Crystal pulling

 
 

Wanted: reliable motion processes

Before the finished wafer leaves the production line, the silicon single crystal must undergo numerous process operations... These start with the crystal pulling process.

In crystal pulling machines, the requirement is for vibration-free, uniform feed movements. What can INA do about this?

A tailor-made solution for these requirements is, for example, our maintenance-free, four-row linear ball bearing and guideway assembly KUVE. Due to their low, uniform displacement resistance, they have uniform, precise running and thus allow the extremely slow but constant feed that is necessary in pulling of the silicon rods.
