How EKOHEAT Supports Semiconductor Crystal Growing

Product catalog summary

Introduction
The document discusses the role of precision induction heating in the production of high-purity crystal substrates, particularly for semiconductor applications. It highlights the importance of non-contact heating methods in processes such as Czochralski, Micro-pulling down, Float zone, and Bridgman-Stockbarger.

Induction Heating in Crystal Growth
Induction heating is crucial for controlling the temperature of the molten mass during crystal growth. It offers a clean, non-contact method of heating, which is beneficial for maintaining the purity and quality of semiconductor crystals used in LEDs, integrated circuits, and solar panels.

EKOHEAT System Features

Frequencies ranging from 3kHz to 150kHz.
Power output from 15kW to 500kW.
Output regulation for 360 - 520 Vac.
Precisely controlled power with a 100% duty-cycle.
Automatic power reset and lower coil voltages.
Efficient power conversion with a power factor greater than 0.9.
Options for internal or external heat stations.

Advantages of Induction Heating
Induction heating provides strict control over critical temperatures, supports varying atmospheric conditions, and reduces demand charges due to its efficient power conversion.
