While Taiwanese foundries are reportedly facing price pressure in mature nodes and are said to be offering discounts, TSMC is also rumored to mull about offering discounts to its customers on mature nodes, particular for 7nm and 14nm, a report by Commercial Times indicates.

Sources cited by the report suggest that the foundry giant’s latest move would be a countermeasure to the competition from Samsung and other Chinese foundries.

A previous report by the Economic Daily News notes that local foundries in Taiwan, such as United Microelectronics Corp. (UMC), Vanguard International Semiconductor Corp. (VIS), and Powerchip Semiconductor Manufacturing Corp. (PSMC), are already offering discounts on mature process orders in the fourth quarter, marking a shift from the relatively stable pricing seen in the third quarter.

Now, TSMC seems to follow suit. The report by Commercial Times indicates that this move will boost capacity utilization for TSMC’s mature processes, while offsetting the risk of declining average selling prices (ASP) due to heated competition.

Looking ahead to next year, the pricing pressure on mature processes will likely persist, as TSMC may lead the way in offering discounts for some of its mature nodes, the report notes. Volume would reportedly play a key role in securing discounts, as TSMC may allow more flexibility in pricing with massive orders.

It is worth noting that Chinese foundries, which had previously been aggressive in cutting prices, have held firm this time. As these companies are struggling to make profit, they have signaled potential price increases, according to the report.

Therefore, it is indicated that certain Taiwanese IC design companies have increased their orders with local foundries. By working on price negotiations with different suppliers, they can further optimize their cost structure.

Sources in the supply chain cited by the report also indicate that in the past, Taiwanese foundries were often forced to follow their Chinese rivals in cutting prices due to aggressive competition. However, as Chinese manufacturers have been gradually balancing their supply and demand, Taiwanese companies hope to seize this opportunity by offering greater pricing flexibility this time, allowing their customers to negotiate based on the volume to expand market share and boost capacity utilization.

The other three major foundries in Taiwan, as mentioned above, had seen their utilization rates rising above 70% in the third quarter, the report suggests. However, if the foundries aim to further increase their capacity utilization, they will inevitably need to move away from the relatively passive order-taking strategies they used to adopt.

In terms of the market demand in 2025, sources from IC design firms cited by the report note that there may still be room for price adjustments. For now, the demand for advanced nodes, which are driven by AI and smartphones, seems to remain solid. However, the demand from automotive and industrial control sectors has yet to show a clear recovery, which may be inferred from the moderate price discounts offered by Taiwanese manufacturers, according to the report.

Contract chip manufacturer United Microelectronics Corp has partnered with Intel to develop a 12-nanometer technology platform and will commence production at three Intel facilities in Arizona, USA. According to a report by Nikkei, mass production for chips destined for communication and other applications is slated to begin in 2027

During an interview at the Intel IFS Direct Connect event in February, Jason Wang, Co-President of UMC, stated that both UMC and Intel are pioneering innovative collaboration models. They aim to provide customers with foundry services with competitive pricing through vertical specialization. The two companies will leverage complementary advantages to accelerate the development timeline and expand their global presence.

The foundry market is generally divided into advanced chips and mature chips. Advanced chips, which constitute the brains of smartphones and other devices, are predominantly led by TSMC and Samsung Electronics.

In the realm of mature chips, around 10 companies from Taiwan, China, South Korea, and the United States are competing for the demands of telecommunications equipment, Vehicular communication systems, and other technology manufacturers.

Intel is changing its vertically integrated business model to compete with TSMC and Samsung in contract manufacturing demands.

In March of this year, the US government announced that Intel would receive up to USD 8.5 billion in subsidies for the development of advanced chips. By collaborating with UMC on mature chips, Intel may focus more resources on cutting-edge technologies like 1.4nm.

For UMC, partnering with Intel enables it to mass-produce chips that are more advanced than its mainstream 22nm to 28nm products. Obtaining production facilities in the United States will also help the company win North American clients, as revenue from this region currently accounts for less than 30% of its total.

TSMC is also constructing a semiconductor plant in Arizona, utilizing US assistance to produce advanced 4nm chips. In contrast, the collaboration between UMC and Intel will focus on relatively mature chips.

UMC has long been one of the pillars of the semiconductor industry in Taiwan. Established in 1980, seven years before TSMC, the company has been vying for the position of industry leader until the 2000s.

