Dielectric介电层
A dielectric is an insulating material placed between conductive structures—such as metal lines, capacitor plates, or gate electrodes—to prevent unintended current flow, avoid shorting, and provide the capacitance required for device operation. In semiconductor documentation it appears in cross-sectional diagrams, process integration notes, material specifications, and reliability reports that describe interlayer insulation, gate stacks, and leakage performance.

Where this term appears
Dielectric appears in process integration documents, material datasheets, cross-section annotations, and reliability qualification reports. Localizers encounter it when translating equipment manuals, layer stack tables, and failure analysis summaries, where low-k or high-k dielectrics must be distinguished from passivation or photoresist; the source text may also use the term for gate, intermetal, or shallow-trench isolation layers.
Translation checks
A common mistake is translating dielectric generically as insulator everywhere, which loses the material-specific capacitance and integration role. Mixing up low-k and high-k dielectrics is more serious because the intended electrical behavior is opposite, and the error can invert a reliability or performance statement in a qualification report.
Keep the term aligned across your files
Technical terms need checking against the source, approved product terminology and related specifications. Keep units, parameter conditions and document versions aligned across the file set.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
