PVA TePla is an association of diverse high-tech companies that operate worldwide. Backed by decades of experience and an eye for the innovations of tomorrow, we develop unrivaled systems for vacuum, high-temperature, and plasma processes as well as for quality inspections—always in close cooperation with our customers.
For more than 60 years, PVA Crystal Growing Systems supports our customers in the production of high-purity monocrystals (Si, SiC, Ge, GaAs, InP). More than 1000 of our customized systems were sold to the semiconductor, photovoltaics, electronics and R&D industries.
The Czochralski crystal growing system CGS1218 is specially designed for the high demands of the semiconductor industry. It has a modular design and can be configured with either a cable or a crystal shaft. The unique shaft configuration enables highest precision and therefore absolute linearity and reproducibility of the pulling speed.
The SiCma system was specially developed for the production of silicon carbide (SiC) crystals by means of physical vapor transport (PVT). In this process, the powdered starting material is heated and sublimated at high temperatures and finally deposited on a specially prepared substrate. This is done by inductive heating in the kilohertz range using an induction coil. The design of this coil is optimized for low energy consumption.
The FZ-14 Float-Zone crystal-growing system is designed for the industrial production of monocrystalline Silicon crystals with a diameter of up to 100 mm (4").
