Semiconductor Sti Corner Parasitic Transistor Threshold Calculator
Audit actual matched corner/planar transistor thresholds and caller parasitic drop criterion, no generic narrow-width coefficient or inferred parasitic conduction.
Description
An STI-corner threshold can differ from a matched planar-transistor threshold.
An STI-corner threshold can differ from a matched planar-transistor threshold.1
A signed difference distinguishes a lower corner threshold from a higher one before a caller drop criterion is applied.
When to use Semiconductor Sti Corner Parasitic Transistor Threshold Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
How to use Semiconductor Sti Corner Parasitic Transistor Threshold Calculator and understand its results
- Prepare measured device or specimen records under independently matched branch, temperature, frame, and unit conventions.
- Enter observedPlanarThresholdV, observedStiCornerThresholdV, callerMaximumCornerThresholdDropV, following the field table and rules below, then run the tool.
- Read signedStiCornerMinusPlanarThresholdV, cornerThresholdDropReviewIndices. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedPlanarThresholdV | Observed planar threshold v | list of number | Required |
| observedStiCornerThresholdV | Observed STI corner threshold v | list of number | Required |
| callerMaximumCornerThresholdDropV | Caller maximum corner threshold drop v | number | Required |
Use aligned nonempty finite planar and corner thresholds in volts and a nonnegative maximum allowed drop. Return corner minus planar and indices where the negative of that difference strictly exceeds the caller maximum.
shift_i=corner_i−planar_i; review_i=(−shift_i)>maxDrop Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedStiCornerMinusPlanarThresholdV | Signed STI corner minus planar threshold v | list of number |
| cornerThresholdDropReviewIndices | Corner threshold drop review indices | list of number |

}Limitations and assumptions
Matched measurement branch, material state, calibration, and conventions must be independently established. Results do not certify device performance or operating conditions.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above.
Alternative or Complementary methods
For a related review, use Semiconductor Shallow Trench Isolation Stress Calculator: A reduced elastic stiffness matrix maps three strain components to three stress components in a declared local convention. Its component and shear conventions must match the supplied strain vector. For a complementary step, use Semiconductor Retrograde Well Profile Calculator: A retrograde-well profile can be summarized by measured peak concentration, its depth ties, and contrast with a supplied reference depth. That reference must already represent the intended surface.
