Monocrystalline silicon growth furnace monocrystalline silicon ingot growth system equipment temperature up to 2100℃

Short Description:

Monocrystalline silicon growth furnace is a key equipment for the production of high purity monocrystalline silicon rods, which are widely used in semiconductor and photovoltaic industries. Monocrystalline silicon is the core material in the manufacture of integrated circuits, solar cells and other electronic devices. Monocrystalline silicon growth furnaces convert polysilicon raw materials into high quality monocrystalline silicon rods by using techniques such as Czochralski (CZ) Czochralski or floating zone method (FZ).

Core function: Heating polysilicon raw material to a molten state, guiding and controlling crystal growth through seed crystals to form monocrystalline silicon rods with specific crystal orientation and size.

The main components:
Heating system: Provides a high temperature environment, usually using graphite heaters or high frequency induction heating.

Crucible: Used to hold molten silicon, usually made of quartz or graphite.

Lifting system: control the rotation and lifting speed of the seed crystal to ensure uniform crystal growth.

Atmosphere control system: The melt is protected from contamination by inert gases such as argon.

Cooling system: Control crystal cooling rate to reduce thermal stress.

Main characteristics of monocrystalline silicon growth furnace

(1) High precision control
Temperature control: Precisely control the heating temperature (the melting point of silicon is about 1414°C) to ensure melt stability.
Lifting speed control: the lifting speed of the seed crystal is controlled by a precision motor (usually 0.5-2 mm/min), which affects the crystal diameter and quality.
Rotation speed control: Adjust the rotation speed of the seed and crucible to ensure uniform crystal growth.

(2) high-quality crystal growth
Low defect density: By optimizing the process parameters, the monocrystalline silicon rod with low defect and high purity can be grown.
Large crystals: monocrystalline silicon rods up to 12 inches (300 mm) in diameter can be grown to meet the needs of the semiconductor industry.
