Understanding the chips (semiconductor) industry requires a multi-faceted approach, as it is a complex, capital-intensive, and strategically important sector. Here’s a structured way to get started:
1. Industry Basics
What is a Semiconductor?
- Semiconductors are materials with electrical conductivity between conductors (e.g., copper) and insulators (e.g., glass).
- They form the foundation of microchips (integrated circuits - ICs), which power everything from smartphones to supercomputers.
Key Semiconductor Products:
- Logic Chips: CPUs, GPUs, AI accelerators (NVIDIA, AMD, Intel).
- Memory Chips: DRAM, NAND Flash (Samsung, Micron, SK Hynix).
- Analog Chips: Sensors, power management ICs (Texas Instruments, Analog Devices).
- Microcontrollers (MCUs): Used in embedded systems (STMicroelectronics, NXP, Renesas).
- Specialized Chips: ASICs (e.g., Google TPUs), FPGAs (e.g., Xilinx, Intel).
2. Supply Chain & Key Players
Global Supply Chain Segments
-
Chip Design
- Companies like Apple, Qualcomm, NVIDIA, AMD focus on design but don’t manufacture chips.
- They rely on Electronic Design Automation (EDA) tools from Synopsys, Cadence, and Siemens EDA.
-
Chip Manufacturing (Foundries)
- Only a few companies can fabricate advanced chips: TSMC (Taiwan), Samsung (Korea), Intel (USA).
- TSMC dominates with cutting-edge nodes (3nm, 5nm).
-
Materials & Equipment Suppliers
- Materials: Silicon wafers (Shin-Etsu, SUMCO), photomasks, gases, chemicals.
- Equipment: Extreme Ultraviolet Lithography (EUV) machines from ASML (Netherlands), etching/deposition from Applied Materials, Lam Research, Tokyo Electron.
-
Chip Packaging & Testing
- OSAT (Outsourced Semiconductor Assembly & Testing) players like ASE, Amkor handle packaging.
-
End-User Companies
- Tech firms: Apple, Google, Tesla, Microsoft.
- Automotive: Tesla, Toyota, Ford.
- IoT, consumer electronics, industrial automation.
3. Business & Market Trends
Market Structure
- Fabless Model: Qualcomm, NVIDIA design but outsource manufacturing.
- Foundry Model: TSMC, Samsung manufacture chips for others.
- IDM (Integrated Device Manufacturer): Intel, Samsung design & manufacture.
Key Trends
- AI & HPC (High-Performance Computing): NVIDIA, AMD, and Google are investing heavily in AI accelerators.
- Automotive Chips: As cars become more electric/autonomous, demand for power semiconductors (SiC, GaN) is rising.
- Geopolitics & Supply Chain Risks: US-China tensions affect supply chains, leading to reshoring efforts (e.g., CHIPS Act in the US).
- Moore’s Law Slowdown: As transistors approach atomic limits, alternative approaches like chiplets, 3D stacking, and photonic computing are emerging.
4. How to Keep Up?
