What it is

The Lindberg/Blue M HTF and STF series are three-zone tube furnaces that use digital temperature controllers and individual thermocouples for each zone. The STF55433 is a general-purpose tube furnace rated for 1500 °C.[3][2]

How it works

The Lindberg/Blue M HTF and STF series tube furnaces employ three-zone control systems for precise temperature management. Each zone is measured by an individual thermocouple and is controlled by a digital temperature controller. The furnaces require a customer‑supplied process tube for operation.[3]

Where it fits in the process flow

General reference — not yet source-verified

In semiconductor manufacturing, tube furnaces are used for thermal processes such as diffusion, oxidation, annealing, and chemical vapor deposition. The wafers are loaded into the process tube in a boat and subjected to controlled temperature ramps and gas flows. Tube furnaces are typically preceded by wafer cleaning and followed by metrology steps to verify film thickness or junction depth.
