Description of 4H-N SiC
Silicon carbide (SiC) wafers are a semiconductor material with unique physical and chemical properties.
They have attracted much attention for their high breakdown electric field strength, high electron mobility and excellent thermal conductivity.
SiC is widely used in electric vehicles, renewable energy, RF devices and power electronic devices, and plays an important role in the production of power MOSFETs, Schottky diodes and other fields.
Of course, in the field of electric vehicles, SiC devices can significantly improve power conversion efficiency and driving range, and SiC inverters in renewable energy systems help improve energy conversion efficiency and system reliability.
In addition, SiC wafers can increase the switching speed and operating frequency of devices in RF applications, promoting the development of high-frequency electronic components.
Although the current manufacturing cost is high, mainly due to the complexity of material preparation and processing, with the continuous advancement of technology and improvement of processes, the cost is gradually decreasing.
SiC wafers not only promote the miniaturization and efficiency of electronic devices but also bring new development opportunities for future energy conversion and electric vehicle technology. Its market prospects and technical potential are very broad.
With the maturity of manufacturing technology and the expansion of application scope, silicon carbide wafers will be widely used in more fields and become an important driving force for the development of next-generation electronic devices.
ZMSH has been deeply involved in the SiC field for many years, providing a variety of SiC products to global customers, focusing on customer service and product quality, and striving to become a top-tier high-tech enterprise in the field of optoelectronic materials.
