• 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%.

Industry sources cited by Reuters have revealed that Huawei, the Chinese telecommunications giant, is slowing down the production of its high-end Mate 60 series smartphone due to surging demand in the AI chip market and production constraints. Instead, the company has decided to prioritize the production of AI chips from its Ascend series, diverging from the Kirin chips used in the Mate 60 series.

According to a report by Reuters on January 5th, Huawei is utilizing a plant to simultaneously produce chips from the Ascend series and the Kirin series. The current plan is to prioritize the production of Ascend chips over Kirin chips, although the exact starting date for this arrangement has not been disclosed.

On the other hand, the production volume of Huawei’s Mate 60 series, launched in August last year, has been hampered by low chip yields. Reportedly, Huawei is actively working to improve chip yields, and it is hoped that the mentioned production adjustment will be a short-term measure.

It’s worth noting that many Huawei products have recently been affected by production bottlenecks. The computation components for Huawei’s assisted driving system have encountered production issues due to shortages of components.

This has led to delays in the delivery of flagship models from Changan Automobile, Chery Automobile, and Seres. Changan Automobile and Chery Automobile have already filed complaints and are currently in negotiations with Huawei.

Reports have indicated that since 2019, the U.S. government has imposed sanctions on Huawei, citing national security concerns, thereby cutting off Huawei’s access to advanced chip manufacturing equipment and technology and weakening its smartphone division. In response, Huawei denies posing any security risks and is actively working to rebuild its business.

In addition, Bloomberg previously reported that the Chinese government has also been directly investing to assist Huawei in building its chip supply chain since 2019, creating an exclusive supply chain for Huawei in response to the tighten restrictions.

In October 2023, the U.S. further strengthened restrictions on the export of advanced chips and chip manufacturing equipment to China, building upon previous limitations. This move forced Chinese customers to turn to domestic alternatives. Huawei’s Ascend 910B chip is considered the most competitive non-NVIDIA chip available in the Chinese market.

Huawei has maintained a low profile regarding its chip manufacturing capabilities and objectives. There is limited public information about its progress or how it successfully produces advanced chips.

In August 2023, during U.S. Commerce Secretary Gina Raimondo’s visit to China, Huawei launched the Mate 60 series, garnering significant market attention.

In a bid to enhance its foundry capabilities, Samsung is earnestly integrating hybrid bonding technology. According to industry sources, Applied Materials and Besi Semiconductor are establishing equipment for hybrid bonding at the Cheonan Campus, slated for use in next-generation packaging solutions like X-Cube and SAINT.

According to a report from South Korean media outlet The Elec, industry sources have indicated that Applied Materials and Besi Semiconductor are installing hybrid bonding equipment at Samsung’s Cheonan Campus, a key site for advanced packaging production. Officials from the South Korean industry also mentioned that a production line is currently under construction, with the equipment intended for non-memory packaging.

Compared to existing bonding methods, hybrid bonding enhances I/O and wiring lengths. Samsung’s latest investment is expected to strengthen its advanced packaging capabilities, introducing the X-Cube utilizing hybrid bonding technology.

Industry sources cited by the report have suggested that hybrid bonding could also be applied to Samsung’s SAINT (Samsung Advanced Interconnect Technology) platform, which the company began introducing this year. The platform includes three types of 3D stacking technologies: SAINT S, SAINT L, and SAINT D.

SAINT S involves vertically stacking SRAM on logic chips such as CPUs. SAINT L involves stacking logic chips on top of other logic chips or application processors (APs). SAINT D entails vertical stacking of DRAM with logic chips like CPUs and GPUs.

TSMC, the leading semiconductor foundry, also offers hybrid bonding in its System on Integrated Chip (SoIC) for 3D packaging services, which is similarly provided by Applied Materials and Besi Semiconductor. Intel has also applied hybrid bonding technology in its 3D packaging technology, Foveros Direct, which was commercialized last year.

Reportedly, industry sources anticipate that Samsung’s investment in hybrid bonding facilities is poised to attract major clients such as NVIDIA and AMD. This is because the demand for hybrid bonding among fabless customers is steadily increasing.

TrendForce has released the latest panel quotations for early February. Due to the effective production control strategies implemented by panel manufacturers, there is an expectation of gradually stimulating panel demand. It is anticipated that TV panel prices will return to an upward trend in February. Details are as follows:

• TV

From the perspective of panel suppliers, with the reduction in working days and the Lunar New Year holiday in February, it is expected that the average utilization rate will fall below 60%. Coupled with the relatively low TV panel inventory in the supply chain, the production control strategies of panel manufacturers have been effective. There is an anticipation of gradually stimulating the recovery of TV panel demand.

Meanwhile, the upstream supply issues with polarizing film materials have exacerbated, and it is expected that TV panel prices will return to an upward trend in February. Currently, it is expected that 32-inch, 43-inch, and 50-inch panels will increase by 1 USD, 55-inch by 2 USD, and 65-inch and 75-inch by 3 USD in February.

• Monitor

Although monitor panel demand is in the off-season, due to panel production cuts, unstable conditions in the shipping industry, and supply issues with polarizing film materials, some customers are observed to be willing to increase orders to mitigate potential risks. Additionally, with the established upward trend in TV panel prices in February, panel manufacturers are more confident, and it is expected that open-cell panels will increase by 0.1 to 0.2 USD. Panel module prices, however, are expected to remain overall stable.

• Notebook

Notebook panel demand is still in the off-season in the first quarter, and with sluggish demand, brand customers continue to request panel manufacturers to maintain the trend of price reductions. Different panel manufacturers respond differently to this pressure. Newer entrants are actively seeking to expand market share, leading to a more aggressive pricing strategy, putting pressure on existing panel manufacturers. In this competitive situation, notebook panel prices are not easily expected to see a comprehensive stabilization. In February, only TN models are expected to maintain a stable trend, while FHD IPS models are expected to decrease by 0.1 USD, and 16:10 models are expected to decrease by 0.2 to 0.3 USD.
