Silicon carbide (SiC) wafers are also growing in popularity with the increase of applications that require more power dense electronics. The difference in SiC wafers is that they can handle higher power levels, operate at a much high frequency and endure with the high temperature. This unusual set of properties has attracted both manufacturers and end-users due to a market shift towards energy saving as well as high-performance electronic devices.
The semiconductor landscape is evolving rapidly, and SiC wafer technology has advanced the industry in terms of small devices that are more nimble, faster and consume less power. This level of performance is what has enabled the development and use in high voltage/high temperature power modules, inverters or diodes that are frankly unimaginable just a decade ago.
The changes in wafer chemistry of SiC wafers are characterized by its enhanced electrical and mechanical properties compared to traditional silicon-based semiconductors. SiC makes it possible to operate electronic devices at higher frequencies, voltages capable of managing extreme power levels and switching speeds. SiC wafers are chosen over other options for their outstanding qualities which deliver high-performance in electronic devices, also find application across a range of uses including EVs (electric vehicles), solar inverters and industrial automation.
EVs have rose in popularity massively, largely thanks to SiC technology contributing significantly towards their further development. SiC is capable of providing the same level of performance as competing components, which include MOSFETs, diodes and power modules but SiC offers a range of advantages over existing silicon solutions. The high switching frequencies of SiC devices reduce loss and increase efficiency, resulting in longer electric vehicle travel ranges on a single charge.

SiC wafers are manufactured using very high temperature and extremely high pressure to produce the best-quality wafers. Silicon carbide wafer production mainly uses the methods of chemical vapor deposition (CVD) and sublimation method. This can be done two ways: a process such as chemical vapor deposition (CVD), where SiC crystals grow on a SiC substrate in a vacuum chamber, or by the sublimation method of heating silicon carbide powder to form wafer-sized fragments.
Due to the complexity of SiC wafer manufacturing technology, it requires special equipment that affects directly their high quality. These parameters including crystal defects, doping concentration, wafer thickness etc which are decided during the manufacturing process have an effect on electrical and mechanical properties of wafers. Leading industrial players have constructed ground-breaking SiC manufacturing processes with advanced technologies to make premium quality manufactured SiC wafers that deliver improved device and strength attributes.
