Workhorses: The essential, high-volume chips and back-end services that turn advanced semiconductor capability into reliable products used every day.
Understand the Semiconductor Industry in Four Pillars
Semiconductors power AI, data centers, smartphones, vehicles, industrial equipment, and much of the modern economy. But the industry can feel impossible to follow when headlines jump between Nvidia, TSMC, ASML, chip shortages, tariffs, export controls, and earnings.
The Four Pillars gives you a simple framework for understanding how the semiconductor ecosystem fits together—from the companies that build chip-making tools to the chips inside real-world products.
No engineering degree. No technical background. Just a practical way to understand the sector with confidence.
What You’ll Walk Away With
After completing all four weeks, you will be able to:
Explain how the semiconductor supply chain moves from manufacturing equipment and design to finished chips and real-world products.
Classify most semiconductor companies by their primary role in the ecosystem—and recognize major companies that operate across more than one role.
Understand why chip shortages, capacity constraints, and supply-chain disruptions happen—and where they begin.
Read semiconductor news, earnings reports, and industry headlines with genuine context.
Follow the geopolitics of chips, including why manufacturing capacity, export controls, and regional supply chains matter.
Apply the Four Pillars framework to new companies, industry developments, and market trends.
Better understand why the same headline may affect semiconductor stocks and ETFs in very different ways.
Course Format
Self-paced: Complete the material on your own schedule.
Four weeks: One pillar per week, with approximately 1–2 hours of learning each week.
Practical: Real companies, recognizable examples, and plain-English explanations throughout.
Progress-based: A milestone checklist at the end of each week helps you confirm the key ideas before moving on.
Beginner-friendly: No technical or financial background required.
The Four Pillars
Week 1 — Toolmakers
Learn where chip-manufacturing capability comes from: the equipment, inspection, materials, and systems that make advanced fabrication possible.
Week 2 — Architects
Learn who designs chips, who creates the software and intellectual property behind those designs, and why design leadership matters.
Week 3 — Foundries
Learn how designs become physical chips, why manufacturing capacity matters, and why a handful of leading foundries have outsized global importance.
Week 4 — Workhorses
Learn about the essential chips that keep everyday systems operating—from power and analog chips to memory, industrial semiconductors, and the companies that bring finished chips to market.

One important curriculum note
I would be cautious about defining Workhorses too broadly until we lock down exactly what it means in your teaching model. Packaging and testing are generally a separate back-end activity—often performed by OSAT companies—while “workhorse” chips commonly implies analog, power, microcontrollers, memory, and mature-node components. Those are all important, but they are not exactly the same category.
