OTF-1100X-II-XX Two-Zone Tube Furnace with Optional Quartz Tube and Vacuum Flanges
The OTF-1100X-II-XX tube furnace is engineered for advanced laboratory thermal processing tasks such as chemical vapor deposition (CVD) and diffusion annealing, particularly suited for film growth of two-dimensional transition metal dichalcogenides (TMDs). It accommodates wafer sizes up to 12″ with an optional quartz tube diameter of 11″ or 15″ and integrates vacuum flanges for controlled atmosphere processing.
This model features two independently controlled heating zones, each 450 mm in length, providing a total heating zone length of 900 mm. The furnace employs a microprocessor-based PID control system with three K-type thermocouples, delivering precise temperature regulation within ±1°C and minimizing overshoot. The electrical lid actuator facilitates convenient and safe sample loading and unloading.

대표적인 적용 분야
This tube furnace is widely used for chemical vapor deposition (CVD) processes, annealing, and diffusion treatments of semiconductor wafers up to 12″ diameter. It is particularly suitable for research and development involving two-dimensional materials such as transition metal dichalcogenides (TMDs) and thin film growth requiring precise temperature control and vacuum environment.
구성 및 작동 안내
The furnace includes needle valves, vacuum gauges, and stainless steel vacuum flanges with silicon O-rings for vacuum sealing. An electrical actuator facilitates easy lid opening. Optional accessories include PC control software, Eurotherm controllers for enhanced temperature accuracy, calibration kits, quartz boats, and turbopumps for high vacuum applications down to 10^-5 torr.
Users should handle quartz tubes with care due to their fragility. The furnace is designed for vacuum or low-pressure operation below 0.2 bar and safe gas flow rates under 200 SCCM to prevent thermal shock. A two-stage pressure regulator is recommended to limit gas cylinder pressure below 3 PSI for safe operation.
