The Tokyo Electron TEL ALPHA 8S is a vertical batch thermal processing system developed for semiconductor wafer oxidation, annealing and other high-temperature furnace processes. The available equipment listing identifies the platform for both 150 mm and 200 mm wafers.
ALPHA 8S systems were supplied in different process configurations. Depending on the installed furnace tube, gas system, quartzware and control software, an individual machine may be configured for wet oxidation, dry oxidation, annealing or selected LPCVD processes.

The TEL ALPHA 8S may be used for wet or dry thermal oxidation, dopant activation, thermal annealing and other batch furnace processes. Appropriately configured systems may also support silicon, silicon nitride or silicon oxide LPCVD processes.
The exact application should be confirmed from the process designation, furnace tube material, gas cabinet, MFC configuration, exhaust treatment, quartz boat and available process records.
The ALPHA 8S platform was supplied in multiple process variants, so the model name alone does not identify the installed process. Customers should confirm whether the available machine is configured for oxidation, annealing, diffusion or deposition.
Before quotation, the furnace tube, heater condition, quartzware, wafer boat, loading mechanism, gas panel, MFCs, temperature controllers, exhaust system, software and current power-on status should be inspected.
Contact our team to check the current availability of the used TEL ALPHA 8S. Please provide your wafer size, target thermal process, required gases, preferred batch configuration, destination country and installation schedule.
Contact us for equipment photos, process configuration, included quartzware, inspection status and quotation.
The available listing identifies the system for 150 mm and 200 mm wafers. The installed wafer boat and loading hardware must match the required wafer size.
No. Individual systems may be configured for oxidation, annealing, diffusion or selected deposition processes. The installed tube and gas system must be confirmed.
The platform has been used for wet and dry oxidation, but the required gas delivery, steam-generation equipment and process hardware must be present on the available machine.
Important checks include the heater, furnace tube, quartzware, loading mechanism, gas panel, MFCs, temperature control, exhaust system and operating software.
