According to TrendForce’s “2023 GaN Power Semiconductor Market Analysis Report – Part 1,” the global GaN power device market is projected to grow from $180 million in 2022 to $1.33 billion in 2026, with a compound annual growth rate of 65%.

The development of the GaN power device market is primarily driven by consumer electronics, with a focus on fast chargers as the core application. Other consumer electronic scenarios include Class D audio and wireless charging.

However, many manufacturers have already shifted their focus to the industrial market, with data centers being a key application. ChatGPT has sparked a wave of AI cloud server deployment, and GaN technology will help data centers reduce operating costs and improve server efficiency.

Simultaneously, the automotive market is also gaining attention, as OEMs and Tier 1 suppliers recognize the potential of GaN. It is expected that by around 2025, GaN will gradually penetrate low-power onboard chargers (OBC) and DC-DC converters. Looking further ahead to 2030, OEMs may consider incorporating GaN technology into traction inverters.

In terms of market competition, based on GaN power device business revenue, Power Integrations ranked first in 2022. The company has been leading the high-voltage market’s development since 2018, and its excellent GaN integrated solutions have gained wide market recognition. Other leading manufacturers include Navitas, Innosic, EPC, GaN Systems, and Transphorm.

Additionally, the industry paid attention to the acquisition of GaN Systems by Infineon. According to TrendForce’s statistics, the combined market share of both companies was approximately 15% in 2022.

Turning to the supply chain, as mentioned earlier, the development of the GaN power device market will be driven by consumer electronics for a long time. Therefore, the industry must pursue scale and low cost, necessitating the expansion of wafer sizes. Currently, mainstream GaN power wafers still rely on 6-inch silicon substrates, with only Innosic, X-FAB, and VIS offering 8-inch options. With a positive outlook for the long-term development of the GaN power market, several wafer manufacturers have announced plans to shift to 8-inch wafers in the coming years, including Infineon, STMicroelectronics, TSMC, and others.

Furthermore, Samsung recently announced its entry into the 8-inch market and plans to provide foundry services starting from 2025, a development worth industry attention.

The global automotive industry is pouring billions of dollars into SiC semiconductors, hoping that they could be key to transforming vehicle power systems. This shift is rapidly changing the supply chain at all levels, from components to modules.

In the previous piece “SiC vs. Silicon Debate: Will the Winner Take All?,” we explored SiC’s unique physical properties. Its ability to facilitate high-frequency fast charging, increase range, and reduce vehicle weight has made it increasingly popular in the market of electric vehicles (EVs).

Research from TrendForce shows that the main inverter has become the first area for a substantial penetration of SiC modules. In 2022, nearly 90% of all SiC usage in conventional vehicles was in main inverters. As demand grows for longer range and quicker charging times, we’re seeing a shift in vehicle voltage platforms from 400V to 800V. This evolution makes SiC a strategic focus for automotive OEMs, likely making it a standard component in main inverters in the future.

However, it is common for now that SiC power component suppliers fail to meet capacity and yield expectations – a challenge that directly affects car production schedules. This has led to a struggle for SiC capacity that is impacting the entire market segment.

Device Level: Burgeoning Strategic Alliances

Given the long-term scarcity of SiC components, leading OEMs and Tier 1 companies are vying to forge strategic partnerships or joint ventures with key SiC semiconductor suppliers, aiming to secure a steady supply of SiC.

In terms of technology, Planar SiC MOSFETs currently offer more mature reliability guarantees. However, the future appears to lie in Trench technology due to its cost and performance advantages.

Infineon and ROHM are leaders in this technology, while Planar manufacturers like STM, Wolfspeed, and On Semi are gradually transitioning to this new structure in their next-generation products. The pace at which customers embrace this new technology is a trend to watch closely.

Module Level: Highly-customized Solutions

When it comes to key main inverter component modules, more automakers prefer to define their own SiC modules – they prefer semiconductor suppliers to provide only the bare die, allowing chips from various suppliers to be compatible with their custom packaging modules for supply stability.

For instance, Tesla’s TPAK SiC MOSFET module as a model case for achieving high design flexibility. The module employs multi-tube parallelism, allowing different numbers of TPAKs to be paralleled in the same package based on the power level in the EV drive system. The bare dies for each TPAK can be purchased from different suppliers and allow cross-material platform use (Si IGBT, SiC MOSFET, GaN HEMT), establishing a diversified supply ecosystem.

China’s Deep Dive into SiC Module Design

In the vibrant Chinese market, automakers are accelerating the investment in SiC power modules, and are collaborating with domestic packaging factories and international IDMs to build technical barriers.

