Semiconductor devices, the foundation of the semiconductor industry, are manufactured by creating a fine electronic circuit on a silicon wafer made of single-crystal silicon.
Single-crystal silicon is made from high-purity polycrystalline silicon (polysilicon) and is grown by filling a quartz crucible with the silicon before heating and melting it in the extracting machine.
A high-purity quartz crucible is the optimal container to ensure the purity of molten silicon when manufacturing single-crystal silicon.
