TECHNOLOGY
European Technology covered by more than 30 Patents
EEMCO‘s vertical integration ensures superior SiC crystal quality, starting with high-grade SiC powder sourced and recycled by our subsidiary, SICREATE. Leveraging EBNER‘s 75+ years of furnace expertise, we design and manufacture our proprietary SiC growth furnaces, incorporating advanced technologies like digital twins and Industry 5.0 for real-time process optimization and secure data sharing with customers.
Our SiC manufacturing begins with high-quality powder which is sublimated within EBNER built furnaces, depositing onto a seed crystal to form a boule. The boule is then ground, wafered, and polished, with quality checks at each stage.
This vertical integration, from powder sourcing to wafer production, combined with European supply and R&D partnerships, enables EEMCO to efficiently drive innovation in defect reduction and crystal size expansion beyond 200 mm.
Our Commitment
Our vision is to produce with 100 % green energy at EEMCO, offering higher quality and competitive pricing. We commit to emphasize renewable energy use and raw material recycling.
MANUFACTURING PROCESS
From Raw Material to Ingot
The SiC manufacturing process begins with high-quality SiC powder, sourced and recycled by EEMCO’s subsidiary, SiCreate. This powder is placed within a crucible inside a specialized furnace, developed and provided by EBNER.
Within the furnace, a seed crystal is introduced, and the SiC powder undergoes a process called Physical Vapor Transport (PVT). Under high temperatures, the SiC powder sublimates into a gas and redeposits onto the seed crystal, gradually forming a larger SiC crystal known as a boule.
Once the boule is grown, it is removed from the furnace. Its outer diameter is then ground and polished, and a „witness wafer“ is extracted for quality analysis. The boule is then sliced into thin discs called ingots using a multi-wire saw. These ingots are further processed and polished into SiC wafers, ready for use in manufacturing power electronics.
