According to a report from Taiwan’s TechNews, Huawei’s Mate 60 Pro smartphone, powered by its in-house Kirin 9000S processor, quietly appeared on the market recently, testing has shown that its network speed approaches that of 5G. This development has sparked enthusiastic discussions in the market about the manufacturing and development of this chip.

Prominent analyst Andrew Lu also expressed that if the semiconductor manufacturer, SMIC, which handles the production of the Kirin 9000S processor, makes significant breakthroughs in both 7nm process technology and capacity, it should not be underestimated. Additionally, with Huawei’s reintroduction of the Kirin 9000S processor through the Mate 60 Pro, they are expected to continue launching products that are likely to have an impact on the mobile phone and mobile chip market.

Andrew Lu outlined the following points on his personal Facebook fan page:

1. The Kirin 9000S processor is likely manufactured by SMIC using N+2 process technology, with N+1 being a pseudo-7nm process that is closer to 8-9nm. N+2 is a 7nm process (not the rumored 5nm), but it does not use EUV, so multiple exposures are needed. Due to insufficient capacity, shipping 40 million units would likely take several months. Assuming a die size of 169mm² and an 80% yield rate, SMIC would need to prepare 144k N+2 capacity, this indicates a monthly production capacity requirement of 24,000 units. The monthly production capacity appears significantly higher than what was previously anticipated. If these assumptions hold, it indicates that SMIC has made significant breakthroughs in 7nm process technology and capacity.
2. Apple’s iPhone doesn’t emphasize Antutu benchmark scores as much, and Android phones typically fine-tune their systems for benchmarking, making comparisons between iOS and Android phones less fair. However, compared to other Android flagship phones scoring around 1.5-1.6 million, the Mate 60’s 1.1 million still falls short, but it excels in satellite phone functionality.
3. Huawei/Huawei’s HiSilicon’s return is likely to continue with the release of new devices, aiming to reach annual sales of 100 million phones within 5 years, which should not be difficult. This means Huawei/Huawei’s HiSilicon will regain approximately 5-10% of the global market share, while other phone and chip manufacturers will lose 5-10% of their market share with flagship brands likely being more affected.
4. Despite the U.S. putting SMIC on the Entity List, how does SMIC still have so much advanced process capacity? Lu Xingzhi believes that being placed on the Entity List doesn’t entirely prohibit companies from purchasing all advanced U.S. equipment (EUV scanners are absolutely prohibited), but it requires approval from the U.S. Department of Commerce to purchase such equipment. Additionally, the rapid emergence of many semiconductor startups in China (some of which disappear shortly after) makes it challenging for U.S. equipment manufacturers and the U.S. Department of Commerce to determine if the purchased equipment is being resold to SMIC. Therefore, SMIC’s expansion of advanced process capacity is not surprising. According to Lu’s data, SMIC’s capital intensity, capital expenditure as a percentage of revenue, was 110% over the past year, significantly higher than TSMC’s 50% and Samsung LSI’s and GlobalFoundries’ 40% range, indicating that capacity expansion is likely to be considerably higher than peers in the industry.

TSMC’s CoWoS advanced packaging capacity shortage is causing limitations in NVIDIA’s AI chip output. Reports are emerging that NVIDIA is willing to pay a premium for alternative manufacturing capacity outside of TSMC, setting off a surge in massive overflow orders. UMC, the supplier of interposer materials for CoWoS, has reportedly raised prices for super hot runs and initiated plans to double its production capacity to meet client demand. ASE, an advanced packaging provider, is also seeing movement in its pricing.

In response to this, both UMC and ASE declined to comment on pricing and market rumors. In addressing the CoWoS advanced packaging capacity issue, NVIDIA previously confirmed during its financial report conference that it had certified other CoWoS packaging suppliers for capacity support and would collaborate with them to increase production, with industry speculation pointing towards ASE and other professional packaging factories.

TSMC’s CEO, C.C. Wei, openly stated that their advanced packaging capacity is at full utilization, and as the company actively expands its capacity, they will also outsource to professional packaging and testing factories.

It’s understood that the overflow effect from the inadequate CoWoS advanced packaging capacity at TSMC is gradually spreading. As the semiconductor industry as a whole adjusts its inventory, advanced packaging has become a market favorite.

Industry insiders point out that the interposer, acting as a communication medium within small chips, is a critical material in advanced packaging. With a broad uptick in demand for advanced packaging, the market for interposer materials is growing in parallel. Faced with high demand and limited supply, UMC has raised prices for super-hot-run interposer components.

UMC revealed that it has a comprehensive solution in the interposer field, including carriers, customed ASICs, and memory, with cooperation from multiple factories forming a substantial advantage. If other competitors are entering this space now, they might not have the quick responsiveness or abundant peripheral resources that UMC does.

UMC emphasized that compared to competitors, its competitive advantage in the interposer field lies in its open architecture. Currently, UMC’s interposer production primarily takes place in its Singapore plant, with a current capacity of about 3,000 units, with a target of doubling to six or seven thousand to meet customer demand.

Industry analysts attribute TSMC’s tight CoWoS advanced packaging capacity to a sudden surge in NVIDIA’s orders. TSMC’s CoWoS packaging had primarily catered to long-term partners, with production schedules already set, making it unable to provide NVIDIA with additional capacity. Moreover, even with tight capacity, TSMC won’t arbitrarily raise prices, as it would disrupt existing client production schedules. Therefore, NVIDIA’s move to secure additional capacity support through a premium likely involves temporary outsourced partners.

