What it is
How it works
General reference — not yet source-verifiedVertical thermal furnaces process a boat of wafers as a batch, with the process tube sealed at the load end and the wafer boat raised into the heated zone.
The furnace controls atmosphere composition, temperature ramp rates, soak time, and cool-down profile to deliver a repeatable thermal cycle across the batch.
Where it fits in the process flow
General reference — not yet source-verifiedAnnealing steps in a fab typically follow ion implantation, where the furnace activates implanted dopants and restores lattice damage, or follow deposition steps where the thermal cycle densifies and stabilizes thin films.
After annealing, wafers continue to downstream operations such as photolithography, etch, further deposition, or metallization depending on the point in the overall integration flow.
Applications
General reference — not yet source-verifiedTypical furnace anneal applications include dopant activation after implantation, oxide growth, nitride deposition, and thermal annealing of deposited layers.
