Hana Materials, Inc. manufactures and sells silicon materials for semiconductor products. Its products include silicon ingot, electrode, ring, silicon carbide, fine ceramics and specialty gases.

Bellmann described the discarded sawdust silicon powder as “black gold” and said that around 35% of the silicon in ingot and wafer ... smelt silicon for silicon carbide production.

Through this process, the impurities are initially released into a solid solution and then undergo diffusion through the silicon ... from subsequently pulled ingots with varying impurity ...

The facility will integrate the entire process of manufacturing power devices starting from raw materials to silicon carbide crystal ingot growth, wafer slicing and polishing and the process of ...
