Quartz Crucibles:
Setting the Standard for Flawless Silicon and Tomorrow’s Innovation
Quartz Crucibles
For Manufacturing
Single Crystal Silicon
Our quartz crucible sets the standard for semiconductor manufacturing. With exceptional purity, durability, and resistance to air pockets, it ensures flawless production of single-crystal silicon, even under the most challenging conditions. Built to last, it’s the key to driving innovation in tomorrow’s technology.
In manufacturing 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 a type of glass made almost entirely silica in an amorphous form, so contamination concerns are minimized and thermally stable .
