According to the new research report titled "Silicon EPI Wafer Market Forecast to 2028 - COVID-19 Impact and Global Analysis," published by The Insight Partners, the market is expected to reach US$ 4,997.32 million by 2028, registering a CAGR of 8.8% from 2022 to 2028.

An EPI wafer, or epitaxial wafer, is formed by depositing a layer of single crystal silicon epitaxially onto a single crystal silicon wafer. This type of wafer is useful for controlling doping profiles that are challenging to manage using traditional methods such as diffusion and ion implantation. Epitaxial wafers made of silicon are widely used in the production of a broad range of semiconductor devices, including those used in consumer, industrial, military, and space electronics. They are used in the substrates of bipolar and metal-oxide-semiconductor (MOS) integrated circuits (ICs), as well as in diode and transistor components.

Epiel is a company that specializes in manufacturing silicon epitaxial wafers and provides epitaxial services for the semiconductor industry. The company offers customized silicon epitaxial wafers ranging in size from 3" (76 mm) to 8" (200 mm) for various microelectronics applications, including integrated circuits, discrete power devices, and sensors. In 2020, a US-based start-up, Qromis, entered into a licensing agreement with Japan's Shin-Etsu Chemical to manufacture substrates and epitaxial wafers for GaN power/RF electronics, LED devices, and other devices. Qromis has already made 6- and 8-inch GaN-ready QST substrates available, as well as 6- and 8-inch "templates" with 5- and 10-micron GaN layers. It is also developing 900V and 1200V GaN HEMT EPI wafers, along with 200V and 650V GaN HEMT EPI wafers based on six- and eight-inch QST substrates for electronic instruments. Qromis intends to establish a second production facility for QST substrates and GaN-on-QST epitaxy wafers due to the projected growth in the silicon EPI wafer market and the positive outlook for GaN adoption.

The market for silicon EPI wafers is categorized based on wafer size, application, industry, type, and geography. The wafer size segment includes 6 inch, 8 inch, 12 inch, and other sizes. The application segment includes LED, power semiconductor, and MEMS-based devices. The end-user segment includes consumer electronics, automotive, healthcare, aerospace and defense, and others. The type segment is bifurcated into heteroepitaxy and homoepitaxy. Finally, based on geography, the market is segmented into North America, Europe, APAC, the Middle East & Africa, and South America.

Key Findings of Silicon EPI Wafer Market Study:

The study on the global silicon EPI wafer market is divided into five key regions, namely North America, Europe, Asia Pacific (APAC), the Middle East & Africa (MEA), and South America (SAM). The APAC region dominated the market with a 54.0% share, which can be attributed to the presence of several leading consumer electronics manufacturers in the region, including Samsung Electronics, Hon Hai Precision, Sony, Panasonic, Lenovo Group, Mitsubishi Electric, and Toshiba. The outbreak of COVID-19 had an immediate impact on the regional semiconductor industry market, which affected the growth of the silicon EPI wafer market as well. The pandemic caused several firms to halt their manufacturing operations early on, leading to significant supply shortages in the region due to travel restrictions. In addition, the successful implementation of energy policies is contingent upon stable political conditions and administrative efficiency. Therefore, political stability and administrative efficiency can play a crucial role in increasing policy credibility and enabling a successful transition to renewable energy. North America held a 23.9% market share, followed by Europe, the Middle East & Africa, and South America.

The conflict between Russia and Ukraine may potentially result in shortages of chips, with the immediate risk being the availability of raw materials such as neon and palladium, which are used in the production of semiconductors. Russia is a major supplier of palladium, accounting for over 40% of the global supply, while Ukraine produces 70% of the world's neon. Semiconductor manufacturers usually keep up to six months' worth of neon in stock, and if they run out, they may be unable to produce semiconductors. The short-term impact on semiconductor production is expected to be moderate, but in the long run, chipmakers and consumers may face significant adverse effects on the cost and supply of raw materials.
