According to our (Global Info Research) latest study, the global Semi-Insulating Silicon Carbide Seed Crystal market size was valued at US$ 14.92 million in 2025 and is forecast to a readjusted size of US$ 54.89 million by 2032 with a CAGR of 20.4% during review period.
Semi-insulating silicon carbide (SiC) seed crystal refers to a high-resistivity SiC single-crystal seed engineered to provide a crystallographic template for bulk crystal growth while maintaining semi-insulating electrical behavior. The semi-insulating property is typically achieved by deep-level compensation—either via vanadium (V) doping or by growing ultra-high-purity, impurity-controlled SiC so that residual shallow donors/acceptors are compensated.
Upstream inputs include a qualified SiC single crystal (boule/ingot) from which the seed wafer is cut and finished, high-purity SiC source material (powder) for sublimation/PVT growth, and compensation dopant sources when applicable (e.g., vanadium-bearing species). In practice, transition-metal dopants such as vanadium are used to compensate residual nitrogen, and the seed is processed through slicing, lapping, polishing/CMP, and orientation control (on-axis/off-axis) to meet growth and device requirements.
Downstream, the SI-SiC seed crystal is loaded into PVT/seeded-sublimation (or related high-temperature growth) furnaces to grow semi-insulating SiC boules, which are then converted into semi-insulating substrates. These substrates are widely used as the platform for GaN-on-SiC RF power amplifiers and other RF/microwave devices, serving telecom as well as aerospace/defense applications.
In 2025, global production of semi-insulating silicon carbide seed crystal reached approximately 27 K Pcs, with an average global market price of around US$ 539/Pcs. Production capacity varies significantly among manufacturers, with gross profit margins ranging from approximately 5% to 30%.
