Ingot pulling with rotary-servo

Challenge

As the seed crystal is slowly being pulled from the molten silicon, the right diameter can be obtained by controlling and adapting the pulling speed of the crystal. This process must be continued during the growing of the complete ingot.

Solution

Precision and exact positioning characterise the servo drives of Omron. Self-tuning guarantees fast and flawless installation. Omron’s servos operate with reduced vibration, guaranteeing smooth movements.

Benefits

Due to the controlled movement of the seed crystal, the product of the process is an ingot of constant diameter and high quality silicon.