• Li Auto has collaborated with San’an Semiconductor to jointly establish a SiC power module packaging production line, expected to go into production in 2024. 
• NIO is developing its own motor inverters and has signed a long-term supply agreement with SiC device suppliers like ON Semi.
• Great Wall Motor, amidst its transformation, has also focused on SiC technology as a key strategy. Not only have they set up their own packaging production line, but they’ve also tied up with SiC substrate manufacturers by investing in Tongguang Semiconductor.

Clearly, the rising demand for SiC is redrawing the map of the value chain. We anticipate an increase in automakers and Tier 1 companies creating their unique SiC power modules tailored for 800-900V high-voltage platforms. This push will likely catalyze an influx of innovative product solutions by 2025, thereby unlocking significant market potential and ushering in a comprehensive era of EVs.

Onsemi, a semiconductor manufacturer, announced at the end of April that it had signed a Long-Term Supply Agreement for SiC power components with Zeekr, a subsidiary of Geely Auto Group. Geely Automotive will use Onsemi’s EliteSiC power components to optimize energy conversion efficiency in its electric drive system. This move signals Onsemi’s aggressive expansion in the automotive SiC market, catching up to leading manufacturers STMicroelectronics and Infineon.

In the SiC semiconductor market for electric vehicles, STMicroelectronics and Infineon have maintained their market leadership by entering the market early, while Wolfspeed and ROHM have gained traction through their vertical integration technology for SiC. On the other hand, Onsemi still lags behind in terms of market share for SiC power semiconductors, even though it acquired GT Advanced Technologies in 2021 and mastered the most difficult wafer growth and production equipment technology in SiC manufacturing. Before 2023, Onsemi was only used in small and medium-sized vehicle models such as NIO and Lucid.

However, Onsemi’s benefits begin to materialize in 2023, thanks to the industry maturity built by early players such as Infineon and STM, combined with Onsemi’s early deployment of SiC-related technology. Onsemi’s SiC product EliteSiC has obtained LTSA from Zeekr, BMW, Hyundai and Volkswagen in the form of discrete and modules. Its CEO, Hassane El-Khoury, has stated that the SiC business will generate $4 billion in revenue over the next three years compared to the total revenue for the 2022 SiC market of approximately $1.1 billion. These factors have made Onsemi the most talked-about semiconductor company in the SiC market this year.

However, the intense competition in the SiC market will test the endurance of resource input sustainability. The rapid growth in SiC demand over the past five years is mainly due to high battery costs and the development of energy density having reached its limit. Car manufacturers have switched to using SiC chips in their electronic components to increase driving range without increasing the number of batteries.

As a result, car manufacturers are aggressively pushing semiconductor companies to accelerate their research and development of SiC technology. This has resulted in a significant reduction in R&D time, but also an increase in R&D costs. Coupled with the impact of intense market competition on profits, the ability to sustain R&D resource input and overall profitability performance will be the key indicators of semiconductor companies’ competitiveness.

Onsemi has successfully improved its profitability performance by streamlining its product lines over the past few years, ranking at the top with a 49% gross margin, according to the financial reports of various semiconductor companies in 2022. This profitability performance allows Onsemi to meet car manufacturers’ cost requirements and secure orders, thereby achieving economies of scale in SiC product growth.

However, in terms of R&D costs as a percentage of revenue, Onsemi ranks last at 7%, compared to its main competitors Wolfspeed (26%), Infineon (13%), STM (12%), and ROHM (8%). With semiconductor companies investing more in technologies such as reducing on-resistance and improving yield rates, how to maintain a balance between profitability performance and resource expenditure while achieving revenue goals through intense market competition will be an important challenge for Onsemi after securing orders from car manufacturers.

Due to material shortages caused by insufficient semiconductor supply, to date, power management IC (PMIC) prices remain on an upward trend, according to TrendForce’s latest investigations. Average selling price (ASP) for 1H22 is forecast to increase by nearly 10%, reaching a record six year high.

In terms of the global supply chain, in addition to the production capacity of major IDM manufacturers including TI, Infineon, ADI, STMicroelectronics, NXP, ON Semiconductor, Renesas, Microchip, ROHM (Maxim has been acquired by ADI and Dialog by Renesas), IC design houses such as Qualcomm and MediaTek (MTK) have obtained a certain level of production capacity from foundries. Of these, TI is in a leadership position and the aforementioned companies possess a combined market share of over 80%.

