MECM90041 Chap.9 Chips, Supply Chains and Technological Sovereignty

Chips, Supply Chains and Technological Sovereignty

The semiconductor ecosystem separates design, software, intellectual property, equipment, fabrication, packaging and use. Bottlenecks gain political force where substitution, qualification and maintenance are slow.

Export controls and reshoring redistribute risk rather than create binary self-sufficiency. Sovereignty rests on knowledge, supply, governance and recovery.

The lecture's six final dimensions include data, algorithms, markets, supply, military advantage and regional power projection.

Chapter guide expansion. · C9 · CHIP ECOSYSTEM CHAPTER 9 · PAGE 1 WEEK 5 · APPLIED CASE Semiconductors make digital sovereignty concrete Design, fabrication and equipment form an interdependent ecosystem The semiconductor block is the subject’s most concrete political-economic case.

A chip is not produced by one vertically complete actor. Design, intellectual property, electronic-design software, fabrication, specialised equipment, testing, packaging and assembly form an ecosystem distributed across firms and jurisdictions. Concentration at one stage can create leverage over the whole chain.

design equipment fabrication packaging end use each stage has its own upstream dependencies demand and control feed back through the chain Figure 9.1. A rebuilt supply chain shows sequential production and feedback from demand, control and upstream dependency. Ecosystem stages Stage Capability Dependency question Design Architecture and product specification Which tools and intellectual property are licensed?

Equipment Machines for fabrication processes Which suppliers are irreplaceable? Fabrication Manufacture at a process node Where are capacity and yield concentrated? Packaging / testing Connect, protect and verify chips Which labour and facilities complete the product? End use Phones, servers, vehicles and systems Which demand shapes investment?

Upstream and downstream are directional Design and equipment are upstream of fabrication; end-use demand is downstream while feeding investment back upstream. A bottleneck is relational Concentration matters when substitutes, inventories, time and qualification requirements make disruption consequential. A supply chain becomes political when dependence can be converted into leverage.

APPLIED PRINCIPLE C9.1 CHAIN TRACE AskSia practice Prompt. A country can package chips but not fabricate them. Is it sovereign? Worked answer. Map design, tools, fabrication, materials and demand; one domestic stage does not remove dependencies elsewhere.

· · C9 · NODE CAPABILITY CHAPTER 9 · PAGE 2 CAPABILITY SCALE Node size is a capability scale, not a quality ranking Different end uses require different fabrication capacities The deck maps fabrication node sizes to end uses, from advanced nodes used in phones, AI systems and servers to coarser nodes used in vehicles and radar. Smaller nominal nodes are not simply “better chips” for every purpose.

Performance, power, reliability, cost, environmental tolerance and supply availability differ by application. Political-economic capacity concerns the portfolio of functions a system can support.

Read capability by use Application Relevant demand Why newest may not dominate AI accelerator High compute and energy efficiency Cost, memory and packaging still constrain Phone Performance within battery and space limits Integrated design and scale matter Vehicle Reliability, qualification and long life Mature nodes may be preferred Radar / industrial Durability and specialised performance Extreme miniaturisation may add little value Node labels are commercial and technical Do not treat the number as a literal universal measurement across manufacturers without context.

Generation lag is strategic A country may expand mature-node capacity yet remain dependent for frontier applications. Specify the use. CAPABILITY TEST CAPABILITY = node + design + yield + packaging + use NOT NODE NUMBER ALONE C9.2 SCALE REPAIR AskSia practice Prompt. Repair: “Larger-node chips are obsolete.” Worked answer.

Identify application, reliability, cost and supply requirements; mature processes remain essential for many systems. · · C9 · FOUNDRIES CHAPTER 9 · PAGE 3 FOUNDRY MODEL Foundries and fabless firms separate design from manufacture Specialisation creates scale and dependence The foundry model lets firms design chips without owning fabrication plants, while specialist foundries manufacture designs for many customers.

This separation lowers one entry barrier but raises dependence on a small number of capital-intensive producers and toolchains. Market-share figures in the lecture are data about concentration, not assessment weights; the important task is to explain how concentration becomes operational power.

Political economy of specialisation Actor Gain Exposure Fabless designer Avoids fabrication capital and gains specialist capacity Depends on tools, foundry slots and export permissions Foundry Scale, learning and diverse demand Requires huge investment, equipment and stable utilities Integrated manufacturer Coordinates design and fabrication Carries capital cost and may lag specialist ecosystems Customer state / firm Accesses advanced products Faces external capacity
