Substrate衬底
A substrate is the base semiconductor wafer or material layer on which device fabrication and interconnect formation are performed. In technical translation, the term appears in wafer processing, packaging, and reliability documents to describe the starting material, the mechanical foundation of a die, the underlying layer in chip or package construction, and the base for epitaxial growth or interconnect stacks.

Where this term appears
In localization, the term substrate appears in process integration reports, epitaxy documentation, packaging drawings, thermal analysis reports, material compliance declarations, and semiconductor equipment manuals. It also occurs in wire-bond and flip-chip assembly instructions where the die, package substrate, and wafer starting material must be clearly distinguished to avoid incorrect material references in translated work orders.
Translation checks
A frequent error is using “baseboard” or “substrate board” without distinguishing the semiconductor wafer substrate from the package substrate. In assembly and reliability texts, this confusion makes it unclear which layer is affected by stress, delamination, or contamination, and can change the meaning of documented root-cause reports and corrective actions.
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.
