Small-Dimension Wafer Market Estimated to Achieve Revenue of $5.4 Billion by 2025

Small-Dimension Wafer Market Estimated to Achieve Revenue of $5.4 Billion by 2025

Yole, a market research & strategy consulting company, has published a new research report on the Small-Wafer Market to point out the latest technical innovations and underline business opportunities. By Small Wafers they mean semiconductor wafers that measure 1-6 Inches in diameter. According to the report, this industry is forecast to grow at a CAGR of 1.8% from 2019 and 2025 in with estimated revenues of US $5.4 Billion in 2025.

This report shows that Non-Si wafers show moderate to strong CAGRs from 2019 - 2025. For example, SiC is expected to show a CAGR of 19.5%, with revenues estimated at US $712 Million in 2025. Si on the other hand will exhibit a moderate negative CAGR, of -3.3% over the same period for sub-6’’ Si wafers. This negative CAGR is a result of most power and RF applications transitioning to 8’’ or even 12’’ wafers.

The 6” and Below: Small-Dimension Wafer Market Trends report provides detailed analysis of the small-dimension wafer market by material, application, and diameter. It also describes the key benefits, added value, and drivers for using small-dimension wafers in the semiconductor industry. Yole’s report delivers a relevant overview of the market trends and forecasts, supply chain, key players, and technology trends. The analysts had the opportunity to discuss the ecosystem, with a focus on China and Russia. At the end, this study they provide a snapshot dedicated to the related equipment market and fabs as well as the emerging wafer reclaim industry.

Yole’s analysts try to answer the following questions from the 6’’-and-below wafer diameter industry:

  • What are the economic and technological challenges of the small-wafers industry?
  • What are the key drivers?
  • Who are the key suppliers to watch, and what innovative technologies are they working on?

According to Yole’s semiconductor manufacturing team, this sub-6” market strength can be linked to a “good enough” device performance/fabrication cost-per-die ratio so that large CAPEX and risky process changes cannot always be fully justified. “This “good enough” concept is important and is a strong driver in the use of small-dimension wafers,” explains Vishnu Kumaresan, PhD., Technology & Market analyst, Semiconductor Manufacturing at Yole.

In parallel, Yole points out strong market drivers for each material and related applications. For example, SiC for power electronics applications is currently getting huge investments. Almost all leading power electronics and compound semiconductor companies are deeply involved in the development of SiC-based solutions.

"In the 2019-2020 period, there has been significant news on the SiC device and module business in terms of partnerships and acquisitions”, explains Ezgi Dogmus, PhD. Technology & Market Analyst, Compound Semiconductor & Emerging Materials at Yole.” This clearly validates the SiC substrate and device manufacturer’s desire to climb up the value chain to benefit from growing business opportunities at the module level.”

Yole’s semiconductor manufacturing team is working with Yole’s compound semiconductor analysts to combine their expertise and get a clear understanding of the market evolution and the impact of the adoption of emerging technologies. SiC technologies and related applications are followed by the compound semiconductor team through a dedicated Quarterly Market Monitor.

InP and datacom applications are also a good example to highlight the added value of small dimensions wafers. The case of sapphire is particularly interesting, and the competitive landscape has changed tremendously after a price collapse, with only a handful of players serving a high-volume yet saturated LED market. However, the microLED market could significantly increase demand by 2023, especially in the 6’’ range.

Ahmed Ben Slimane, PhD., Technology & Market Analyst, Compound Semiconductors at Yole, stated that MicroLEDs could also proper the GaAs wafer market, particularly for red pixels – indeed the GaAs growth is significantly boosted by photonics applications, with GaAs VCSEL technology strongly dominating this market due to the high volume demand for consumer 3D sensing applications, causing GaAs to grow with a CAGR of no less than 8% between 2019 and 2025. Overall, new applications and needs are driving evolutions in wafer diameters, by material and by application.

The GaAs market is studied in the Quarterly Market Monitor mentioned above.

Less known is the existence of a market for depreciated fabs, which also represent tremendous opportunities to produce devices at low cost for any volume. For example, there is still significant demand for 6’’ Si wafers in standard power IGBT and MOSFET devices. Higher-end devices can then be fabricated in brand-new fabs, for example, Robert Bosch and Infineon Technologies in the power electronics industry, in the Si 300 mm range, which is also a way to secure future supplies and assert one’s dominance in the market.

According to Vishnu Kumaresan from Yole, a similar trend is at play in the SiC wafer manufacturing industry, with some major players moving quickly to 8’’ wafer diameter and securing their supply chain while leaving behind 6’’ (and even more so 4’’) wafer processing capacities. With the increased use of non-Si substrates, more and more players are offering specific processing equipment for a given material and/or are proposing equipment which can adapt to different materials and diameters, including 4’’ and 6’’. This equipment can be astutely used in fully depreciated sub-6’’ Si wafer fabs, creating opportunities for players small and large to offer a highly competitive device fabrication cost.
