taiwan is gradually moving from Tier 3 and Tier 2 to Tier 1.

If automakers in Europe, the United States, and Japan adopt a dual strategy, Taiwanese manufacturers’ opportunities in the electric vehicle field may face reduction or fiercer competition.

Apart from continuously strengthening relevant technologies in the electric vehicle domain, Taiwanese manufacturers also need to enhance the commonality and modularity of their product lines to adapt to the ever-changing industrial regulations under geopolitical shifts.

In late December 2023, reports surfaced indicating OpenAI CEO Sam Altman’s intention to raise funds to construct a semiconductor plant, ensuring a secure supply of AI chips.

According to a report from the Washington Post on January 24, 2024, Sam Altman has engaged with US congressional members to discuss the construction of the semiconductor plant, including considerations of timing and location, highlighting his increasingly fervent ambition to establish the facility.

TrendForce’s Insights:

• Rising AI Computing Demands Heighten Sam Altman’s Concerns About Chip Supply

The rapid emergence of AI-generated content (AIGC) undoubtedly stood out as a highlight of 2023, closely tied to the quality and efficiency of the large language models (LLMs) used. Take OpenAI’s ChatGPT, for instance, which employs the GPT-3.5 model released in 2020. With 175 billion training parameters, it surpasses its predecessor, GPT-2, by over 100 times, itself being over 10 times larger than the initial GPT from 2018.

In pursuit of better content quality, diversified outputs, and enhanced efficiency, the continuous expansion of model training parameters becomes an inevitable trend. While efforts are made to develop lightweight versions of language models for terminal devices, the cloud-based AI computing arena anticipates a continued expansion of language model training parameters, moving towards the “trillion” scale.

Due to the limited growth rate of AI chip performance, coping with the rapidly increasing model training parameters and the vast amount of data generated by the flourishing development of cloud-based AIGC applications inevitably requires relying on more AI chips. This situation continues to exert pressure on the chip supply chain.

Given that the demand for AI computing is escalating faster than the growth rate of chip performance and capacity, it’s understandable why Sam Altman is concerned about chip supply.

• Sam Altman to Seek Collaboration with Foundries for Plant Construction Goal

The construction of advanced process fabs is immensely costly, with estimates suggesting that the construction cost of a single 3nm fab could amount to billions of dollars. Even if Sam Altman manages to raise sufficient funds for plant construction, there remains a lack of advanced semiconductor process and packaging technology, not to mention capacity, yield, and operational efficiency.

Therefore, it is anticipated that Sam Altman will continue to seek collaboration with sfoundries to achieve his factory construction goal.

Looking at foundries worldwide, TSMC is undoubtedly the preferred partner. After all, TSMC not only holds a leading position in advanced processes and packaging technologies but also boasts the most extensive experience in producing customized AI chips.

While Samsung and Intel are also suitable partners from a localization perspective, considering factors like production schedules and yield rates, choosing TSMC appears to be more cost-effective.

Samsung’s flagship mobile processor, the Exynos 2400, produced using the 4LPP+ process technology, currently boasts a yield rate of approximately 60%, as per sources cited by TechNews. While this figure falls short of competitors, notably TSMC’s N4P process technology with yields surpassing 70%, it represents a significant improvement from Samsung’s own 25% yield rate over a year ago.

Samsung’s Exynos 2400 flagship mobile processor is the company’s first to utilize Fan-Out Wafer-Level Packaging (FOWLP). Samsung claims that FOWLP technology enhances heat resistance by 23% and boosts multicore performance by 8%. Consequently, the Exynos 2400 mobile processor delivers commendable performance in the latest 3DMark Wild Life benchmark tests.

In fact, Samsung previously announced plans to commence mass production of the SF3 chip in the second half of 2024, followed by the introduction of its 2-nanometer process technology between 2025 and 2026.

Industry sources cited in the report also indicate that Samsung’s foundry business has begun trial production for its second-generation 3-nanometer process technology, SF3. Furthermore, the company aims to increase its yield rate to over 60% within the next six months.

It is noteworthy that Samsung’s 3nm technology is highly aggressive compared to TSMC’s approach, which will transition to GAA transistors with its 2nm process. Samsung’s first-generation 3nm process already incorporates GAA transistor technology, specifically the MBCFET (Multi-Bridge Channel Field-Effect Transistor), known as SF3E, or 3GAE technology.

As per WeChat account ic211ic cited sources in the report, Samsung’s 3nm GAA technology utilizes wider nanosheets compared to the narrow nanowire GAA technology, offering higher performance and energy efficiency. With the 3nm GAA technology, Samsung can adjust the channel width of nanosheet transistors to optimize power consumption and performance, meeting diverse customer requirements.

Additionally, the flexibility of GAA design is highly advantageous for Design-Technology Co-Optimization (DTCO), contributing to achieving better Power, Performance, and Area (PPA) advantages.

In comparison to Samsung’s 5nm process, the first-generation 3nm process reduces power consumption by 45%, enhances performance by 23%, and decreases chip area by 16%. The upcoming second-generation 3nm process is expected to further reduce power consumption by 50%, boost performance by 30%, and reduce chip area by 35%.
