First, wafer characteristics and selection
The surface area of the wafer directly determines the number of integrated circuits that can be manufactured from the wafer.
However, with the increase in surface area, the cost of manufacturing wafers also rise accordingly, but the increase in cost is not strictly proportional to the surface area.
Currently, the largest wafers on the market are up to three hundred millimeters in diameter, but there are variations in capacity and specifications between suppliers, so it is important to check that the supplier can meet your specific needs when shopping around.

Application areas of 4H-SiC semi-insulated wafers
4H-SiC semi-insulated wafers show a wide range of potential applications in many fields due to their excellent performance.
1. Power electronics: 4H-SiC wafers are ideal for the manufacture of power switching devices, such as MOSFETs (Metal Oxide Semiconductor Field Effect Transistors), IGBTs (Insulated Gate Bipolar Transistors) and Schottky diodes. These devices exhibit lower conduction and switching losses in high-voltage, high-temperature environments, greatly improving system efficiency and reliability.
2. Radio Frequency (RF) Devices: 4H-SiC semi-insulated wafers shine in high-frequency applications, and can be used to make high-power, high-frequency RF power amplifiers, chip resistors, filters, and other devices. The larger electron saturation drift rate and higher thermal conductivity of SiC give it excellent high-frequency performance and thermal stability.
3. Optoelectronic devices: In the field of optoelectronic devices, 4H-SiC semi-insulated wafers are also outstanding, and can be used to manufacture high-power laser diodes, ultraviolet detectors and optoelectronic integrated circuits.
