According to the new research report titled "Sapphire Substrate Market Forecast to 2028 - COVID-19 Impact and Global Analysis," published by The Insight Partners, the market is expected to reach US$ 884.26 million by 2028, registering a CAGR of 5.6% from 2022 to 2028.

In sapphire substrate market, Sapphire Epi wafers are thin-film substrates available in various sizes and orientations. They are used in LED, microelectronics, and ultra-high-speed integrated circuits (ICs). Their electrical properties make them a preferred substrate material for semiconductor fabrication. As LED lighting becomes the US$ 80 billion industry, the epitaxial wafers LEDs market will grow to US$ 4 billion in 2020 indirectly growing the sapphire substrate market size. Today, the majority of these epi-wafers are GaN-on-sapphire. Also, in the sapphire substrate market growth depends on, the sapphire wafer carriers which offer a stable carrier for processing GaAs and other semiconductors. Sapphire wafer carriers are durable and chemical and scratch resistant and can be used repeatedly. Owing to the sapphire's extreme hardness, it provides stronger and more durable carrier than quartz and other materials. In sapphire substrate market, the average price of sapphire wafer carriers ranges from US$ 500 to US$ 900.

The growing demand for silicon-on-sapphire microelectronic circuits has been propelling the sapphire substrate market share significantly. It is the way of developing a monocrystal Si film on sapphire wafers crystal face (1-102), known as the heterogeneous extension method. It then develops semiconductor devices on monocrystal Si film. It has the same thermal expansion coefficient as the monocrystalline Si. Sapphire usage for wafers has also helped in reducing the overall cost of larger wafers at relatively low rate. Currently in sapphire substrate market analysis, high quality GaN crystals can overgrow on sapphire wafer with the significant rise of advancement in technology. The (0001) sapphire surface has become the most ideal application of the substrate.

Sapphire substrate is increasingly used in LEDs, laser diodes, and RFIC applications, with LED accounting for over ~90%. Sapphire substrate is suitable for LED applications due to its high strength, high-temperature resistance, low dielectric loss, and good electrical insulation. It helps prevent LED lighting from stray currents, which are caused due to radiation from spreading to close circuit elements. The patterned sapphire substrate technology has become an effective way to improve the efficiency and reduce the cost of LEDs in the sapphire substrate market growth. Therefore, it is widely used in mid-power LEDs.

Gavish, San'an Optoelectronics, Monocrystal, Silian, Crystalwise Technology, and Rubicon Technology are among the prominent producers of LED sapphire substrates. As sapphire substrates are a key component for LEDs, general lightings continue to require substrate materials in the LED market. Thus, the increasing demand for sapphire substrates in LED applications boosts the sapphire substrate market.

The sapphire substrate market analysis is segmented on the basis of wafer diameter, application, and geography. Based on wafer diameter, the market is segmented into 2 inches, 4 inches, 6 inches, and others. By application, the sapphire substrate market is segmented into LED, RFIC application, laser diode, silicon on sapphire (SOS) IC, and others. On the basis of geography, the sapphire substrate market size is segmented into North America, Europe, Asia Pacific (APAC), the Middle East & Africa (MEA), and South America.

Key Findings of Study:

The global sapphire substrate market is divided into five regions-North America, Europe, Asia Pacific, the Middle East & Africa, and South America. The semiconductor sector in the US has maintained its leading global position in key future technologies, including artificial intelligence (AI) and quantum computing and sophisticated wireless networks, such as 5G. The semiconductor industry in the US, on the other hand, is confronted with several difficulties especially during the COVID-19 pandemic, which threw the US economy into disarray and disrupted global supply systems, creating major market instability in the short term. The escalating cost of innovation in semiconductor production and design, especially at the advanced fabrication processes, continues to be a problem. Advanced semiconductors enable higher industry investments in R&D to develop even more advanced semiconductors and enable new applications, leading to increased demand and sales revenue. For example, the cell phone evolution, was made possible by the ability to put low-power analog and radio frequency (RF) circuits onto wafers. Such semiconductor applications require sapphire substrate as their raw material, boosting the demand for the sapphire substrate in North America.

Asia Pacific dominates semiconductor manufacturing. Most of the world's major wafer design businesses now rely on manufacturers in Asia Pacific to manufacture semiconductor wafers, with South Korea and Taiwan playing a dominant role. TSMC and Samsung are the two most powerful manufacturers, controlling over 70% of the whole manufacturing market and, in recent years, becoming the exclusive providers of cutting-edge wafers. Semiconductor manufacturing requires a lot of money (tens of billions of dollars) and a lot of research. Taiwanese semiconductor wafers, in particular, account for more than half of the global total. Taiwan is continuously reinventing its processes to keep its dominance in the future, presenting the most sophisticated 3 nm technology, which will be implemented in the second half of 2022. The COVID-19 pandemic started in Asia, and because many component makers were based there, the pandemic immediately impacted the regional market. Many of these firms were forced to suspend manufacturing early in the outbreak, and this, combined with global travel restrictions, resulted in major supply shortages in the sapphire substrate market share.
