Etching is a controlled material-removal process used in semiconductor manufacturing to selectively remove dielectric, metal, or silicon layers from a wafer while protected areas remain untouched, effectively transferring the lithographic pattern into the underlying film. In fabrication documentation, etching appears in process flow specifications, etch tool recipes, post-etch inspection criteria, and defect reduction reports where it is described alongside lithography, deposition, and metrology steps.
In translation and localization, etching terminology appears in equipment manuals, process specifications, EHS documents, quality control procedures, and failure analysis reports. Translators encounter it when localizing fab engineering documents, operator training material, supplier quality agreements, and corrective action records where wet etch, dry etch, plasma etch, and etch selectivity must be distinguished accurately.
A common error is translating etch as 'corrosion' or 'engraving' in process documents, which obscures the controlled patterning purpose and could be mistaken for unintended material damage. Another mistake is using the same target term for wet etch and plasma etch without indicating the method; this can mislead engineers because selectivity, isotropy, and tool requirements differ significantly.
Terminology must stay consistent across datasheets, design kits and patent filings. A single inconsistent parameter can propagate into fabrication decisions or weaken a patent claim, and IP confidentiality applies to every document in the chain.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
