The Alpha 85 Z is a thermal/diffusion furnace manufactured by Tokyo Electron. The Alpha 85 Z handles 8-inch wafers. The Alpha 85 Z is configured for POCL3 processing.[1]
What it is
General reference — not yet source-verifiedThe Tokyo Electron Alpha 85 Z is a diffusion furnace classified under the Thermal / Diffusion equipment category. Diffusion furnaces are used in semiconductor manufacturing for processes such as thermal oxidation, dopant diffusion, and annealing of silicon wafers.
Where it fits in the process flow
General reference — not yet source-verifiedThe furnace process is typically preceded by a cleaning step (e.g., RCA clean) and may be followed by a drive-in anneal or oxidation step to activate and diffuse the dopant further.
