Amid a two-year recalibration in the smartphone and electronic component supply chain, inventory levels have rebounded to a healthy state. The infusion of new applications like AI and auto driving has fueled a comprehensive replenishment of consumer electronics inventory, propelling IC design with a surge in urgent and short orders.

Although wafer prices surged by over 40% during the pandemic, recent declines in utilization suggest an impending price reduction cycle to maintain operational rates, expected to lead to a reduction in IC design costs. Key players, boasting inventory turnover periods below a hundred days, are well-positioned for a potential upswing in demand, as reported by CTEE.

While most semiconductor companies are anticipated to experience declines in 2023, inventory levels have already tapered off. MediaTek boasts an inventory turnover period of just 89.11 days, with Realtek and ITE Tech at 96.77 and 84.11 days, respectively.

IC design companies emphasize the dominance of rush orders in the latter half of the year. Despite the uncertainty of economic visibility, confidence prevails regarding the new applications like AI, auto driving, and LEO(Low Earth Orbit) satellites, promising an upsurge in demand.

IC design companies also point out that the 3-5 year cycle of device replacement is imminent. The infusion of new AI applications and technological advancements in decision-making and workplace practices is expected to drive business demand. Positive developments, such as Microsoft discontinuing support for Windows 10, are anticipated to gain traction by 2024.

In the previous articles (China Strives to Break Through U.S. Restrictions in Mature Processes, Aiming for Over 30% Global Share by 2027 and China’s Wafer Fabs Hits 44 with Future Expansion 32, Mainly Targeting on The Mature Process) we explored the overall layout of Chinese wafer fab and developments in 12-inch and 8-inch wafer foundries. This article shifts to navigating the challenges of preventing oversupply while strategically pushing forward in the realm of mature processes.

Due to the counterattack of international giants in mature processes leads to fierce competition for orders, the recent surge in mature processes over the past two years in fact has brought pressure to Chinese wafer fabs. From the perspective of the industry chain, it may also cause industry overcapacity.

The popularity of mature processes can be traced back to its extensive application market, research and development of advanced processes approaching the limit of Moore’s Law.

No need to say it also reflects the regular operation of market dynamics. In the current economic downturn, the demand for automotive electronics and industrial control systems(ICS) is booming, with 80% of their demand falling under mature processes. As the AI trend rises, many high-end AI and computing chips in China cannot adopt advanced processes, prompting a reconsideration of design changes to use multiple mature process chips instead of a single high-end process chip. This not only ensures shipments but also indirectly increases the synchronous multiplier of mature process chips.

Can Specialty Processes Become a Blue Ocean for China?

With the emergence of new demands in downstream application scenarios, the variety of semiconductor products continues to increase. Industry insiders state that global foundries are competing to target mature process wafer foundries. In this context, Chinese wafer fabs should focus on creating differentiation.

Therefore, specialty processes are gradually gaining attention in the current development of wafer foundries. In comparison to advanced logic processes, specialty processes particularly emphasize the research, innovation, and application of new materials (SiC and GaN are currently popular), new structures, and new devices. Specialty processes highlight wafer processes with custom capabilities for special IP and diverse technological categories. This is considered an important development branch beyond Moore’s Law, which involves continually reducing the linewidth to enhance chip integration.

Specialty process product categories are extensive and can form a competitive advantage in specific areas. These mainly include embedded/independent non-volatile memory, power devices, analog and power management, sensors, and other process platforms.

Representative enterprises in China’s specialty process industry include SMIC, Huarun Microelectronics, and Huahong Group. These companies attach great importance to the development of specialty processes. To meet the differentiated demands for product functionality and performance in the market, enterprises continually research and innovate wafer manufacturing process technologies, evolving into differentiated manufacturing processes.

For example, Huahong Semiconductor’s specialty processes include power management, radio frequency, power devices, and other platforms, especially in wafer foundry for power devices; Huarun focuses on high-voltage power BCD, high-performance BCD, high-reliability BCD, high-precision analog, MEMS, and six major special power device simulation wafer foundry processes.

