- Discovered in 1891, Silicon carbide (SiC) is known for its extreme hardness and High-temperature resistance, and is used majorly since then as an abrasive, in cutting tools, bearings and in high temperature applications like crucibles for melting metals etc. Recently, demand of single crystal SiC wafers is gaining momentum in electronic chip manufacturing in semiconductor industries. Single crystal SiC is an electrical insulator and is optically transparent in pure form. Dopant like Nitrogen or Aluminum are added to tailor its electronic properties making it semiconducting. Addition of dopant also changes the color from transparent to green or blue transparent depending on the level of dopant impurities added. Also electrical conductivity can be controlled by varying doping concentration. SiC wafers have certain properties far superior than its counterpart Silicon wafer, making it strong contender for replacing Silicon wafer from semiconductor industry. Recently, Tesla has been using SiC based semiconducting chips in its electric vehicles. So in this article we will discuss what are the properties of SiC wafer which makes them better option for electronic chip manufacturing.
