The best price in the market for 2 inch and 3 inch Research grade Silicon Carbide substrate wafers is offered by us. LED is an energy-saving cold light source, which consists of the combination of semiconductor electrons and holes, and is one of the most commonly used electronic components.

 

Features:

Silicon Carbide (SiC) Single Crystal
Silicon Carbide (SiC) single crystal is an innovative material with many remarkable properties. It has high thermal conductivity, which helps it to dissipate heat more efficiently than traditional materials. Besides, its high saturated electron mobility makes it the ideal choice for high frequency electronic devices, whereas its high voltage breakdown resistance makes it resistant to potential damages caused by electric charge. Most significantly, this crystal is also capable of withstanding high temperature and radiation, making it suitable for producing highly reliable and durable electronic devices.

Technical Parameters:

Silicon carbide (SiC) substrates or wafers can have either the 6H or 4H crystal structure, with lattice parameters of 6H (a=3.073 Å, c=15.117 Å) and 4H (a=3.076Å, c=10.053 Å) respectively. The 6H structures has a stacking sequence of ABCACB, and 4H structures have ABCB. They are available in production grade, research grade, or dummy grade.

SiC substrates can be N-type or semi-insulating, with the band-gap at 3.23 eV. The Mohs scale hardness for SiC substrates is 9.2, and the thermal conductivity is 3.2-4.9 W/ cm.K. The dielectric constants are e(11)=e(22)=9.66 and e(33)=10.33. Resistivity ranges from 4H-SiC-N (0.015-0.028 Ω·cm), 6H-SiC-N (0.02-0.1 Ω·cm), to 4H/6H-SiC-SI (>1E7 Ω·cm). Packaging is done in a Class 100 clean bag, in a Class 1000 clean room.

 

Applications:

Silicon Carbide Wafer, commonly known as SiC wafer, is a kind of substrate that is suitable for automotive electronics, optoelectronic devices, and industrial applications. It includes 4H-N Type SiC substrate and Semi-Insulating SiC substrate. These Silicon Carbide Wafer varieties are capable of withstanding high temperatures and creating highly efficient electronic circuits.

The 4H-N type SiC substrate is the most widely used variety. It provides higher breakdown voltage, better temperature stability, and lower leakage current than most wafer materials. Semi-Insulating SiC substrate, on the other hand, has a lower rate of electrical leakage. It also has a constant breakdown voltage over time and temperature and low temperature coefficient of resistance.

SiC wafer is an ideal choice for energy and efficiency-conscious designs and is gaining more and more traction in the automotive, optoelectronic, and industrial applications. It has intrinsic thermal and electrical properties that are beneficial for microelectronic device performance and is widely used in the development of high-performance, low-power ECUs and optoelectronic devices.

Packing and Shipping:

Packaging and Shipping Silicon Carbide Wafers:

Silicon Carbide Wafers are shipped in protective containers to ensure that they remain safe during transit. The packaging must include cushioning materials to reduce shock and vibration. They are typically shipped as a single unit and must be handled with care. Special packaging is available for long-term storage or high-temperature applications.

The shipping method for Silicon Carbide Wafers can vary depending on the customer’s needs, but typically they are sent via a courier service. All packages must be clearly labeled with the contents, recipient, and sender. Additionally, the courier should be provided with the necessary paperwork for customs clearance.
