What it is
How it works
General reference — not yet source-verifiedWet etchers process wafers by immersing or spraying them with liquid chemical etchants that selectively remove material from exposed surfaces.
The EO 222 SR uses a wet chemical process to etch layers, relying on chemical reactions rather than plasma or dry methods.
Where it fits in the process flow
General reference — not yet source-verifiedWet etching is a batch or single-wafer process used to remove material layers during semiconductor fabrication, often before or after photolithography and deposition steps.
The EO 222 SR belongs to the etch category of fab equipment, positioned alongside other etch tools that pattern or clean wafers as part of the overall process flow.
Applications
General reference — not yet source-verifiedThe primary application of the EO 222 SR is wet etching of semiconductor wafers.
Typical wet etch applications include removing oxide, nitride, or metal layers, and cleaning wafer surfaces before subsequent processing steps.
