LESSON PACKET / SA-PWR-GAN-SIC-002

Substrate choice changes the whole GaN HEMT evidence chain.
Power / Device

Semi-insulating SiC is not just a material badge. This packet keeps substrate resistivity, thermal path, GaN buffer traps, HEMT mode, dynamic Ron, package heat path, reliability stress, and application fit in one bounded replay.

EVIDENCE SEQUENCE

What the learner should inspect first.

This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.

01

Start with substrate profile: semi-insulating SiC, high-resistivity SiC scale-up, GaN-on-Si cost reference, or bonded GaN-SiC interface watch.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
02

Add buffer strategy, HEMT mode, thermal stack, reliability context, and application target before reading the application-fit score.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
03

Use the decision gate to decide whether thermal path, buffer traps, dynamic Ron, normally-off reliability, interface TBC, or cost-scale evidence is missing.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

METHODS

Precomputed model contract.

The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.

method

Original synthetic GaN-on-SiC pathfinding table based on public WBG, RF GaN, thermal, and reliability vocabulary.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

No epitaxy recipe, wafer process setting, RF simulator, TCAD deck, vendor table, or measured wafer data is copied.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

The browser filters saved CSV rows and exposes the model card with no-live-solver and no-product-recommendation boundaries.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

LIMITS

Useful, but deliberately bounded.

No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.

non-claim

No process recipe, gas flow, wafer specification, equipment control, supplier ranking, product recommendation, or reliability qualification.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

No live TCAD, electrothermal solver, RF simulator, SPICE, uploaded design, account, payment, comment, newsletter signup, job/event workflow, or public service intake.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

Real work needs owned thermal, RF, dynamic Ron, buffer trap, gate-stack, package, and mission-profile evidence before claims are reused.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

SOURCE ANCHOR

Link-only public source spine.

SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
