The semi-insulating silicon carbide wafer market was USD 367.8 million in 2021 and is projected to grow from USD 429.3 million in 2022 to USD 1,460.1 million by 2029, at a CAGR of 19.1 %. Based on our analysis, global market exhibited a decline of 12.1 % in 2020 as compared to 2019. The global COVID-19 pandemic has been unprecedented and staggering, with Semi-Insulating Silicon Carbide Wafer experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels.

SiC wafer is a semiconductor material made by the combination of silicon and carbon. SiC wafer has characteristics such as insulation material, semiconductor, thermal management materials, and high-temperature resistance. It is made by melting raw materials such as petroleum coke, quartz sand, and sawdust. It can be used for LED lighting devices, microwave devices, power electronic devices, and in refrigerator devices. It is a semiconductor material to make power devices. Nowadays, a semi-insulating silicon carbide wafer market growth is propelled due to its application 5G communication networks and electric vehicles to provide high power, high voltage, and high-frequency devices.

4 Inch SiC Wafer and 6 Inch SiC Wafer are the two types of Silicon Carbide Wafer. 4 Inch SiC wafer has characteristics such as insulation material, has superior electronic properties such as resistance to corrosion, erosion, and oxidation. They are used in electronic and LED devices. 6 Inch SiC wafer has excellent heat resistive properties, high thermal capacity, high speed wideband, and efficiency. It is used in automobiles for power transmissions and high-speed trains.


Problems Associated with Manufacturing and Raw Material Procurement has Increased Market Hindrance

The COVID-19 pandemic has disrupted economies across the globe. Due to this reason, developed as well as underdeveloped countries have faced a setback. Also, the market size is curbing and is facing challenges in maintaining the global economy across several sectors. Due to volatility in procurement of raw materials and limitations pertaining to cross border trade of these materials during the pandemic has impacted the sales of semiconductor materials and the supply chain of silicon carbide wafers. During the pandemic, Radio frequency (RF) chip makers such as Skyworks, and Qorvo in the U.S. saw a reduction in demand by 6% in 1st quarter of 2020. However, the silicon carbide wafer industry continued to maintain a leadership position in the semiconductor technologies that is crucial for various other sectors like the automotive & aerospace industries. Although the lockdown amidst CoVID-19 resulted in short-term challenges, it has also shaped the long-term opportunities for SiC wafers in consumer electronics and the automotive industry.

Deployment of Sic Wafer in Telecommunication Industry to Build 5G Network Aiding the Market

The telecom companies are advancing toward building high-speed 5G networks around the globe, which has increased the requirement for power semiconductors. For Instance, SK Siltron plans to make significant investments and expand its SiC-related facilities within five years to meet the growing demand for SiC-based power semiconductors for 5th generation communication equipment and electric vehicles. Additionally, due to SiC wafer’s high hardness, heat resistance, and ability to sustain high voltages they are commonly used to produce power semiconductors for 5G networks. Initially, the chipmakers were inclined towards using GaN to make power semiconductors. Further, the recent trend of using GaN on SiC offers superior thermal conductivity along with the high power density capabilities of GaN and low RF losses of SiC. These semiconductors that use SiC and GaN as the main material are the third-generation semiconductors and they are characterized by high- temperature resisitance, a wide energy gap, and high power density, which are ideal for building 5G infrastructure.


Hefty Investment in R&D & SiC Wafers Production Will likely to Accelerate Product Demand

There has been an increasing demand for SiC wafers due to their adoption in electric vehicles and fifth-generation telecommunication devices. In order to meet this increasing demand, companies are investing heavily in building state-of-the-art manufacturing facilities. For instance, Wolfspeed, a wideband semiconductor company, has announced to invest USD 1 billion in a SiC production manufacturing plant that will increase its wafer fabrication capacity by up to 30 folds as a part of its long-term growth strategy.                                                  

Furthermore, the manufacturing process of SiC is considered to be complex and costly owing to polytypism crystal structure and extreme thermodynamic properties. Therefore major players are making huge spending on Research & Development to introduce innovative manufacturing process and pace up production rate which is enhancing the market growth.


High Cost and Complex Manufacturing Process Limits Market Growth

Silicon carbide wafers are kind of single crystal wafers molded by cutting, grinding, cleaning, polishing, & other processes of silicon carbide crystals, but owing to its hardness and fragility, SiC needs more energy, higher temperature, and more time for crystallization and processing. Furthermore, the high transparency and refractive index of ‘4H-SiC’ (the most widely used SiC) makes it difficult to examine the material for a surface defect that could affect final component yield or epitaxial growth.

Moreover, even though SiC is the hardest material, it is very brittle, making it difficult to produce small components used in semiconductors. By virtue of all these reasons, the cost of SiC wafers is 3 times the cost of silicon wafers of the same rating.


By Type Analysis

6 Inch SiC Wafer to Hold a Significant Market Share Owing to Its Rising Demand in EV Sector

In terms of type, the market is classified into 4 Inch SiC Wafer and 6 Inch SiC Wafer.