Major wafer foundries have always attached great importance to the development of specialty processes. TSMC’s specialty process is leading by far, while GlobalFoundries and UMC are also focusing on mature processes and specialty processes. It is not difficult to predict that there will be fewer and fewer participants chasing advanced processes in the future, and new entrants will compete for the market in specialty processes.

On August 7th, HuaHong Group officially went public on the Sci-Tech Innovation Board Market, Shanghai Stock Exchange (STAR Market, SSE). Combined with the return of SMIC to A-shares (China’s domestic shares) in the past two years and Nexchip’s listing in May, it brings together the three major players in China’s foundry sector on the STAR Market. Additionally, SMEC, closely linked to SMIC, also went public on the STAR Market without turning a profit. Overall, China’s foundry industry is steadily gaining strength.

As per TrendForce’s latest research, challenges in the economic outlook and ongoing inventory issues this year have led to a slowdown in demand. This is particularly noticeable in the automotive and industrial control, where inventory has been piling up after short-term fulfillment. Fabless and other IDM inventory digestion have faced severe restrictions. IDM foundries, launching new capacities, are consolidating outsourced orders and once again reducing orders to foundries. In 2024, given the expected unfavorable economic environment, the overall recovery of capacity utilization poses challenges.

While Chinese foundries have not been immune to these challenges, the losses have been mitigated thanks to the boost in China’s import substitution policies on semiconductors. According to TrendForce, the global ratio of mature (>28nm) to advanced (<16nm) processes is projected to hover around 7:3 from 2023 to 2027. 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.

Exploring China’s Wafer Foundries Landscape

According to TrendForce, excluding 7 temporarily suspended fabs, China currently operates 44 fabs (25 fabs in 12-inch, 4 fabs in 6-inch wafers, and 15 in 8-inch fabs and production lines), additionally, 22 fabs are under construction (15 fabs in 12-inch, and 8 fabs in 8-inch). In the future, SMIC, Nexchip, CXMT, and Silan plan to construct 10 fabs (9 fabs in 12-inch, and 1 fab in 8-inch). Overall, by the end of 2024, China aims to establish 32 large fabs, and all of them are about to focus on mature processes.

Reviewing the distribution of wafer foundries across China, the Yangtze Delta region hosts nearly half of the total, with significant concentrations in provinces like Shanghai, Wuxi, Beijing, Hefei, Chengdu, and Shenzhen.

Nearly 4.14 million wafer capacity in 12-inch will be ongoing per month in China until 2026

In terms of capacity, the statistics showed that China currently operates 31 fabs in 12-inch, including those under construction with fixed capacity for 12-inch. The total monthly capacity is approximately 1.189 million wafer capacity. Compared to the planned monthly capacity of 2.17 million wafer capacity, the capacity utilization of these fabs is close to 54.48%, still a significant room for expansion.

Considering construction and future planning, it is anticipated that China will add 24 fabs in 12-inch in the next five years, with a planned monthly capacity of 2.223 million wafer capacity. Assuming all planned 12-inch wafer foundries achieve full production, by the end of 2026, the total monthly capacity of 12-inch in China will exceed 4.14 million wafer capacity, marking a 248.19% increase compared to the current capacity utilization rate.

Mature process foundries are locked in a battle to uphold a 60% capacity utilization rate. Reports indicate that major players, including UMC, Vanguard International Semiconductor (VIS), and PSMC, are slashing prices significantly for the first quarter of the coming year to salvage their capacity utilization rates. This reduction, reaching double-digit percentages and up to 15% to 20% for project customers, stands out as the most extensive post-pandemic price cut, according to UDN News.

Post-Pandemic Price Challenges in Mature Process Foundries    

This pricing adjustment is pushing the prices of mature process foundries to a new low post-pandemic, affecting the profit margins and profitability trends of related companies. Industry sources disclose that only TSMC’s prices remain robust, with almost no exception for other foundries.

