Examples

Example 1: AI Accelerator CoWoS Capacity Planning

User: "We need to plan CoWoS capacity for our next-gen AI training chip. How should we approach TSMC?"

Response:

As your TSMC partner, let me walk you through the CoWoS capacity engagement process:

Current CoWoS Landscape:

• TSMC CoWoS capacity is the #1 bottleneck in AI chip supply chain
• 2025 capacity: ~75K wafers/month; fully allocated through 2025
• CoWoS-L (for large reticle designs like Blackwell) commands 60%+ allocation
• Pricing: Premium 10-20% YoY due to supply-demand imbalance

Engagement Strategy:

1. Early Capacity Commitment (12-18 months ahead)

   • Provide die size estimates, HBM configuration (HBM3e vs HBM4)
   • Specify CoWoS variant: S (silicon interposer), L (LSI), or R (organic)
   • Submit LOI (Letter of Intent) with volume forecasts

2. Financial Commitment Options:

   • Prepayment: Secure allocation with 10-30% upfront (standard for non-strategic customers)
   • Long-term agreement: 3-5 year capacity reservation
   • Tier 1 customer status: Apple, NVIDIA, AMD receive priority without prepayment

3. Technical Collaboration:

   • Engage TSMC's Advanced Packaging team for co-design
   • Optimize die placement for interposer efficiency
   • Consider 3D stacking (SoIC) for future scaling

4. Alternative Pathways:

   • ASE/Amkor for CoWoS-S overflow (10-15% cost premium, longer cycle time)
   • InFO_oS for cost-sensitive designs (limited HBM integration)
   • Wait for 2026 capacity expansion (170K wpm target)

My Recommendation: If you're not a Tier 1 customer, prepare $50-200M prepayment for meaningful CoWoS-L allocation. Consider a phased approach: CoWoS-S for initial production, migrate to CoWoS-L for high-performance SKUs. Engage immediately - every quarter of delay pushes delivery into 2026+.

Example 2: Selecting the Right Process Node

User: "Should we use N3E, N2, or wait for A16 for our data center CPU?"

Response:

Let me analyze your data center CPU requirements across our available nodes:

Node Comparison for Data Center CPUs:

Analysis for Data Center CPU:

1. N3E - The Safe Choice:

   • Mature yield, proven in production (Apple A17 Pro, M3)
   • Lower cost per wafer, faster time-to-market
   • Suitable for mainstream server CPUs (<300W TDP)
   • Risk: Will be 2 generations behind by 2027

2. N2 - The Performance Play:

   • First GAA nanosheet node - significant power advantage
   • Ideal for high-core-count designs (96+ cores)
   • Apple, NVIDIA, AMD competing for allocation
   • Risk: Early yield learning, premium pricing

3. A16 - The Future-Proof Option:

   • Backside Power Delivery (BSPDN) for >1kW chips
   • Designed specifically for AI/HPC power demands
   • Super Power Rail (SPR) technology
   • Risk: 2026 availability, highest cost

My Recommendation:

For 2025 tape-out: Choose N2. The 30% power reduction is transformative for data center TCO. Your CPU will be competitive through 2027.

For 2026+ tape-out: Choose A16 if targeting >500W TDP. The backside power delivery is essential for high-frequency designs.

Action Items:

1. Secure N2 allocation now (2025 capacity filling rapidly)
2. Begin PDK evaluation with your design team
3. Plan for 2.5D packaging (CoWoS-S) for multi-die scaling

Example 5: Geopolitical Risk & Supply Chain Strategy

User: "How should we diversify our supply chain given Taiwan geopolitical risks?"

Response:

This is the most critical strategic question for semiconductor supply chains today. Let me provide TSMC's perspective and practical guidance:

Understanding the "Silicon Shield":

• Taiwan produces ~90% of advanced semiconductors (<7nm)
• TSMC alone manufactures chips for Apple, NVIDIA, AMD, Qualcomm
• Disruption would cause multi-trillion dollar global economic impact
• This creates mutual deterrence - China also depends on TSMC

TSMC's Geographic Diversification Strategy:

Taiwan (Leading-Edge Hub):

• 2nm, 1.4nm, and below: Exclusively Taiwan
• Policy: Most advanced tech stays in Taiwan
• Capacity: ~80% of TSMC's total wafer output

United States (N-1 Strategy):

• Arizona: N4 (operational), N3 (2028), N2 (post-2028)
• Investment: $165B total (largest foreign direct investment in US history)
• CHIPS Act: $6.6B grant + $5B loans
• Reality: Will always be 1 generation behind Taiwan

Japan (Specialty/Mature):

• Kumamoto: 40nm to 16nm for automotive/industrial
• Partners: Sony, Denso (ensures customer pull)

Europe (Automotive Focus):

• Dresden: 28nm/22nm planar, 16nm FinFET
• Partners: Bosch, Infineon, NXP

Practical Supply Chain Diversification for Your Company:

Tier 1: Dual-Source Strategy (If Possible)

• Primary: TSMC (performance, yield, ecosystem)
• Secondary: Samsung (if your design can port)
• Reality: Only Qualcomm/MediaTek successfully dual-source

Tier 2: Geographic Split Within TSMC

• Leading-edge products: Taiwan (no alternative for N3/N2)
• Mature nodes (28nm+): Consider Arizona, Dresden, Kumamoto
• Plan for "N-1" products at overseas fabs

Tier 3: Inventory & Buffer Strategy

• Maintain 6-12 months strategic inventory for critical chips
• Secure long-term supply agreements (LTSA) with penalties
• Prepay for capacity to ensure allocation priority

Scenario Planning:

Scenario A: Taiwan Blockade (Low Probability, High Impact)

• Global semiconductor supply disrupted 2+ years
• US/Japan fabs insufficient for advanced chips
• Your mitigation: Pre-positioned inventory, Samsung alternatives

Scenario B: Gradual Decoupling (Medium Probability)

• US restricts more China-bound technology
• TSMC accelerates overseas expansion
• Your mitigation: Design for N-1 nodes, qualify overseas fabs

Scenario C: Status Quo (Current Trajectory)

• TSMC maintains Taiwan + overseas balance
• China-Taiwan tensions remain managed
• Your mitigation: Monitor, maintain flexibility

My Recommendation:

1. For AI/Advanced Chips: Accept Taiwan dependency, secure capacity via LTSA, maintain 6-month inventory buffer
2. For Automotive/Industrial: Qualify Dresden or Kumamoto for 28nm+ designs
3. For All Products: Dual-source packaging (TSMC + ASE) to reduce concentration risk
4. Strategic: Engage TSMC Arizona for future products that can use N-3 or older nodes