During the 2010s, UMC lagged behind TSMC in advanced chip development, as the latter made significant investments in the semiconductor market following the global financial crisis. Since then, UMC has reportedly put more emphasis on mature chips.

The company is currently at a turning point. Benefiting from the global chip shortage, its performance continued to grow from 2020 to 2022. However, as of December 2023, annual revenue declined by 20% to 222.5 billion New Taiwan dollars ($6.9 billion), marking the first decrease in four years. This is approximately one-tenth of TSMC’s revenue.

UMC’s downturn in 2023 also signifies an intensification in mature process technologies, especially as Chinese semiconductor enterprises’ mature process technologies and equipment remain unaffected by US export restrictions. In an effort to overcome US restrictions, China is heavily investing in mature process.

Per data from TrendForce, China’s share of mature chip production at 28nm and above is expected to increase from the current 31% to 39% by 2027, as production volumes grow.

Joanne Chiao stated that semiconductors for applications such as general sensors and display controllers are expected to face fierce price competition.

On the other hand, UMC continues to face competition from Taiwanese foundries. TSMC plans to produce mature chips at a new plant in Japan by the end of 2024 and at a plant in Germany by the end of 2027. With subsidies from the Japanese and German governments, TSMC will form joint ventures with buyer customers to ensure stable production capacity.

Powerchip Semiconductor Manufacturing Corporation (PSMC) announced at the end of February its plans to assist Tata Group in building a chip plant in India. PSMC stated that it would provide intellectual property for the project without investment, aiming to generate licensing revenue.

Despite the U.S. sanction on the semiconductor industry in China, China is still positively looking for further development.

Following our discussion on the shifts of Chinese wafer fabs in the previous article (China’s Wafer Fabs Hits 44 with Future Expansion 32, Mainly Targeting on The Mature Process), this article focuses on the application of 8-inch and 12-inch wafers, as well as provides detailed account of Chinese foundries’ strategic positioning in the landscape.

From a cost perspective, producing a 12-inch wafer incurs approximately 50% more cost than an 8-inch wafer. However, the chip output from a 12-inch wafer is nearly triple that of an 8-inch wafer, leading to a cost reduction of roughly 30% per chip. As manufacturing processes improve and yields increase, the cost of 12-inch wafers is expected to further decline in the future.

In terms of applications, a clear distinction emerges between 12-inch and 8-inch wafers. The versatility of 12-inch wafers is evident, covering a broad range of practical applications. As depicted in the table below, 8-inch wafers are primarily utilized for mature and specialized processes, focusing on the 0.13-90nm range.

8-inch wafers’ downstream applications are concentrated in industrial, mobile, and automotive sectors, encompassing power devices, power management chips, non-volatile memory, MEMS, display driver ICs, and fingerprint recognition chips, among others. The surging demand for power devices in automotive electronics and industrial applications has been a key driver for recent production expansions.

Currently, the market demand for 8-inch wafers remains robust. However, there is a trend of decreasing 8-inch production lines in the market. This shift is primarily due to the industry’s mainstream adoption of 12-inch wafers. Given the significant capital required to establish 12-inch wafer fabs (often exceeding billions of US dollars), many foundries are reevaluating their 8-inch wafer production lines. These lines face challenges such as outdated equipment (mostly sourced from the second-hand market), upgrades difficulties, and lower returns compared to 12-inch wafers. Consequently, an increasing number of major companies are transitioning their focus from 8-inch to 12-inch wafers.

While the quantity of 8-inch wafer fabs is far less than that of 12-inch wafer fabs, their presence is significant. According to data from SEMI, China has maintained rapid development in 8-inch wafers. It is projected that by 2026, China’s market share in 8-inch wafers will increase to 22%, with a monthly production capacity reaching 1.7 million wafers, ranking first globally. By the end of 2025, companies including Huahong, Sien, Silan, Yangdong Microelectronic, GTA Semiconductor, SMEIIC, Zkjx, Hwdz, and Eaerkey are expected to establish a total of nine new 8-inch wafer fabs.

China’s Semiconductor Focus: 33% Mature Process Capacity by 2027

Based on product requirements, we can categorize semiconductor processes into specialty processes and logic processes. Logic processes further divide into mature processes (28nm and above) and advanced processes (nodes below 28nm, primarily 16/14nm and below).

