About SIEGERT WAFER
SIEGERT WAFER GmbH from Aachen supplies universities, research laboratories and industry with wafers and substrates. The portfolio includes silicon wafers, substrates made of fused silica, Borofloat and other glasses, sapphire, SOI and silicon carbide as well as mask blanks, complemented by specialty materials such as germanium, III/V compound semiconductors (GaAs, InP and others), lithium niobate and single-crystal quartz. In addition to trading, the company operates its own grinding and polishing production for customer-owned or supplied wafers, including backgrinding, CMP polishing, reclaim and special grinding services such as pocket wafers. Further services include dicing, laser processing, coatings (PVD, CVD, thermal oxide, nitride, ITO) as well as metrology with SEM, AFM and ellipsometry. Thanks to a large warehouse, the company can deliver at short notice and also separate individual wafers from stock. SIEGERT WAFER coordinates external process steps as one-stop support through a network of specialized partners.
