Driven by booming demand for AI chips, TSMC’s advanced CoWoS (Chip on Wafer on Substrate) packaging faces a significant supply shortage. In response, TSMC is expanding its production capacity and is considering price increases to maintain supply chain stability.

According to a recent report from Morgan Stanley cited by Commercial Times, TSMC has received approval from NVIDIA to raise prices next year, with CoWoS packaging expected to increase by 10% to 20%, depending on capacity expansion.

At TSMC’s Q3 earnings call, Chairman C.C. Wei highlighted that customer demand for CoWoS far outstrips supply. Despite TSMC’s plan to more than double CoWoS capacity in 2024 compared to 2023, supply constraints persist.

To meet demand, TSMC is collaborating closely with packaging and testing firms to expand CoWoS capacity. Industry sources quoted by CNA reveal that ASE Group and SPIL are working with TSMC on the back-end CoWoS-S oS (on-Substrate) process. By 2025, ASE may handle 40-50% of TSMC’s outsourced CoWoS-S oS packaging.

ASE announced investments in advanced packaging, covering CoWoS front-end (Chip on Wafer) and oS processes, along with advanced testing.

SPIL, a subsidiary of ASE, recently invested NT$419 million in land at Central Taiwan Science Park’s Erlin Park, boosting CoWoS capacity. Additionally, SPIL has allocated NT$3.702 billion to acquire property from Ming Hwei Energy in Douliu, Yunlin, for further expansion.

ASE also announced in early October that its new Kaohsiung K28 facility, slated for completion in 2026, will expand CoWoS capacity.

In early October, TSMC announced a partnership with Amkor in Arizona to expand InFO and CoWoS packaging capabilities. Industry sources cited by CNA suggest that Apple, a user of TSMC’s U.S.-based 4nm process for application processors, may leverage Amkor’s CoWoS capacity. Other U.S.-based AI clients utilizing TSMC’s advanced nodes for ASICs and GPUs are also expected to consider Amkor’s CoWoS packaging in the future.

Google has accelerate its pace on the Pixel series, as the tech giant launched Google Pixel 9 on August 13th, which is two months ahead of its schedule.

Though the Tensor G4 processor in the model is manufactured with Samsung’s 4nm, according to a report citing sources by Commercial Times, Google is said to be switching to TSMC’s 3nm process with its next-generation Tensor G5, coupling with the foundry giant’s InFO-POP packaging.

Google’s Pixel 8 is said to be the first AI-centric smartphone, featuring a range of AI functionalities. Yet, Commercial Times’ report has indicated that, after years of close collaboration, Google will part ways with Samsung and have TSMC produce the Tensor G5 chip.

The chip is also said to adopt TSMC’s advanced InFO-POP packaging. Google’s move, according to the report, demonstrates its ambition to expand its leadership in software to hardware, as it eyes for the opportunities of edge AI.

Industry sources cited by the report further point out that in the fourth quarter, both Qualcomm and MediaTek will launch flagship-level chips, while Apple’s A18 will also be produced using TSMC’s N3 process.

All these developments have hinted at tech giants’ ambition on the massive potential of the edge AI market. Now, Google would be the latest competitor to join the race.

Meanwhile, though Pixel’s market share is relatively low, the Android ecosystem, with its 70% market share in smartphones and billions of users, offers significant potential. Google is said to be following a path similar to Apple’s, achieving complete integration of hardware and software to maximize this potential.

Google’s self-developed chip extends beyond mobile devices, with its TPU (Tensor Processing Unit) now in their seventh generation. Additionally, Google’s Arm-based CPUs are being developed in partnership with TSMC.

TSMC’s fan-out (InFO) packaging process will no longer be exclusively used by Apple. According to a report from Commercial Times, it’s revealed that Google’s self-developed Tensor chips for their phones will switch to TSMC’s 3nm process next year and will also start using InFO packaging.

TSMC developed InFO packaging based on FOWLP (fan-out wafer-level packaging), which gained prominence after being adopted by the A10 processor in the iPhone 7 in 2016.

TSMC indicated that the current InFO_PoP technology has advanced to its ninth generation. Last year, it successfully certified 3nm chips, achieving higher efficiency and lower power consumption for mobile devices. The InFO_PoP technology, which features a backside redistribution layer (RDL), has entered mass production this year.

According to industry sources cited by the Commercial Times, Google will shift to TSMC for the Tensor G5 chips, which will be used in the Pixel 10 series next year. These chips will not only utilize the 3nm process but will also adopt integrated fan-out packaging.

This year’s Tensor G4 chips, set to be announced soon, use Samsung’s FOPLP (fan-out panel-level packaging). Although wafer-level packaging (WLP) is generally considered to have advantages over panel-level packaging (PLP), FOWLP still prevails at this stage due to yield and cost considerations.

TSMC has also begun developing FOPLP technology. Previously, per sources cited by a report from MoneyDJ, TSMC has officially formed a team, currently in the “Pathfinding” phase, and is planning to establish a mini line with a clear goal of advancing beyond traditional methods.

Although it is not expected to mature within the next three years, major customers like NVIDIA have partnered with foundry companies to develop new materials. One of TSMC’s major clients has already provided specifications for using glass materials.

Traditionally, chip advancements have been achieved through more advanced process nodes. However, new materials could enable the integration of more transistors on a single chip, achieving the same goal of scaling.

For instance, Intel plans to use glass substrates by 2030, potentially allowing a single chip to house one trillion transistors – 50 times the number in Apple’s A17 Pro processor. This suggests that glass substrates could become a significant milestone in chip development.

Another sources cited by Commercial Times have also indicated that glass substrates are part of the medium- to long-term technological roadmap. They can address challenges in large-size, high-density interconnect substrate development.

Currently, this technology is in the early stages of research and development. Its impact on ABF (Ajinomoto Build-up Film) substrates is expected to become significant in the second half of 2027 or later.

According to a report by Taiwan’s Commercial Times, TSMC is facing a tight supply of advanced packaging capacity, with its Taichung factory ramping up equipment support at a rapid pace. Industry insiders have disclosed that TSMC’s annual production capacity for the backend CoWoS (Chip-on-Wafer-on-Substrate) advanced packaging is only 150,000 to 300,000 units, falling short of customer demand by over 20%.

To address this shortfall, TSMC officially inaugurated its advanced packaging and testing Plant 6 in Zhunan in June. TSMC’s management has also committed to steadily increasing CoWoS production capacity each quarter, and third-party testing facilities are being actively engaged to bridge the gap.

It is worth noting that TSMC’s Longtan factory has traditionally been a key hub for CoWoS and InFO (Integrated Fan-Out) packaging, with a primary focus on InFO production at approximately 100,000 units per month and a smaller portion allocated to CoWoS. Although some of the InFO capacity has been relocated to the Southern Taiwan Science Park, Longtan’s physical space constraints continue to make Zhunan the primary location for CoWoS expansion. TSMC’s Taichung AP5 factory, on the other hand, is prioritizing WoS (Wafer-on-Substrate) expansion, with CoW (Chip-on-Wafer) expansion slated to commence next year. Many equipment suppliers have reportedly received urgent orders related to these expansion efforts.

Analysts estimate that this year’s overall CoWoS production will reach 110,000 units, doubling to 250,000 units next year. However, analysts caution that while TSMC currently dominates the CoWoS production landscape, other players are gradually entering the field. Therefore, it is crucial to monitor whether an oversupply situation may emerge in the mid-term next year.
