Shaping the Future of Semiconductors

Purity

Ultra-pure quartz with high stability and low inclusions – the benchmark for demanding semiconductor applications.

HSQ MF ingots are produced by electric fusion, achieving exceptional purity and visual clarity. With very low inclusions and almost zero bubbles, superior thermal shock resistance, and high optical transmission, HSQ MF is the material of choice for leading-edge high-end semiconductor processes. This combination of purity, stability, and innovation positions Heraeus Covantics as a benchmark in fused silica materials in demanding applications.
