Silicon Pulling Quartz Crucibles

Silicon pulling quartz crucibles are typically positioned in the central zone of a single crystal furnace and are held by graphite crucibles, together with other thermal field components including insulation barrels, guide cylinders and heaters for silicon ingot pulling. Semiconductor and PV industries set stringent requirements on silicon wafer quality, requiring tight control over purity, defect density, dislocations and impurity levels (e.g., oxygen, carbon and metal ion content). Silicon pulling quartz crucibles, as the indispensable containers that hold molten polysilicon, will come in direct contact with silicon feedstock, exerting a significant impact on the wafer quality, production yield and stable consistency across batches.

Advantages of Semicorex silicon pulling quartz crucibles

1. High-level cleanliness control

Semicorex uses PV and semiconductor-grade raw materials to produce our quartz crucibles and rigorously control each production step to avoid metallic contamination. Our silicon pulling quartz crucibles can fully satisfy the strict industry cleanliness requirements and significantly minimize undesired impurity contamination from affecting the crystal quality of silicon ingots.

2. Excellent thermal management capability

Semicorex silicon pulling quartz crucibles allow long-term stable service at 1100 °C and short-term operations at 1450 °C. Our silicon pulling quartz crucibles can maintain reliable strength under extreme high-temperature working conditions without deformation or collapsing during continuous single-crystal pulling.

3. Flexible size options

Semicorex offers custom production of our silicon-pulling quartz crucibles in terms of crucible dimensions, inner coating, bubble level, and material purity. Their diameter ranges from 14 to 36 inches, which makes our silicon-pulling quartz crucibles suitable for both small-scale laboratory research and large-scale industrial production.
