Process
Several steps are involved in the fabrication of SiC wafers, including dicing and polishing. The various dicing steps require varying feed rates and spindle speeds. This process yields a wafer with a relatively smooth surface and low roughness. The process also increases yield.

The final major step in the SiC wafer production process is chemical mechanical polishing, which aims to prepare the substrate surface for epitaxial growth while causing minimal shape change. To remove only a few microns from the surface of the wafer, this process typically employs a chemically reactive slurry and a polyurethane-based polishing pad. A template or vacuum chuck with a backing film holds the SiC wafer in place.

This process, in addition to annealing, checks for crystal defects. These flaws can have a negative impact on the semiconductor’s performance. The silicon carbide wafers that result are then sliced into individual chips. This manufacturing process ensures higher quality and efficiency, as well as the ability to meet specific customer requirements.

An important parameter for SiC dicing is the dicing blade. It is critical to select one with a resin-bonding blade. This blade is designed specifically for SiC dicing. Furthermore, it is critical to select a spindle speed that reduces blade vibration.

SiC wafers are among the best semiconductor materials on the market today. Its superior electrical and thermal properties make it ideal for a wide range of electronic devices. It has a high resistance to thermal and electrical radiation and can be used in a variety of power and voltage applications. Silicon carbide wafers are widely used in power conversion and have many other applications.

To make high-quality SiC wafers, the silicon substrate must first be prepared. The silicon wafer is oxidized during this process, and the number of dislocations and scratches on the surface is reduced. This process will make your SiC wafer thinner than standard semiconductors. However, specialized tools will be required for the job.

Another distinguishing feature of SiC is its low field mobility. It has superior electrical properties to SiO2 and is frequently used in power devices. Device simulation technologies are required for the design and manufacture of SiC power devices.
