Forksheet Logic Weigh Industry Rd Status and Timelines Honestly

# Forksheet Transistors: Step 17 — Weigh Industry R&D Status and Timelines Honestly

## 1. What Public Disclosures Actually Say

Forksheet has appeared in public foundry and research-consortium roadmap disclosures as a node-over-node option under active development, generally discussed alongside, and slightly ahead of, full CFET integration in projected production timelines. As with `cfet_logic` Step 17's treatment of CFET, this series treats these disclosures as roadmap framing and projection, not as confirmed, locked production commitments.

## 2. Where Forksheet Sits Relative to CFET's Timeline

Because forksheet reuses more of nanosheet GAA's existing unit processes (Step 5) and requires a smaller standard-cell library change (Step 11) than CFET does, it has generally been projected to reach production readiness, if it does, somewhat earlier than full CFET integration — consistent with the bridge framing Step 15 of this series lays out. That relative ordering is more consistently reported across sources than any specific calendar date for either technology.

## 3. Why Specific Dates Are Treated Cautiously Here

Specific production-year projections for both forksheet and CFET have moved in public disclosures as process-development results have come in, the same pattern `cfet_logic` Step 17 notes for CFET. This series avoids stating a specific year as settled fact for forksheet for the same reason, preferring directional language — under development, being demonstrated, projected — throughout.

## 4. What Would Change This Assessment

The clearest signals that would firm up forksheet's production timeline are public disclosures of yield data at a specific target wall thickness (Step 10) and confirmation that a multi-device standard-cell library (Step 13) has been validated beyond test circuits — neither of which has been broadly disclosed as settled at the time of this series' authoring.
