Silicon Carbide Substrate: The Future of Electronics

Silicon Carbide Substrate: The Future of Electronics

I am asked a lot, “What’s the secret to creating high performance devices that can withstand the demands of modern technology?” since electronics is my area of expertise.

“Silicon carbide substrate” is my go-to answer in every situation. In this article, we will discuss why SIC substrates are the best of electronic innovation and look at their uses, advantages, and production process.


Because of its high breakdown voltage, thermal conductivity, and radiation resistance, SiC is the ideal material to use when creating such devices that can endure hostile environments.

Silicon carbide substrate has given electronics manufacturers a powerful new tool for making better circuits.

Is there anything unique about SiC substrate that could improve the efficiency of your next project? Now, we will examine these aspects.

What Are Silicon Carbide Substrates?

A substrate made of silicon carbide is the result of combining carbon with silicon. Because of this blend, they have a rare set of characteristics that are in great demand in the electronics market.

Wafers, plates, sheets, and so forth are just a few of economical parts available for SiC substrates, which are tailored to unique needs because of its extensive customization capabilities.

Advantages of Silicon Carbide Substrates

Electronics manufacturers laud SiC substrates for a number of reasons:

Firstly, despite being functional at elevated temperatures, SiC substrates offer the benefit of rapid heat transfer because of their high thermal conductivity.

Secondly, because of their high breakdown voltage, these components are well-suited for use in power applications.

Thirdly, because of their resistance to external radiation, SiC substrates are ideal for use in spacecraft and other space-related applications.

Fourthly, these materials are resistant to a wide range of chemicals without causing corrosion.

Fifthly, Silicon is completely unaffected by sudden fluctuations in temperature and has high temperature stability.

Applications of Silicon Carbide Substrates

Silicon carbide substrates are very adaptable and are used in many demanding industries, including:

Power Electronics: The exploitation of SiC substrate hinges on the power components that includes: power MOSFETs, diodes and IGTs (Insulated Gate Bipolar Transistors). As they can work at high temperatures as well as voltages, power inverters and converters are more efficient, and thereby, have less energy wastage. 

RF Equipment: Due to its electrically non-conductive properties and high thermal conductivity, SiC is a viable option for RF devices. The efficiency and high temperature capabilities of SiC make it suitable for RF energy applications, where it can help in more efficient transmission of power and in applications requiring electromagnetic heating.

High-Temperature Devices: A specific property of silicon carbide for the applications in energy production is its ability to keep structural integrity intact at the temperature even high enough to create structural failures. It finds application in applications within the sensors and actuators space where the conventional material cannot work in high risk conditions.

Aerospace and Defense: SiC substrates are an ideal choice for the aerospace industry due to their high level of toughness which allows these parts to be used in the constituency of satellites and spacecraft exposed to harsh environments. They are perfect radiation-resistant electronics used by military in regions exposed to higher levels of radiation.

Automotive: SiC substrates are being used more frequently in power modules for electric automobiles as the industry moves toward more electric vehicles. They improve the overall performance of the vehicle by aiding in the management of the high power and temperature levels common to contemporary electric vehicle power systems.

Manufacturing Process of Silicon Carbide Substrate

SiC substrates are manufactured with great care, going through numerous crucial procedures to provide the best possible quality and performance:

Crystal Growth: Using physical vapor transport (PVT), high-purity SiC crystals are first created. By placing a silicon carbide seed crystal in a high-temperature gas environment, carbon and silicon atoms deposit onto the seed to grow the crystal’s size.

Wafering: After the crystal has grown to a suitable size, it is carefully cut with a diamond wire saw into thin wafers. To guarantee uniformity and the absence of structural flaws in the wafers, this phase needs to be carefully regulated.


Polishing: The previously cut wafers, however, go through a rigorous polishing procedure after that. Here, many mechanical and chemical polishing techniques can be used to achieve the reflective polish required for the subsequent production steps, such as the transistor creation process.

Dicing: After obtaining the specular wafers, the parts are divided into separate substrates by cutting them into little pieces. Cutting demands a keen sense of precision to avoid chipping the edges or going too deep, which could impair the functionality of the finished product.

Inspection and Packaging: The final step involves a flawless assessment of each substrate that has flaws including scratches, cracks, and contaminants. After that, they proceed to the quality control stage, where they are meticulously sorted and packaged for delivery to customers.
