Building a Strategic Semiconductor Capacity
1. What It Takes to Make Chips
The Semiconductor Manufacturing Process (Simplified):
1. Chip Design
- Engineers Design Circuit: Using specialized software (EDA tools)
- Simulation: Test design virtually before manufacturing
- Mask Creation: Convert design to photomasks (templates for chip layers)
2. Wafer Fabrication ("Fab")
- Silicon Wafer: Start with ultra-pure silicon disc (12 inches diameter)
- Photolithography: Use UV light to etch circuit patterns (like photography, but nano-scale)
- Deposition: Add layers of materials (conductors and insulators)
- Etching: Remove unwanted material (create transistors and wires)
- Doping: Add impurities to control electrical properties
- Repeat: 50-100+ layers to create complex circuits
- Result: One wafer has hundreds of chips
3. Testing & Packaging
- Test Each Chip: Identify defects (30-70% yield is normal for cutting-edge chips)
- Cut the Wafer: Separate individual chips ("dies")
- Package: Encase chip in protective casing with connectors
- Final Test: Ensure packaged chip works
4. Assembly into Products
- Circuit Boards: Chips soldered onto boards
- Integration: Boards assembled into phones, computers, cars, etc.
2. The Infrastructure Required
What We Need to Build:
1. Fabrication Plants ("Fabs")
Current State:
- US Has ~30 Fabs (mostly older technology, 10nm+ nodes)
- Advanced Fabs: Only Intel has a few 7nm/5nm fabs (behind TSMC's 3nm)
What "Advanced" Means:
- Node Size: 3nm, 5nm, 7nm (smaller = more transistors per chip = more powerful, efficient)
- TSMC 3nm: Most advanced commercially available (used in iPhone 15, newest chips)
- Intel Is Stuck at 7nm: Years behind (technological failure)
Target Capacity:
Minimum Strategic Reserve:
- 10 Advanced Fabs (3nm-5nm capability)
- Each produces ~100,000 wafers/month
- Total: 1 million wafers/month = ~10 billion chips/year
- Enough for: Critical needs (military, medical, and infrastructure) if Taiwan is cut off
Robust Domestic Industry:
- 30 Advanced Fabs (match Taiwan's capacity)
- 3 million wafers/month = 30 billion chips/year
- Enough for: Near self-sufficiency (still import some commodity chips, but not dependent)
Budget:
Per Fab Cost:
- Cutting-edge (3nm): $20-30 billion each (TSMC's Arizona fab = $40 billion for latest tech)
- Mature (7nm): $10-15 billion each
- Older (28nm+): $5-10 billion each
Strategic Reserve (10 Fabs):
- Mix of Technologies: 3 cutting-edge (3nm) + 4 mature (7nm) + 3 older (28nm)
- Cost: (3 × $25B) + (4 × $12B) + (3 × $7B) = $75B + $48B + $21B = $144 billion
Robust Capacity (30 Fabs):
- Mix: 10 cutting-edge + 12 mature + 8 older
- Cost: (10 × $25B) + (12 × $12B) + (8 × $7B) = $250B + $144B + $56B = $450 billion
2. Equipment & Materials
Specialized Equipment Needed:
Lithography Machines:
- Extreme Ultraviolet (EUV): Required for 3nm-7nm chips
- Only Supplier: ASML (Dutch company, monopoly!)
- Cost: $150-200 million per machine
- Lead Time: 2-3 years to build one
- US Dependence: Must buy from ASML (or develop own, which would take 10+ years)
Other Critical Equipment:
- Deposition Tools: Apply thin films (Applied Materials, US company)
- Etching Systems: Remove material (Lam Research, US company)
- Ion Implanters: Dope silicon (Axcelis, US company)
- Metrology: Measure nano-scale features (KLA, US company)
Total Equipment Cost per Fab:
- Cutting-Edge: $8-12 billion (EUV machines + supporting equipment)
- Mature: $4-6 billion
- Older: $2-3 billion
Materials:
- Ultra-Pure Silicon: Grown as single crystals, sliced into wafers
- Chemicals: Hundreds of ultra-pure chemicals (photoresists, etchants, and dopants)
- Gases: Ultra-high-purity gases (nitrogen, argon, silane, etc.)
