Ultra-high-quality large ingot growth system

New technique(NOC、NOn-contact Crucible)

to grow High-Quality and Large Si crystal

 

Development system

Description

This new system incorporates the benefits of cast growth method, the Czochralski(CZ) method, Kyropoulos methodto have a function for the growth of the high-quality silicon crystal. The low-temperature region is formed in the silicon melt upper, growing ingot by pulling up the silicon crystal continuously using a seed crystal.
