What it is
General reference — not yet source-verifiedTokyo Electron Alpha 8 S ZCN Poly is a vertical thermal furnace used in semiconductor fabrication for batch thermal processing. The machine belongs to the category of thermal/diffusion equipment, which performs processes such as oxidation, diffusion, and chemical vapor deposition at high temperatures.
Where it fits in the process flow
General reference — not yet source-verifiedThermal furnaces of this type are used in the front-end-of-line (FEOL) portion of a semiconductor fab. Polysilicon layers deposited in such furnaces serve as gate electrodes in MOS transistors, as resistor elements, or as part of memory cell structures. Upstream process steps include gate oxide growth or cleaning; downstream steps involve lithographic patterning and etching of the polysilicon layer.
Applications
General reference — not yet source-verifiedThe primary application of the Alpha 8 S ZCN Poly is low-pressure chemical vapor deposition of polysilicon. The furnace is also used for thermal oxidation, to grow silicon dioxide, and for dopant diffusion, to introduce controlled amounts of impurities into silicon wafers. Other possible processes include nitride deposition and post-implant annealing.
