Silicon carbide wafers are round sheets made of SiC that look similar to silicon wafers. It is a very important semiconductor material with high hardness, heat resistance, radiation resistance, corrosion resistance, and high conductivity.
SiC wafers are one of the key materials for manufacturing high-performance electronic devices, and can perform excellent performance under high temperature, high electric field, high frequency, and high pressure environments.
VIMATERIAL can provide 2~6 inch silicon carbide wafers.
SiC wafers have many excellent physical, chemical, and electrical properties, making them widely used in electronics, optoelectronics, aerospace, and other fields. The main characteristics of silicon carbide wafers include:
1. Strong high temperature stability: SiC wafers have extremely high thermal conductivity and chemical inertness, can maintain stability in high temperature environments, and are not prone to thermal expansion and deformation.
2. High mechanical strength: SiC wafers have high stiffness and strength, and can withstand high stress and heavy loads.
3. Excellent electrical properties: The electrical properties of silicon carbide wafers are better than those of silicon materials, with higher electrical conductivity and electron mobility, and can be used to manufacture high-power semiconductor devices and high-frequency electronic devices.
4. Excellent optical properties: SiC wafers have good light transmittance and strong radiation resistance, and can be used to manufacture optoelectronic devices and solar devices.
SiC wafers have higher hardness and better corrosion resistance than silicon wafers, and can be used for applications in high temperature, high pressure and chemically harmful environments. In addition, silicon carbide wafers have better thermal conductivity and electrical properties, and can still maintain good stability in high temperature environments.
Since SiC wafers have the above-mentioned excellent performance characteristics, they are widely used in electronics, optoelectronics, aerospace and other fields. The main applications include:
1. Manufacture of high-power semiconductor devices: SiCwafers have characteristics such as high thermal stability and high electrical conductivity, and can be used to manufacture high-power semiconductor devices such as power MOSFET, Schottky diode, JFET, etc.
2. Manufacturing high-frequency electronic devices: SiC wafers have high electron mobility and can be used to manufacture high-frequency electronic devices, such as high-frequency transistors, high electron mobility transistors, etc.
3. Manufacturing optoelectronic devices: SiC wafers have good light transmittance and can be used to manufacture optoelectronic devices, such as LED chips, laser diodes, etc.
4. Manufacturing solar devices: Silicon carbide wafers have strong radiation resistance and can be used to manufacture solar devices.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