To rescue capacity utilization rates, companies are aggressively tweaking their quotes. A source from an IC design company privately reveals that foundries have notified them of slow-moving business in mature processes, resulting in a direct drop in capacity utilization rates. To ensure capacity utilization rates and market share, maintaining a certain level of production scale becomes imperative, prompting a substantial reduction in quotes.

Industry sources emphasize that despite recent indications of recovery in the PC and smartphone markets, clients remain cautious due to external factors such as inflation, especially given almost a year of inventory clearance. Companies, still on edge, fear slipping back into the challenges of inventory clearance and thus maintain a conservative approach to order placement.

Currently, the recovery in order placement strength is only about 30% to 40% of pre-pandemic levels, compelling wafer foundries to intensify their price cuts to prevent orders from being lost to competitors willing to lower prices, resulting in even lower capacity utilization.

It is evident that consumer IC demand for foundry services is low, and whom focusing on 8-inch mature process are the most affected. It is mainly due to excessive duplicate orders from integrated device manufacturers (IDMs) and IC design companies in the past, leading to inventory clearance for chips such as power management ICs, driver ICs, and microcontrollers (MCUs). Some products have even shifted to 12-inch wafers, keeping the capacity utilization rates of 8-inch foundries at a low level.

Navigate Semiconductor Shifts in TSMC, UMC, VIS, and PSMC

Industry sources note that TSMC is bolstered by advanced processes, enabling them to bundle them with mature processes for sale. Moreover, TSMC’s pricing strategy for mature processes has not surged as dramatically as that of other related companies, making it more acceptable to customers.

As for UMC, the company anticipates a drop in capacity utilization rates from 67% in the last quarter to 60% to 63% in this quarter, reaching a single-season low in recent years. Due to the continuous adjustment of capacity utilization rates, the gross profit margin will drop from 35.9% last quarter to 31% to 33%, reverting to levels seen at the beginning of the pandemic in 2021.

In response to pricing issues, UMC stated that, as mentioned in a recent earnings call, there will indeed be a significant decrease in the 8-inch, but there will be no adjustments for the 12-inch. Supply chain sources reveal that UMC has reportedly offered a 5% concession, aiming to consolidate order momentum with major clients this quarter. Considering the anticipated weak demand in the first quarter of next year and to attract more order placements, UMC plans to expand the price reduction to double-digit percentages.

According to the supply chain, VIS is expected to see a price reduction of up to 5% in the second half of the year. Large-volume clients may even secure a 10% discount, with a further decrease expected in the first quarter of next year, ranging from single to double-digit percentages. The company’s management previously mentioned at a conference call that, in response to intense price competition, short-term flexible adjustments are anticipated.

Similarly impacted by conservative customer order placements, PSMC reported losses in the third quarter, with capacity utilization rates hovering around 60%. It is reported that PSMC is also gearing up to implement price reduction measures to enhance capacity utilization rates.

In TrendForce’s latest solar energy pricing, it is revealed that upstream polysilicon and wafer transactions have reached a standstill, while downstream cell and module prices continue to decline.

• Polysilicon

Polysilicon prices continue to decline throughout the week. The mainstream concluded price for mono recharge polysilicon is RMB 70/KG, while mono dense polysilicon is priced at RMB 68/KG and N-type polysilicon is currently priced at RMB 75/KG.

In terms of trading, this week has shown a slight improvement compared to the stagnation of the previous week. Some small orders have been placed, but the majority of companies are still in the negotiation process. Additionally, there are ongoing discussions about transaction prices for polysilicon and crystal pulling.

Examining the price trends, there’s a notable divergence between leading manufacturers and second-tier manufacturers, with the current prices approaching the cost threshold for the latter and older capacity.

When we analyze the supply and demand dynamics, it becomes evident that as polysilicon prices continue to decline, downstream manufacturers are considering production cuts, and new production capacity might face the challenge of running at a loss right after starting operations.

Moreover, considering the projected oversupply in the future and the potential for prices to hit rock bottom, some manufacturers have realized that the profits from new production capacity may differ significantly from their expectations, prompting them to adjust their production schedules.

