HTR & HTR-RF Series Horizontal Furnaces
Horizontal Thermal Reactors (HTR) & Reduced Footprint Horizontal Furnaces
HTR and HTR-RF horizontal furnaces are the workhorses of thermal processing, providing high-volume capabilities for semiconductor, solar, and other large-batch processes. Offering a large load size capability, Expertech’s new and remanufactured horizontal diffusion furnaces are compatible with cleanrooms down to Class 1 for world-class, low-contamination production solutions for 50mm to 450mm wafer sizes. With the ability to stack 3 or 4 horizontal furnaces, you can achieve exceptional, high production throughputs.
