Alpha 303 i Vertical
What it is
How it works
General reference — not yet source-verifiedA vertical furnace is a batch thermal process tool. Wafers are loaded in a vertical stack and exposed to controlled heat in a process tube or chamber so that thermal reactions can occur uniformly across the batch.
In this class of tool, thermal processing may support oxide growth, deposition-related reactions, drive-in steps, annealing, curing, or similar heat-driven transformations, depending on the process recipe and installed configuration.
Where it fits in the process flow
General reference — not yet source-verifiedThis type of equipment sits in the wafer thermal processing portion of a fab flow, after wafer preparation and before later integration or finishing steps that depend on the thermal cycle being completed.
It is used when a process requires a controlled furnace step rather than a single-wafer rapid thermal operation, especially for batch treatment of multiple wafers under the same temperature program.
Applications
General reference — not yet source-verifiedAs a vertical furnace, it belongs to the class of equipment used for thermal steps in semiconductor fabrication, where heat is applied to a batch of wafers to form or modify thin films and material properties.