In terms of product structure, unrelenting demand from the consumer electronics, telecommunications, industrial control systems, and automotive end-user sectors and product innovation driven by industrial transformation will push a dramatic increase in global market demand for PMICs. The largest application for PMICs is consumer electronic products and there are near term rumblings in demand for notebooks, Chromebooks, smartphones, and televisions. In addition, restocking impetus for a small number of structurally simple items such as low drop-out regulators (LDO) has encountered a real slowdown. However, since the demand placed on PMICs by electronic products is a structural increase, certain models are still experiencing shortages. Qualcomm and MTK are limited by a shortage of mature production capacity on the foundry end, even resulting in a tightening of inventory for PMICs earmarked for self-use.

Furthermore, recovery in the automotive market and rapid growth in electric vehicles, automotive electronics, and advanced driver-assistance systems (ADAS) have increased demand in power source control and management and charging technology. In addition, automotive-use ICs are required to pass a number of inspections and must guarantee consistency and a zero failure rate. Currently, IDM companies’ automotive IC order backlog stretches until the end of 2022. Due to factors such as production running at full capacity and a shortage of raw materials, PMIC suppliers have currently announced longer lead times with consumer electronic IC lead times increasing to 12~26 weeks, automotive IC lead times reaching 40~52 weeks, and a cessation of orders for certain exclusive production models.

TrendForce expects 4Q21 demand for PMICs to remain strong with shortages in overall production capacity. Led by IDM companies, PMIC pricing will remain high. Despite variables related to the pandemic and the difficulties of greatly increasing 8 inch wafer production capacity, TI’s new fab RFAB2 will begin mass production in 2H22. In addition, due to the plans of foundries to carry forward a portion of 8 inch wafer PMIC manufacturing to 12 inch, there is a high likelihood of a moderation in PMIC shortages. However, close attention must still be paid to changes in future market supply.

The analog IC industry is one with a long history of development and product adoption across various applications. Annual analog IC revenue reached US$53.9 billion in 2020. As the spread of the COVID-19 pandemic is gradually brought under control in China and the US this year, their domestic demand for telecom, automotive, industrial, and consumer electronics products has also kept growing, in turn generating strong demand for analog ICs. TrendForce therefore expects IC revenue for 2021 to reach US67.9 billion, a 22.1% YoY increase.

More specifically, analog IC demand from the automotive market is expected to undergo remarkable growth this year, primarily due to the recovery of the global automotive market and the continued trend towards automotive electrification as commercial opportunities from ADAS, EV, and automotive electronics enter a period of rapid growth. In response to demand from automakers and the auto market, various major IDMs have been placing a heavy emphasis on automotive analog IC development. Led by Infineon, NXP, Renesas, TI, and STM, the automotive IC market is expected to experience a 24.6% growth in 2021.

What is an analog IC?

The analog IC is an indispensable component in electronic devices. These chips can be divided into two categories according to their functions: general purpose analog IC and application specific analog IC. The former category encompasses amplifiers/comparators (signal conditioning), signal conversion, interface, and power management (general purpose). In sum, general purpose analog ICs are characterized by their low costs, single purpose, and universal compatibility.

Application specific analog ICs, on the other hand, encompass such use cases as consumer, computer, communications, automotive, and industrial/others. This product category refers to analog ICs that are designed and manufactured in accordance with electrical systems specified by the client. Compared to digital ICs, analog ICs are much more diverse in terms of product type, less costly, and more stable, while also having longer lifecycles.

The current state of the top three analog IC manufacturers

Almost all major analog IC suppliers are IDMs with long histories. In particular, longtime market leader Texas Instruments once against took pole position in the ranking of analog IC suppliers by revenue last year. With a range of analog ICs that includes more than 80,000 products, Texas Instruments possessed a 19% market share. The company is expected to maintain its dominance in 2021 thanks to its diverse product lines, high market acceptance, and high volume of client orders.

Infineon, which took second place on the ranking, registered a 19% YoY revenue growth on the back of its expansion into automotive and power management markets. Third-ranked STMicroelectronics benefitted from rising sales of its analog, MEMS, and sensor product portfolios. TrendForce expects Infineon and STMicroelectronics to continue their upward trajectories throughout 2021.

Whereas China is the largest market for analog ICs, the analog IC industry will see the highest growth in the US

China is expected to account for 42% of analog IC sales, the highest among all regions in 2021, with the consumer electronics segment comprising most of these transactions. However, the US is expected to undergo the highest growth in terms of analog IC sales with a US$10.6 billion revenue in 2021, a 25% YoY growth. This performance can mostly be attributed to the fact that the US economy has been recovering in the post-pandemic era owing to increasing purchases in the consumer electronics, telecom, and automotive markets.

Furthermore, the US government has been pushing for infrastructure developments with a focus on transportation, networking, and electricity generation, leading to expanded procurement of analog ICs used in these applications. As the markets welcomes the arrival of the traditional peak season for analog IC procurement in 2H21, growth in the US market will likely persist as well.
