What this category of data looks like
Semiconductor investment research data mainly comes from public industry research reports, wafer fab financial reports, device specification sheets, patent documents, and supply chain statistics. Update cycles are inconsistent. Industry research reports are released weekly or monthly. Quarterly financial reports are updated per calendar quarter. Device specification sheets are updated irregularly as process nodes iterate. Most documents are long-form, with structured tables, electrical formulas, and technical terms. Fields include process nodes, power consumption, voltage, yield, and other metrics. Units are standard industry units such as nanometers (nm), watts (W), volts (V), and percentages (%).
What constraints do these characteristics impose on the document parsing and chunking stage
The multi-table, multi-formula nature of semiconductor documents requires the parsing stage to preserve the integrity of structured content, and avoid splitting parameter tables and formula combinations that span pages. Dense distribution of technical terms and bound units requires that chunking does not separate combined content such as "7nm process" or "1.8V operating voltage". Long-form documents have clear chapter logic, so splitting should follow chapter boundaries instead of fixed character counts, to prevent disruption of industry logical connections. Inconsistent update cycles also require the parsing stage to support incremental identification of updated document fragments, reducing repeated parsing costs.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Semiconductor documents contain a large number of wafer parameter and supply chain tables. Enabling this option preserves table row and column structures, avoiding chaotic parsed content |
PARSE_FORMULA_MODE | Preserve semantic format | Semiconductor documents contain a large number of electrical formulas and process parameter formulas. Preserving semantic format prevents formula logic from breaking after chunking |
max_chunk_tokens | 800–1200 characters | Balances technical term density and contextual association, avoiding splitting cross-page professional parameter combinations |
chunk_overlap | 150–200 characters | Covers cross-block associations of semiconductor terms, preventing separation of continuous descriptions such as process and yield |
PARSE_FILE_TIMEOUT | 600 seconds | Adapts to parsing of long documents with dozens of pages, avoiding timeout when parsing large-volume research reports |
ENABLE_INCREMENTAL_PARSE | Trigger based on update time | Adapts to inconsistent update cycles of semiconductor research reports and financial reports, only parsing updated document fragments |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. Testing using locally sourced samples is recommended before finalizing configuration.
Three common mistakes
- Phenomenon: A
504 Gateway Timeouterror is returned when parsing semiconductor documents, and the parsing progress is interrupted early. Cause: ThePARSE_FILE_TIMEOUTconfiguration is not adjusted, and the default timeout period is insufficient to complete the parsing process of long documents with dozens of pages. - Phenomenon: Professional parameter text embedded in images cannot be recalled during question-and-answer testing, only image links are displayed. Cause: The
PARSE_IMAGE_ENABLEconfiguration is not enabled, and image OCR text extraction is not triggered, so valid information in images is not included in chunking. - Phenomenon: Terms such as "3nm" and "process" appear separated in different chunks in the chunk list. Cause:
chunk_overlapis not set or the value is too small, and term association parsing is not bound, resulting in separation of numerical values and units.
How to confirm the configuration is correct
- Upload a segment of a semiconductor research report containing wafer parameter tables and electrical formulas. Verify that the parsed result retains complete table row and column structures and formula semantics.
- Review the chunk list. Confirm that continuous technical term combinations such as "5nm FinFET process" are not split into different chunks.
- Upload a document with embedded parameter images. Confirm that the parsed result includes text extracted from images, instead of only retaining image links.
- Upload a copy of a previously parsed semiconductor document. Modify the document content and re-upload. Confirm that only new content is re-parsed, and old document fragments are not processed repeatedly.
Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