However, in the short term, polysilicon output is showing a month-on-month growth trend this quarter. As downstream demand decreases, polysilicon prices will likely continue to face pressure. Overall, this week has seen a decline in quoted polysilicon prices, and the price gap between N-type and P-type polysilicon continues to narrow.

• Wafer

The prices of wafer have still reduced throughout the week. The mainstream concluded price for M10 wafer is RMB 2.30/Pc, while G12 wafer is priced at RMB 3.30/Pc. The current cell prices are causing significant losses in the cell business, leading to a substantial reduction in activation rates.

The overall market turnover is currently sluggish. Additionally, the quoted prices only reflect the trend of declining wafer prices and may not accurately represent the actual transaction prices for spot goods.

On the supply side, wafer prices have continued to decline over the past two weeks. If the prices of different types of wafers keep dropping, manufacturers may find themselves in a situation where their costs exceed their selling prices.

Consequently, wafer production schedules have seen a significant reduction, forcing some second and third-tier manufacturers to maintain OEM business for meager profits. The current wafer inventory level has decreased to 1.9-2.1 billion pieces, and there are indications that prices are reaching a bottom in the market.

On the demand side, downstream cell manufacturers are gradually reducing their production schedules, and inventory issues have not been effectively resolved. As a result, cell manufacturers are becoming more cautious when it comes to purchasing wafers. This week, wafer prices have continued to decline, but the rate of decline will narrow with cost support.

However, considering the price pressure imposed by downstream consumers, their high inventory levels, and other factors, wafer prices have yet to stabilize and are likely to continue falling in the future.

• Cell

Cell prices have still declined this week. The mainstream concluded price for M10 cell is RMB 0.48/W, while G12 cell is priced at RMB 0.52/W. The price of M10 mono TOPCon cell is RMB 0.49/W.

On the supply side, current cell inventory has remained high for more than seven days. Consequently, facing pressure from both the elevated inventory levels and downstream module manufacturers, cell prices have experienced a decline.

The current price of M10 P-type cells stands at 0.48 yuan per watt, which is approaching the production cost of leading integrated manufacturers. The reduction in cell production is the current scenario.

However, the shipment pressures haven’t been alleviated, and the price gap between N-type and P-type cells has narrowed, putting both types at risk of operating at a loss due to costs exceeding their prices. On the demand side, the domestic peak season for centralized cell procurement has concluded, and there has been no significant uptick in demand in overseas markets or the distributed PV sector.

As a result, the demand for cells has weakened. With module prices also under pressure, module manufacturers are inclined to push down cell prices. Although there has been some improvement in the rate of decline for cells this week, the accumulation of cell inventory, falling upstream material prices, and sluggish downstream demand continue to exert constant pressure on cell prices.

• Module

Module prices have gone down slightly throughout the week. The mainstream concluded price for 182mm facial mono PERC module is RMB 1.08/W, 210mm facial mono PERC module is priced at RMB 1.11/W, 182mm bifacial glass PERC module at RMB 1.09/W, and 210mm bifacial glass PERC module at RMB 1.12/W.

On the supply side, module prices are persistently decreasing and have come close to the cost price of integrated manufacturers. Specialized module manufacturers, in response to module prices falling below their cost, have had to reduce their production rates to avoid losses. This is evident from the reduced demand for various auxiliary materials associated with module production.

On the demand side, the primary driver of demand continues to be large domestic projects, whereas overseas demand has not shown any significant increase. The overseas market is still working through its high inventory. In domestic bidding projects, there’s a noticeable shift toward an increased proportion of N-type modules, indicating a faster transition in demand toward N-type technologies.

In the third round of centralized procurement for PV modules by Huadian Group, the quoted price stands at 0.9933 yuan per watt. In the same month, the bidding price for modules in the centralized procurement tender by CHN Energy is 0.945 yuan per watt, marking a record low within a single month.

This price trend underscores the inevitable intense competition within the module sector, as excess production capacity is evident throughout the entire industry chain. This week, module prices have continued their descent. In summary, it’s probable that module prices will remain volatile in the future, especially considering that bidding prices for modules are swiftly approaching the 1 yuan mark.
