OEM Replacement Heater Cores for Bruce Diffusion Furnaces
If you operate a Bruce horizontal diffusion furnace, you need heater cores from the people who designed it. As the original manufacturer of the Bruce Diffusion Furnace (BDF), BTU International supplies factory-engineered replacement heater cores built to the original design specifications — ensuring your furnace continues to deliver the temperature uniformity and process consistency your applications demand.
Built by the Original Manufacturer
The BDF heater core is the thermal heart of your horizontal diffusion furnace. Its geometry, winding pattern, and material set were engineered specifically for the BDF platform. A heater core that merely fits isn’t the same as one that performs — and in high-temperature semiconductor processing, that difference matters.
- Original design specifications — manufactured to the same engineering standards as the original equipment
- Purpose-built for horizontal diffusion furnaces — geometry and thermal profile matched to the BDF platform
- High-temperature material set — selected specifically for diffusion, oxidation, and anneal environments
- Optimized thermal uniformity — reducing drift, variability, and requalification risk after replacement
- Drop-in compatibility — designed to fit existing BDF furnace hardware without modification
- Over 30 years of BDF design expertise — backed by decades of Bruce horizontal furnace engineering knowledge

Stock a Spare Before You Need One
Heater cores are consumable components with a finite service life. In a horizontal diffusion furnace, an unexpected heater failure means furnace downtime — and in semiconductor manufacturing, downtime is expensive. Lead times for replacement cores are not trivial.
Facilities that operate Bruce diffusion furnaces are well-advised to maintain at least one spare OEM heater core on-site. Stocking a spare allows you to:
- Swap immediately at end of life rather than waiting on manufacturing lead time
- Plan heater replacement during scheduled maintenance windows instead of reacting to failures
- Avoid expediting costs and emergency procurement
- Protect wafer throughput and production schedules
- Minimize unplanned process requalification events
Applications
OEM BDF heater cores support horizontal diffusion furnace processes including:
- Thermal oxidation
- Annealing
- Drive-in diffusion
- Doping processes
- LPCVD and related high-temperature treatments