According to a report by Taiwan’s Commercial Times, Goldman Sachs Securities has noted that Intel has been consistently grappling with process upgrade delays since the 10-nanometer fabrication process. Recently, the company has decided to establish a foundry-like relationship between its manufacturing groups and
internal product business units. With the market scale growing increasingly substantial, it is anticipated that Intel will expand its outsourcing to TSMC in 2024 and 2025. In the rising trend of outsourced manufacturing, TSMC stands as the major beneficiary.

Goldman Sachs’ analysis reveals that the total addressable market of Intel’s outsourcing orders for 2024 and 2025 is set at $18.6 billion and $19.4 billion, respectively. During the same period, the total addressable market scope for TSMC’s wafer fabrication services amounts to $5.6 billion and $9.7 billion, approximately accounting for 6.4% and 9.4% of TSMC’s overall revenue in the corresponding years.

Prominent semiconductor industry analyst Andrew Lu also explains that Intel’s wafer chip manufacturing division competes with TSMC, rather than its design division. The design division is striving for survival in the high-speed computing semiconductor sector, and it is currently hopeful for close collaboration with TSMC. Lu even predicts that Intel’s wafer manufacturing and design divisions will inevitably be further separated into two companies several years down the line.

Semiconductor process technology is nearing the boundaries of known physics. In order to continually enhance processor performance, the integration of small chips (chiplets) and heterogeneous Integration has become a prevailing trend. It is also regarded as a primary solution for extending Moore’s Law. Major industry players such as TSMC, Intel, Samsung, and others are vigorously developing these related technologies.

What are SoC, SiP, and Chiplet?

To understand Chiplet technology, we must first clarify two commonly used terms: SoC and SiP. SoC (System on Chip) involves redesigning multiple different chips to utilize the same manufacturing process and integrating them onto a single chip. On the other hand, SiP (System in Package) connects multiple chips with different manufacturing processes using heterogeneous integration techniques and integrates them within a single packaging form.

Chiplet technology employs advanced packaging techniques to create a SiP composed of multiple small chips. It integrates small chips with different functions onto a single substrate through advanced packaging techniques. While Chiplets and SiPs may seem similar, Chiplets are essentially chips themselves, whereas SiP refers to the packaging form. They have differences in functionality and purpose.

Chiplets: Today’s Semiconductor Development Trend

The design concept of Chiplet technology offers several advantages over SoC, notably in significantly improving chip manufacturing yield. As chip sizes increase to enhance performance, chip yield decreases due to the larger surface area. Chiplet technology can integrate various smaller chips with relatively high manufacturing yields, thus enhancing chip performance and yield.

Furthermore, Chiplet technology contributes to reduced design complexity and costs. Through heterogeneous integration, Chiplets can combine various types of small chips, reducing integration challenges in the initial design phase and facilitating design and testing. Additionally, since different Chiplets can be independently optimized, the final integrated product often achieves better overall performance.

Chiplets have the potential to lower wafer manufacturing costs. Apart from CPUs and GPUs, other units within chips can perform well without relying on advanced processes. Chiplets enable different functional small chips to use the most suitable manufacturing process, contributing to cost reduction.

With the evolution of semiconductor processes, chip design has become more challenging and complex, leading to rising design costs. In this context, Chiplet technology, which simplifies design and manufacturing processes, effectively enhances chip performance, and extends Moore’s Law, holds significant promise.

Applications and Development of Chiplets

In recent years, global semiconductor giants like AMD, TSMC, Intel, NVIDIA, and others have recognized the market potential in this field, intensively investing in Chiplet technology. For example, AMD’s recent products have benefited from the ‘SiP + Chiplet’ manufacturing approach. Moreover, Apple’s M1 Ultra chip achieved high performance through a customed UltraFusion packaging architecture. In academia, institutions like the University of California, Georgia Tech, and European research organizations have begun researching interconnect interfaces, packaging, and applications related to Chiplet technology.

In conclusion, due to Chiplet technology’s ability to lower design costs, reduce development time, enhance design flexibility and yield, while expanding chip functionality, it is an indispensable solution in the ongoing development of high-performance chips.

According to a report by Taiwan’s TechNews, the Huawei Kirin 9000S mobile processor, dubbed by Chinese media as “4G technology with 5G speed,” was incorporated into the Huawei Mate 60 Pro smartphone on the 29th. The phone was made available for purchase directly without a launch event or prior promotion, priced at 6,999 Chinese Yuan, sparking significant industry discussion.

The discussion around the Huawei Kirin 9000S mobile processor stems from the fact that, for the first time post the US-China trade war, a chip foundry has manufactured chips for Huawei, featuring an advanced 5-nanometer process. Does this signify a breakthrough for Chinese chip production amidst US restrictions and a leap forward in China’s semiconductor industry? At present, the answer seems to be negative.

According to insiders’ revelations, the Mate 60 Pro’s Kirin 9000S chip was manufactured by SMIC. However, key production aspects are still under US control, making breaking through these limitations quite challenging.

Screenshots shared by users indicate that Kirin is on a 5nm process. Nonetheless, technical experts widely believe that the 9000S isn’t on a 5nm process; rather, it’s on SMIC’s N+2 process.

SMIC is the only Chinese enterprise capable of mass-producing 14-nanometer FinFET technology. Both N+1 and N+2 processes are improvements based on the 14nm FinFET technology and are achieved through DUV lithography, bypassing US restrictions. (The most advanced processes currently require EUV lithography machines.)

SMIC has not openly stated that N+1 and N+2 are on the 7nm process. However, the chip industry generally considers N+1 to be equivalent to 7nm LPE (Low Power) technology, and N+2 to be equivalent to 7nm LPP (High Performance) technology. The shipment of the Mate 60 Pro seems to have openly revealed information about SMIC’s N+2 process reaching maturity and entering mass production.
