What This Category of Data Looks Like
Semiconductor investment research data primarily comes from fab process specification documents, EDA design output files, industry association supply and demand reports, and brokerage sector research reports. Update cadences vary significantly: process documents update quarterly to annually, industry supply and demand data updates monthly, and research reports are released irregularly alongside industry events. Document structures include long-form technical descriptions, structured parameter tables, and semi-structured supply and demand statistics items. Common fields include process nodes, single-batch production capacity, timing parameters, and voltage thresholds. Units include nanometers, wafers per month, nanoseconds, volts, and others.
What Constraints Do These Characteristics Impose on Context and Token Handling
Long-form process documents have high per-document token usage, which easily exceeds the model’s preset context window limit. This leads to document truncation or retrieval failure. If multi-column fields in structured parameter tables are not properly split, token redundancy or broken cross-field context associations will occur. Data with different update cadences must be matched with corresponding retrieval priorities. This prevents outdated data from occupying excessive token quotas. High-precision process and timing parameters require complete numerical precision. Truncation will reduce the accuracy of investment research analysis.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 1000–1500 characters | Adapts to long-form text and structured tables in semiconductor documents, balancing per-block token usage and context relevance |
recallTopK | Top 3–5 results | Semiconductor investment research requires linking multi-dimensional parameters. Excessive recall will exceed token quotas |
similarityThreshold | 0.72–0.85 | Semiconductor parameters have high precision requirements. A threshold that is too low will introduce irrelevant data, while one that is too high will miss valid parameters |
maxTokenPerChunk | 800–1200 tokens | Prevents per-block token usage from exceeding model limits, while preserving parameter integrity |
contextWindow | 32000–64000 tokens | Adapts to token usage from long-form process documents and multiple retrieved blocks |
overlapSize | 100–200 characters | Maintains parameter context associations across segments, avoiding field breaks after structured table splitting |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by data format, dataset size, and business rules. Specific issues require individual analysis, and it is recommended to test on the reader’s own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: After uploading a semiconductor production capacity Excel file with 10000+ rows, the system prompts that token usage has exceeded the quota, or field missing appears in segmented results. Cause: The
chunkSizeparameter was not adjusted. The default segment length does not adapt to the number of columns and rows in the structured table, leading to excessive per-block token usage. - Phenomenon: When calling the semiconductor process parameter retrieval interface, the
Reached the max retries per request limiterror is returned. Cause: Matching request parameters for high-precision parameters are redundant, exceeding the interface retry quota. - Phenomenon: When uploading a long-form EDA design document, the system prompts context window overflow, or the document is forcibly truncated. Cause: The
contextWindowparameter is set too small, failing to adapt to the token usage of long-form text.
How to Verify Correct Configuration
- Upload a single typical semiconductor process document, check the system-generated segment details to confirm that each block’s length and token usage match the configured settings.
- Initiate a simulated investment research query, verify that the number of retrieved results and matching accuracy align with preset rules.
- Check the system’s token usage logs to confirm that single conversation consumption matches the expected configuration.
- Upload multiple types of semiconductor documents (such as tables, long-form text, research reports) to verify that the segmentation and retrieval association logic works normally.
