Custom annealing furnaces are precision thermal processing systems designed for controlled heat treatment, stress relief, defect healing, phase transformation, and atmosphere-controlled annealing of materials. They are widely used in semiconductor processing, crystal growth post-treatment, thin-film processing, ceramic materials, and advanced materials research.

Annealing is a critical step in optimizing crystal quality, electrical properties, optical performance, and mechanical stability. By precisely controlling temperature profiles, ramp rates, dwell times, and cooling conditions, a custom annealing furnace enables reproducible and uniform thermal treatment tailored to specific material systems.

Our annealing furnaces are fully customizable to meet diverse application requirements. Configurations include horizontal or vertical chambers, single-zone or multi-zone heating, and support for air, vacuum, inert gas, reducing, or oxidizing atmospheres. The system can be designed to accommodate wafers, bulk crystals, tubes, powders, or sealed ampoules, depending on the process needs.

High-quality insulation materials and advanced heating elements ensure excellent temperature uniformity and long-term stability, even at elevated temperatures. Integrated control systems provide programmable temperature recipes, real-time monitoring, and safety interlocks, supporting both research-scale experiments and pilot-scale production.