Considering the current scenario, challenges in advanced process technology and high expenditures have confined major players in advanced processes to Intel, TSMC, and Samsung. This year, Samsung and TSMC announced the mass production of 3nm processes, marking the most advanced nodes currently available. Examining China’s situation, the semiconductor industry, having started relatively late, is currently focusing on mature and specialty processes due to factors like equipment and material limitations and changes in the international landscape.

It’s worth noting that, apart from Chinese wafer fabs intensively researching mature processes, many major companies have started to reverse their focus on mature processes in the past two years. Companies such as TSMC, Samsung, Intel, UMC, and GlobalFoundries are actively expanding their mature process capacities.

Among them, UMC’s bet on mature capacities is unprecedented. It became the world’s first wafer foundry to announce leaving research and development of advanced processes. Since 2018, UMC has strategically focused on improving the company’s return on investment, particularly targeting processes of 28nm and above.

According to TrendForce, the compound annual growth rate of global semiconductor foundry capacities from 2021 to 2024 is expected to reach 11%. 28nm capacity is expected to be 1.3 times that of 2022 by 2024, making it the most actively expanded node in mature processes. It is anticipated that more applications of specialty processes will transition to 28nm. Moreover, from 2021 to 2024, the global capacity of mature processes (28nm and above) is expected to maintain a stable share of over 75%. This indicates the potential and significance of positioning in the mature process and specialty process markets.

TrendForce predicts that, with the expansion of mature process capacities below 28nm, mature process capacities are expected to account for 70% of the top ten foundries’ capacities by 2027. China is expected to hold 33% of mature process capacities in 2027, with the possibility of continuous upward adjustments.

According to the news from ChinaTimes, the semiconductor market is experiencing a slowdown, with Taiwan’s three major mature process wafer foundries UMC, VIS, and PSMC all reporting reduced revenues in August. VIS and UMC both posted lower revenues compared to the previous month, while PSMC managed a slight 1.2% monthly increase in August. However, this increase still falls within this year’s relatively low range. Industry experts anticipate that the semiconductor industry will maintain a subdued market outlook in the latter half of this year, with a potential recovery likely delayed until the first half of the next year.

The semiconductor industry began its correction in the second half of last year. Initially, there was optimism for inventory adjustments to conclude within four quarters by the end of this year’s second quarter, anticipating a demand rebound in the latter half of the year. However, since the second quarter, semiconductor manufacturers have grown pessimistic due to slower downstream inventory depletion and weak end-user demand. This is reflected in third-quarter revenues for mature process wafer foundries, which are expected to remain flat or slightly decline based on August revenues. A robust recovery in the fourth quarter is unlikely, suggesting that industry-wide recovery is likely postponed until the first half of next year.

UMC saw consecutive monthly revenue growth from February to July. However, following five consecutive increases, the company experienced a slight decrease in revenue in August. TSMC previously stated in a conference that the current market recovery falls short of expectations, with an unclear outlook for wafer demand. It anticipates a 3~4% quarter-on-quarter decrease in wafer shipments in the third quarter, which aligns with the market’s expectations for a slight decline in August revenue.

UMC forecasts a 3~4% quarter-on-quarter decrease in wafer shipments in the third quarter, a 2% quarter-on-quarter increase in the average wafer price in USD, a low single-digit percentage decrease in the average gross margin, and an approximate 65% capacity utilization rate. Overall, industry insiders expect TSMC to face slight downward pressure on third-quarter revenue.

VIS reported July revenue reaching NT$3.596 billion, marking a new high for the first seven months of the year. However, its August revenue showed a decline, with a 2.23% month-on-month decrease to NT$3.516 billion. This is significantly different from the typical revenue growth momentum observed during the third-quarter peak season in previous years. Cumulative revenue for the first eight months of this year also decreased by 34.54% compared to the same period last year.

VIS anticipates a 4~6% quarter-on-quarter increase in wafer shipments in the third quarter, with a capacity utilization rate similar to that of the second quarter, around 60%. The average selling price (ASP) is expected to remain stable. However, due to increased production costs and depreciation expenses, the gross margin is estimated to decline to 25~27% in the third quarter, putting more pressure on profitability compared to revenue.

As for PSMC, although its August revenue saw a slight 1.2% month-on-month increase, the company has maintained around NTD 3.4 billion in monthly revenue from June to August, which is considered a low level compared to the second quarter when monthly revenue was approximately NTD 3.8 billion. The third quarter is expected to continue to exert downward pressure on revenue compared to the previous quarter. The company has also previously stated that it does not rule out the possibility of a quarterly loss in its core business during the third quarter.
