Tokyo Electron Alpha 8 S Z is a low-pressure chemical vapor deposition (LPCVD) system. Alpha 8 S Z is a model in the Tokyo Electron Alpha family.[1]
What it is
The Alpha 8 S Z is a low-pressure chemical vapor deposition (LPCVD) system. The Alpha 8 S Z is a product of Tokyo Electron.[2][1]
How it works
General reference — not yet source-verifiedIn LPCVD, gaseous precursors are introduced into a heated reactor. The chemical reaction of the precursors deposits a solid film on the wafer surface.
The low operating pressure reduces gas-phase reactions, promoting surface-reaction-limited growth for better uniformity. Thermal activation provides the energy needed for the deposition reaction.
Where it fits in the process flow
General reference — not yet source-verifiedLPCVD films serve as dielectric layers, passivation, or structural materials in integrated circuit manufacturing. The tool may be part of a batch processing sequence for multiple wafers.
