According to a report by China’s financial media outlet Yicai, in 2023, China’s import quantity and value of integrated circuits experienced a significant decline, influenced by factors such as the overall downturn in the global chip market and the U.S. ban on the sale of chips to China.

The latest data from the Chinese Customs Administration indicates that in 2023, China imported a total of 479.5 billion integrated circuits, a 10.8% decrease compared to 2022, with an import value of $349.4 billion, marking a 15.4% year-on-year decline.

Industry experts suggest that the soft importation of integrated circuits and semiconductor equipment in China reflects the global economic headwinds in 2023, especially the impact of sluggish sales of Chinese smartphones and laptops. Simultaneously, Chinese companies are striving to increase domestic chip production to reduce dependence on imported chips.

Despite the time required for China to achieve mass production in the field of artificial intelligence chips, the push by the Chinese government to establish a more resilient chip supply chain has motivated local manufacturers to actively increase production capacity in mature nodes. These chips are used in devices such as automobiles and home appliances, unaffected by the current U.S. restrictions.

Public information reveals that SMIC, Hua Hong Group, and Nexchip are among the most active in expanding production, focusing on specialty processes such as driver ICs, CIS/ISP, and power semiconductor ICs.

With China’s significant investment in mature nodes, it is positioned at a time when the global chip industry is poised for recovery. According to a recent TrendForce’s data, China currently has 44 operational semiconductor wafer fabs, with an additional 22 under construction. By the end of 2024, 32 Chinese wafer fabs will expand their capacity for 28-nanometer and older mature chips.

TrendForce predicts that by 2027, China’s share of mature process capacity in the global market will increase from 31% in 2023 to 39%, with further growth potential if equipment procurement progresses smoothly.

According to a report from IJIWEI, research by Barclays analysts indicates that China’s chip manufacturing capacity is expected to more than double within the next 5 to 7 years, surpassing market expectations significantly. The analysis of 48 chip manufacturers with production facilities in China suggests that 60% of the expected additional capacity may come online within the next 3 years.

TrendForce statistics reveal that, excluding 7 dormant wafer fabs, China currently has 44 wafer fabs, with 25 of them being 12-inch facilities, 4 of them 6-inch, and 15 8-inch wafer fabs/lines. Additionally, there are 22 wafer fabs under construction, with 15 of them being 12-inch facilities and 8 being 8-inch wafer fabs.

Companies like SMIC, Nexchip, CXMT and Silan plan to construct 10 more wafer fabs, including 9 12-inch and 1 8-inch wafer fab, by the end of 2024, bringing the total to 32 large-scale wafer fabs, all focusing on mature processes.

Chinese firms have accelerated the procurement of crucial chip manufacturing equipment to support capacity expansion. According to the previous report from South China Morning Post, the import value of lithography equipment from the Netherlands, a primary exporter, surged by 1050%, reflecting substantial orders for semiconductor equipment from China in 2023.

Barclays analysts suggest that most of the new capacity will be used for producing chips using older technologies. These mature semiconductors (28nm and above) lag behind the most advanced chips by at least a decade but are widely used in household appliances and automotive systems.

While these chips could theoretically lead to a market oversupply, Barclays believes it will take several years, possibly as early as 2026, depending on quality and any new trade restrictions.

Earlier, TrendForce released statistics projecting a global ratio of mature (>28nm) to advanced (<16nm) processes around 7:3 from 2023 to 2027. With China’s mature process capacity expected to grow from 29% to 33% by 2027, driven by policies promoting local production, giants like SMIC and HuaHong Group are anticipated to lead the charge, potentially causing a flood of mature processes into the global market and triggering a price war.

TrendForce notes that as China’s mature process capacities emerge, localization trends for Driver IC, CIS/ISP, and Power Discretes will become more pronounced, leading to risks of client attrition and pricing pressures for second and third-tier foundries with similar processes.

China is actively investing in chips with a mature process of 20nm and above. According to Chosun Ilbo, some insiders signal a potential shift of over 50% of global mature-node chips production to China within the next 2 to 3 years. As semiconductors focusing on mature process account for 75% of overall chip demand, China’s growing influence in this sector raises significant security concerns.

During the APEC SME Technology Conference and Fair in Qingdao on the 9th of this month, Wei Li, former Vice President of SMIC, emphasized the necessity for China to prioritize the localization of semiconductors with a 20nm process and above. This category includes semiconductors focusing on mature process, where Li acknowledged China’s technology lags behind international counterparts by more than 5 years.

Despite China’s efforts for independent development, the semiconductor industry faces comprehensive restrictions from the United States, heavily relying on imports for materials, equipment, and design software, with only about 10% being domestically produced. China, holding over 1/3 of the global chip market, struggles with a self-sufficiency rate below 15%, hindering its industrial progress, especially with foreign countries imposing export controls on advanced process and equipment.

