How the CZ Growth Process Works
Step 1: Load Polysilicon
High-purity polysilicon is loaded into a quartz crucible.
Step 2: Melt Silicon
The furnace heats the polysilicon above the silicon melting point under controlled conditions.
Step 3: Insert Seed Crystal
A seed crystal is dipped into the molten silicon to start crystal growth.
Step 4: Pull and Rotate
The seed crystal is slowly pulled upward while rotating. The crucible also rotates to support uniform growth.
Step 5: Form Silicon Ingot
A cylindrical monocrystalline silicon ingot grows with controlled diameter and crystal orientation.
