Dual Zone Tube Furnace 1100C with 11 Inch Quartz Tube and Vacuum Flanges for 8 Inch Wafer Processing

Product Overview

This high-performance dual zone tube furnace is a sophisticated thermal processing system designed for advanced material research and industrial R&D. Featuring an exceptionally large 11-inch O.D. fused quartz tube, the equipment provides a spacious heating environment suitable for large-scale samples and semiconductor wafers up to 8 inches in diameter. The dual-zone configuration allows for the creation of precise thermal gradients or a wider constant temperature zone, offering researchers unparalleled flexibility in managing complex heat treatment profiles. By integrating high-purity alumina fibrous insulation, this system ensures maximum energy efficiency and rapid thermal response times.

The equipment is specifically engineered for high-purity applications, including the sintering of new material samples and the annealing of semiconductor wafers under vacuum or controlled gas atmospheres. Target industries range from semiconductor manufacturing and metallurgy to nanotechnology and renewable energy research. The large-diameter processing chamber allows for higher throughput and the accommodation of specialized crucibles and boats, making it an ideal choice for laboratories transitioning from small-scale experimentation to pilot-scale development. Its robust vacuum capabilities and gas handling features facilitate precise control over the chemical environment during critical processing stages.

Reliability and consistency are the hallmarks of this unit's design. Built to withstand demanding industrial conditions, the system utilizes high-precision digital controllers and durable NiCrAl resistance wire heating elements to maintain stable performance over extended periods. The inclusion of water-cooled stainless steel flanges protects the integrity of vacuum seals, ensuring a leak-free environment even during high-temperature cycles. This commitment to engineering excellence ensures that every process, from basic calcination to advanced chemical vapor deposition, is performed with repeatable, high-accuracy results that professional researchers can depend on.

Key Features

• Precision Dual-Zone Temperature Control: The system features two independently controlled heating zones, each 300mm in length, managed by high-precision PID digital controllers. This allows for the establishment of stable thermal gradients or a combined 300mm constant temperature zone with ±1°C accuracy, essential for processes like TMD nanoribbon growth.
• Extra-Large 11-Inch Quartz Chamber: Equipped with a massive 279mm O.D. fused quartz tube, this furnace accommodates large-format samples, including standard 8-inch semiconductor wafers. The high-purity quartz material provides excellent thermal shock resistance and chemical inertness, ensuring a contaminant-free environment.
• Advanced Hinged Vacuum Flanges: The stainless steel vacuum flanges feature a hinged design for effortless sample loading and unloading. Integrated water-cooling channels in the double-layer flange structure effectively protect the O-ring seals, maintaining vacuum integrity during sustained operation at temperatures up to 1100°C.
• High-Efficiency Thermal Insulation: Utilizing high-purity alumina fibrous insulation, the equipment minimizes heat loss and reduces energy consumption. This lightweight, high-performance insulation also enables faster heating and cooling rates, optimizing the overall cycle time for laboratory throughput.
• Robust Heating Elements and Safety: Long-life NiCrAl resistance wire heating elements provide consistent heat distribution. For operator and equipment safety, a secondary temperature monitor is included to protect against over-temperature conditions and broken thermocouples, providing peace of mind during unattended operation.
• Integrated Gas and Vacuum Porting: The system includes a mechanical vacuum gauge, two stainless steel needle valves, and a KF25 vacuum port. This comprehensive fitting suite allows for precise atmosphere management, supporting vacuum levels from 10-2 torr with mechanical pumps up to 10-4 torr with turbomolecular systems.
• Programmable Heat Treatment Profiles: Both temperature controllers support 30 programmable segments, allowing users to automate complex ramp, soak, and cool-down sequences. This ensures high reproducibility across multiple batches, which is critical for standardized research and industrial quality control.
• Computer Interface and Data Logging: The equipment is compatible with specialized Labview-based control software, enabling researchers to edit temperature profiles, manage recipes, and record real-time data on a PC for thorough post-process analysis and documentation.