According to South Korean media reports, concerns have arisen within the industry about the potential impact on the global semiconductor supply chain as China expands its mature processes. Despite the recent surge in demand for advanced chips like AI chips and servers, semiconductors focusing on mature process still constitute 75% of overall demand. These chips are crucial not only in autonomous vehicles, automobiles, and home appliances but also in military applications. If China monopolizes this market, it could lead to a severe security crisis.

China is rapidly increasing its market share in the mature-node chips sector, with the government offering up to a 10-year corporate tax exemption for new domestic semiconductor plants. Last year, SMIC invested USD 8.9 billion in Shanghai to build a 28nm plant.

Data from TrendForce indicates that China plans to construct 32 semiconductor plants by 2024, surpassing Taiwan’s 19 and the United States’ 12.

China’s Wafer Fabs Hits 44 with Future Expansion 32, Mainly Targeting on The Mature Process

China’s Expansion into the mature process market poses big challenges for Korean enterprises. Chinese companies are gaining ground in various sectors, including the image sensor market, encompassing DDI semiconductors used in OLED panels. Beyond manufacturing capabilities, China has achieved noteworthy levels of design expertise in semiconductor technologies.

On the other hand, in previous press release, TrendForce predicted China’s mature process capacity to grow from 29% this year to 33% by 2027. Leading the charge are giants like SMIC, Hua Hong Group, and Nexchip, while Taiwan’s share is estimated to consolidate from 49% down to 42%.

TSMC, UMC, and Samsung are the frontrunners in this technology currently. Yet, Chinese players like SMIC and Nexchip are hot on their heels, swiftly closing the gap. SMIC’s 28HV and Nexchip’s 40HV are gearing up for mass production in 4Q23 and 1H24, respectively—narrowing their technological gap with other foundries.

TrendForce reports that from 2023 to 2027, the global ratio of mature (>28nm) to advanced (<16nm) processes is projected to hover around 7:3. Propelled by policies and incentives promoting local production and domestic IC development, China’s mature process capacity is anticipated to grow from 29% this year to 33% by 2027. Leading the charge are giants like SMIC, HuaHong Group, and Nexchip, while Taiwan’s share is estimated to consolidate from 49% down to 42%.

Expansion predominantly targets specialty processes such as Driver ICs, CIS/ISPs, and Power Discretes, with second and third-tier Taiwanese manufacturers at the forefront

Within the Driver IC sector, the spotlight is on high voltage (HV) specialty processes. As companies aggressively pursue the 40/28nm HV process, UMC currently dominates, trailed by GlobalFoundries. Yet, SMIC’s 28HV and Nexchip’s 40HV are gearing up for mass production in 4Q23 and 1H24, respectively—narrowing their technological gap with other foundries. Notably, competitors with similar process capabilities and capacities, such as PSMC, and those without twelve-inch factories like Vanguard and DBHitek, are poised to face challenges head-on in the short term. This trend may also have long-term implications for UMC and GlobalFoundries.

In the realm of CIS/ISP, 3D CIS structure comprises a logic layer ISP and CIS pixel layer. The primary demarcation for mainstream processes is around 45/40nm range for the logic layer ISP, which continues to progress toward more advanced nodes. Meanwhile, the CIS pixel layer, along with FSI/BSI CIS, predominantly uses 65/55nm and above processes. Currently, TSMC, UMC, and Samsung are the frontrunners in this technology. Yet, Chinese players like SMIC and Nexchip are hot on their heels, swiftly closing the gap. Their ascent is further fueled by Chinese smartphone titans OPPO, Vivo, and Xiaomi. Additionally, domestic shifts prompted by governmental policies are positioning Chinese CIS companies like OmniVision, Galaxycore, and SmartSens to rally behind local production.

Power Discretes mainly encompass products like MOSFETs and IGBTs. Vanguard and HHGrace have been deeply involved in Power Discrete processes for some time, boasting a more comprehensive process platform and vehicle certification than many competitors. However, a wave of Chinese contenders, backed by national policies favoring EVs and solar initiatives, are ready to stake their claim, intensifying global competition in this sector. This includes mainstream foundries like HHGrace, SMIC, Nexchip, and CanSemi. Additionally, smaller Chinese IDMs and foundries, such as GTA and CRMicro, are also entering the competitive landscape. If China massively ramps up its production capacity, it will intensify global competition in Power Discrete manufacturing. The impact will not only spark price wars among local Chinese businesses but could also erode the order books and clientele of Taiwanese companies.

In a nutshell, while China actively courts both global and domestic IC designers to bolster its local manufacturing presence, the ensuing massive expansion could flood the global market with mature processes, potentially igniting a price war. TrendForce notes that as China’s mature process capacities continue to emerge, the localization trends for Driver IC, CIS/ISP, and Power Discretes will become more pronounced. Second and third-tier foundries with similar process platforms and capacities might face risks of client attrition and pricing pressures. Taiwan’s industry leaders, renowned for their specialty processes—UMC, PSMC, Vanguard to name a few—will find themselves in the eye of the storm. The battle ahead will hinge on technological prowess and efficient production yields.
