The Tokyo Electron Unity II E 85 TPATC Dry is a dry etcher. The Tokyo Electron Unity II E 85 TPATC Dry is for 8-inch wafers.[1][2]
What it is
How it works
General reference — not yet source-verifiedDry etchers operate by creating a reactive gas environment in a process chamber so exposed areas of a wafer surface are chemically and physically removed. Dry etchers commonly work with a patterned masking layer that protects selected regions while open regions are etched.
Where it fits in the process flow
General reference — not yet source-verifiedDry etch equipment is used after a pattern has been defined on the wafer by a masking and lithography sequence. Dry etch equipment transfers that pattern into underlying films before later cleaning, stripping, inspection, or additional film formation steps.
Applications
General reference — not yet source-verifiedDry etchers are used for pattern transfer in semiconductor fabrication. Dry etchers can be applied to the shaping of conductive, dielectric, or semiconductor layers wherever plasma based removal is preferred over liquid phase etching.
