In the manufacture of silicon wafers for semiconductor applications, polysilicon starting materials are placed in a fused quartz crucible, heated to high temperatures and pulled from the melt as a single crystal. Fused quartz is the oxide of the silicon molten in it, minimizing contamination concerns, and one of the few materials that can combine the high purity and high temperature properties required.
Momentive Technologies offers a variety of compositions, from natural to synthetic silica materials, and customizable properties such as bubble content to optimize optical transmission and inner surface glass quality. A wide variety of customizable designs and coatings are available to optimize cost of ownership.
