What it is
How it works
General reference — not yet source-verifiedA diffusion furnace heats wafers in a controlled tube or chamber environment so dopants and thermal processes can act on the wafer surface and near-surface regions.
Thermal diffusion equipment is used to expose wafers to elevated temperatures with controlled gas delivery and time so process steps such as diffusion and related heat treatment can occur.
Where it fits in the process flow
General reference — not yet source-verifiedDiffusion furnaces belong in the wafer thermal-processing portion of the fab flow.
A diffusion furnace typically follows earlier wafer formation steps and supports thermal steps before later device completion steps.
Applications
General reference — not yet source-verifiedThermal diffusion furnaces are used for semiconductor wafer doping and other high-temperature process steps.
A furnace of this class is used for batch thermal processing of silicon wafers in mature semiconductor manufacturing flows.
