Silicon Carbide Wafer 4H 4 inch Intelligence

About

Silicon Carbide Wafer 4H 4 inch is a high-performance semiconductor substrate made from silicon carbide crystal in the 4H polytype configuration. These wafers are produced through physical vapor transport (PVT) or modified Leitenberg methods, where silicon and carbon are heated to extreme temperatures to form single-crystal boules that are then sliced into precise 4-inch diameter wafers. The 4H polytype offers superior electrical properties including wide bandgap (3.26 eV), high breakdown voltage, and excellent thermal conductivity. Primary applications include power electronics, RF devices, LED manufacturing, and high-temperature sensors. Makers and engineers purchase these wafers for prototyping power MOSFETs, Schottky diodes, and RF amplifiers. Key properties include chemical inertness, radiation hardness, and operation at temperatures exceeding 600°C. The processed wafers undergo multiple polishing and cleaning steps to achieve the surface quality required for device fabrication.