- Water: Billions of gallons of ultra-pure water (18 megohm-cm resistivity)
Material Costs: Included in fab operating costs (~$2-5 billion/year per fab)
3. Human Capital
Workforce Needed:
Per Advanced Fab:
- Engineers: 1,000-2,000 (process, equipment, design, and test)
- Technicians: 2,000-4,000 (operate equipment, maintain cleanrooms)
- Support Staff: 500-1,000 (logistics, admin, security)
- Total per Fab: 3,500-7,000 workers
For 30 Fabs:
- Total Workforce: 105,000-210,000 workers (let's say 150,000 average)
Skills Required:
- Electrical Engineering: Circuit design and process engineering
- Materials Science: Thin films, crystallography, and doping
- Physics: Optics (lithography) and quantum mechanics
- Chemistry: Cleanroom processes, etching, and deposition
- Mechanical Engineering: Equipment design and maintenance
- Software Engineering: Automation, testing, and design tools
Training Pipeline:
Current Problem:
- Limited Programs: Few US universities have semiconductor programs (shut down in 1990s-2000s)
- Talent Shortage: 67,000 semiconductor job openings in US (can't fill them)
- Knowledge Loss: Engineers who built 1980s fabs are retired/dead
Solution:
National Semiconductor Workforce Program:
- University Partnerships: Fund 50 universities to create/expand semiconductor programs
- Budget: $5 billion (endowments for programs, equipment, faculty)
- Community College Training: 200 community colleges offer technician programs
- Budget: $2 billion (equipment and curriculum development)
- Apprenticeships: On-the-job training at fabs (2-year programs)
- Guarantee: Every apprentice hired full-time after completion
- Wage: $60k during apprenticeship, $80k+ after
- K-12 Pipeline: STEM education focused on materials science, engineering
- Budget: $1 billion/year (integrated with the platform's education policy)
Total Workforce Development: $10 billion over 10 years
4. Supply Chain
Critical Inputs:
Silicon Wafers:
- Current Suppliers: Japan (Shin-Etsu, SUMCO), Germany (Siltronic), and Taiwan (GlobalWafers)
- US Capacity: Minimal (GlobalWafers building plant in Texas, but not enough)
- Need: 3-5 wafer manufacturing plants in US
- Cost: $5 billion each × 4 plants = $20 billion
Chemicals:
- Current Suppliers: Japan, Europe (BASF, Merck), and some US (DuPont, Honeywell)
- Need: Expand US chemical production for semiconductor-grade purity
- Cost: $10 billion (new production facilities)
Gases:
- Current Suppliers: Mostly US (Air Liquide, Linde, and Air Products)
- Need: Expand capacity for ultra-high-purity gases
- Cost: $5 billion
EUV Lithography Machines:
- Critical Bottleneck: ASML (Netherlands) only supplier
- Options:
- A. Buy from ASML: Pay $150-200M per machine (ongoing dependence)
- B. Develop an US Alternative: 10-15 year R&D project, $50+ billion (risky, slow)
- C. Joint Venture with ASML: Co-develop next-gen machines (share tech and reduce dependence)
- Recommended: Option C + stockpile Option A machines as backup
Total Supply Chain Investment: $35 billion
3. Timeline to Build Capacity
Realistic Timeline for Strategic Reserve (10 Fabs):
Years 1-3: Planning & Site Preparation
- Site Selection: Identify 10 locations (need water, power, and access to a skilled workforce)
- Environmental Review: NEPA compliance (can be streamlined for national security)
- Infrastructure: Build roads, power substations, and water treatment
- Workforce Recruitment: Begin university/community college programs
- Equipment Orders: Place orders for EUV machines (2-3 year lead time)
Years 4-6: Construction
- Fab Construction: 2-3 years to build cleanrooms, install equipment
- Parallel Development: All 10 fabs start construction simultaneously (not sequentially)
- Equipment Installation: As buildings complete, install tools
- Workforce Training: Engineers/technicians train at existing fabs, equipment vendors
Years 7-8: Ramp-Up
- Process Development: Fine-tune manufacturing processes (each fab takes 1-2 years to reach full yield)
- Qualification: Test chips meet specs, certify for customers
- Volume Production: Scale from pilot to full production
Year 9-10: Full Operation
- All 10 Fabs Producing: 1 million wafers/month capacity achieved
- Meets Strategic Reserve: US can sustain critical chip needs without Taiwan
For 30 Fabs (Robust Capacity):
- Years 1-10: Build first 10 (as above)
- Years 8-15: Build second wave of 10 (lessons learned from first wave)
- Years 13-20: Build third wave of 10 (by now, process is streamlined)
- Year 20: Full 30 fabs operational
