GS-Single crystal silicon Czochralski Crystal Growth System

Product Description

This Czochralski Crystal Growth System is a CZ crystal growth system up to 2100°C and 2″ crystals. The high-precision upper weighing device facilitates better control of crystal growth process including seed dipping, shoulder expansion, and steady growth.  The upper pulling mechanism ensures a minimum pulling speed of 0.03mm/h and a rotation speed of 1 rpm. The stainless steel water-cooled chamber, paired with a vacuum pump, can achieve a maximum vacuum of 3.75e-5 torr. It is designed to grow various oxides, metals, and other materials, such as sapphire, GGG, YAG, LaAlO3, Si, Ge, Cu, and more. Customization for special technical requirements is available.
