Discover device behavior laws, thermal dissipation equations, and process-yield relationships from semiconductor characterization data.
One of 34 industries across 8 sectors served by CDE — the Causal Dynamics Engine for Science and Engineering.
The Challenge
Why Semiconductor & Electronics teams still struggle to explain what is happening
Semiconductor device development generates high-precision characterization data (I-V curves, capacitance-voltage profiles, thermal imaging, process monitoring telemetry) spanning thousands of parameters across fabrication steps. The governing physics of device behavior is well understood in isolation, but interactions between process variables, material properties, and device performance create compound dependencies that resist manual analysis. Engineering teams spend months fitting empirical models, often missing non-obvious cross-parameter relationships that determine yield, reliability, and performance margins at advanced nodes where process tolerances narrow with each generation.
Design-of-experiments frameworks and statistical process control assume linear or low-order interactions between process variables. These assumptions break down at advanced nodes, where lithography, deposition, etch, and anneal steps produce emergent coupling effects that pairwise analysis cannot capture. TCAD simulations offer insight but require extensive calibration to each process variant and cannot easily incorporate real-time fab data. The gap between simulation fidelity and empirical manufacturing reality widens with each technology generation.
The CDE Approach
How CDE closes the explanation gap in semiconductor & electronics
CDE profiles raw characterization and process data, then discovers governing equations of device behavior directly from measurements. Its discovery modes explore the space of possible mathematical relationships between process parameters and device characteristics, surfacing cross-parameter dependencies that manual analysis routinely misses. Every discovered relationship is a typed scientific claim with confidence bounds and full provenance linking each equation to its source measurements.
Symbolic mode extracts closed-form equations for device characteristics, thermal dissipation laws, and process-yield relationships that engineers can validate against physical intuition. Neuro-Symbolic mode handles high-dimensional parameter spaces of modern processes, capturing complex interactions through the engine's internal methods before structure extraction yields interpretable governing laws. The Evidence Ledger provides deterministic replay and full provenance, meeting documentation standards for process qualification and technology transfer.
Discovery Engine
How CDE applies here
Symbolic discovery excels at extracting closed-form device physics equations for design rules and compact model development. Neuro-Symbolic mode addresses high-dimensional process optimization where hundreds of interacting parameters defy purely symbolic approaches. Causal mode maps causal pathways between process steps and yield outcomes, enabling targeted improvements rather than costly full-factorial experiments. The Truth Dial lets teams set confidence thresholds appropriate to each stage of process development.
Causal Graphs
Discovers directed causal structure from observational data — identifiable causal graphs, regime classifications, and intervention predictions.
Governing Equations
Extracts compact governing laws grounded in the causal structure — interpretable equations your team can read, verify, and compare against known theory.
Intervention Design
Proposes targeted experiments to resolve ambiguous causal edges — maximizing information gain where the causal structure is still uncertain.
Causal Validation
Negative controls, falsification tests, and identifiability analysis applied to every causal claim before promotion to the evidence ledger.
Typed Scientific Claims
What CDE discovers
Every discovery CDE produces is a typed scientific claim — not a black-box prediction, but a governed, reproducible, auditable piece of scientific knowledge with full provenance.
- Device characteristic equations
- Thermal management laws
- Process-yield governing relationships
- Defect formation dynamics
- Scaling behavior models
Governed Discovery
Make the finding reviewable
Every discovery CDE produces carries the review context around it: a Truth Dial setting, an evidence entry with replay context, and control results including bootstrap stability, out-of-distribution testing, and feature-shuffle validation.
For semiconductor & electronics, that means teams can compare runs, justify decisions, and decide whether a finding is ready for internal use, external review, or regulated submission.
