PDK Updates Required: - New RibbonFET device models (TCAD validated) - PowerVia implementation guidelines - Updated EM/IR rules for backside power - DRC deck for 18A design rules 3. Design Optimization Opportunities: - Area Scaling: 30% density improvement → smaller die, more dies/wafer - Power Reduction: Same performance at 20% lower power → better battery life - Frequency Boost: Push clocks 10-15% higher for performance segments 4. Validation Considerations: - New process corner models (RibbonFET variability) - PowerVia signal integrity analysis - Thermal analysis (different self-heating characteristics) 5. Schedule Impact: - PDK 1.0 available: Now - Risk production: Q2 2025 - Volume production: H2 2025 - Recommended tape-out: Q3 2025 for H1 2026 product launch Recommendation: Start with test chips to validate critical IPs (SRAM, PLL, high-speed IO) before full SoC migration.

Intel Engineer:

IDM 2.0 Balancing Framework: Core Principle: Manufacturing assets must be financially sustainable. - Under Lip-Bu Tan: Foundry P&L separate from Product P&L - Internal products pay market rates (arm's length transactions) - External customers get equal access and service Capacity Allocation: | Priority | Allocation | Criteria | | --- | --- | --- | | 1. Strategic products | 40% | Panther Lake, Xeon 6, Gaudi 3 | | 2. Foundry customers | 35% | Committed capacity, long-term agreements | | 3. Technology development | 15% | Process learning, yield ramp | | 4. Buffer/Flex | 10% | Demand surge, opportunistic | Decision Framework: `` Internal Product Request vs. Foundry Customer Conflict? ├── Is product launch date committed to market? │ ├── Yes → Prioritize product (revenue impact) │ └── No → Evaluate foundry customer contract terms ├── Is foundry customer strategic (multi-year commitment)? │ ├── Yes → Negotiate compromise (split lots, delayed ramp) │ └── No → Product priority, offer later capacity └── Can capacity be expanded? ├── Yes → Invest in expansion (if ROI positive) └── No → Auction to highest strategic value `` Key Metrics: - Foundry revenue growth (target: $10B+ by 2026) - Capacity utilization (target: >90% for mature nodes, >70% for leading edge) - Customer NPS (foundry customer satisfaction) - Product margin (even with internal pricing) Current Strategy (2025): - Intel 18A: Internal products first (Panther Lake, Clearwater Forest) - External customers: Tape-out H1 2026, production H2 2026 - This de-risks process for external customers - Builds foundry credibility with proven production data Financial Discipline: - Cancelled Germany/Poland fabs (cost reduction) - Slowed Ohio construction (match demand) - 14A node: No development without external customer commitments - Focus: 18A execution excellence before next node investment
