Technology & Products
Key Products
TekSiC designs and manufactures precision high-temperature induction heating furnaces for silicon carbide crystal growth and advanced materials processing. Products: Xforge PVT (physical vapor transport furnace for SiC crystal growth), Xforge HT (high-temperature heat treatment system), and SiC Consumables (seeds, powder, and graphite). TekSiC is also developing Europe's first domestic semi-insulating SiC (SI-SiC) wafer supply for space, defence and RF applications.
Technological Advantage
Compact high-temperature induction heating furnaces with exceptional temperature stability (up to 2500°C); modular systems serving both R&D process development and production-scale integration; custom-tailored solutions with process development services rather than standardized products; proven reliability with systems running in production since 2023.
Differentiation
Value Proposition
Delivers precision-engineered, customer-centric furnace solutions developed with 60+ years of combined SiC crystal growth expertise through direct collaboration with leading semiconductor companies, providing unmatched versatility and reliability for both research and production-scale applications.
