What it is

General reference — not yet source-verified

The SVG Thermco 5000 Diffusion Furnace is a thermal diffusion furnace used in semiconductor manufacturing.

How it works

The Thermco 5000 series uses independently controlled heating zones, controlled gas delivery, and furnace control hardware for recipe execution and temperature management.[3]

Where it fits in the process flow

General reference — not yet source-verified

Diffusion furnaces sit in the thermal-processing part of the fab flow, after wafer formation steps and before later integration steps that depend on heat-treated films, junctions, or surface modification.

Applications

The Thermco 5000 series is used for processes including silicon nitride, polysilicon, TEOS LTO, BPSG, high-temperature oxide, high vacuum hydrogen anneal, dry oxide, wet oxide, POCl3 or BBr3 steps, forming gas anneal, high-temperature drive-in, alloy or temperature anneal, and hydrogen anneal.[3]

Frequently asked questions

How does a diffusion furnace achieve uniform processing across a batch of wafers?General reference — not yet source-verified

Uniformity is achieved through careful design of the heating zones, precise temperature control, consistent gas flow dynamics, and the use of baffles or other hardware. The tube geometry and boat design also contribute to even exposure of all wafers to the process ambient.

What types of gases are commonly used in diffusion furnaces?General reference — not yet source-verified

Typical gases include oxygen for oxidation, nitrogen as an inert purge or carrier, and dopant sources such as diborane, phosphine, or liquid dopant precursors. The specific gas mix depends on the desired process—for example, dry oxidation uses pure oxygen, while wet oxidation adds hydrogen.

How is the temperature profile controlled in a diffusion furnace?General reference — not yet source-verified

Multiple independently controlled heating zones along the tube allow the operator to set a temperature profile that is flat or tapered. Thermocouples inside the tube provide feedback to the controllers, enabling the system to maintain the set profile within tight tolerances during the process cycle.

What are common maintenance considerations for diffusion furnaces?General reference — not yet source-verified

Regular maintenance includes cleaning the quartz tube to remove deposits, replacing heater elements as they age, calibrating temperature sensors, and verifying gas delivery system integrity. The boat and hardware must also be inspected for contamination or damage to maintain process quality.
