Introduction
Imagine a world where cars stop rolling off assembly lines, smartphones disappear from store shelves, defence systems face production delays, and artificial intelligence development slows dramatically—all because of a tiny electronic component measuring just a few millimetres. This was not a hypothetical scenario; it was the reality during the global semiconductor shortage of 2020–22.
Semiconductors have emerged as the “new oil” of the digital economy. Just as crude oil powered the industrial revolution of the twentieth century, semiconductors are driving the technological revolution of the twenty-first century. Every smartphone, laptop, satellite, electric vehicle, fighter aircraft, medical device, communication network, and artificial intelligence system depends on semiconductor chips.
For India, semiconductors represent much more than an industrial opportunity. They are central to economic growth, technological sovereignty, national security, supply-chain resilience, and strategic autonomy. Recognising this, the Government of India launched the India Semiconductor Mission (ISM) in 2021 as a flagship initiative to establish a globally competitive semiconductor and display manufacturing ecosystem.
The mission aligns with broader national initiatives such as Make in India, Digital India, Atmanirbhar Bharat, and the ambition to position India as a global electronics manufacturing hub.
What is a Semiconductor?
A semiconductor is a material whose electrical conductivity lies between that of a conductor (such as copper) and an insulator (such as rubber). Its conductivity can be precisely controlled, making it ideal for manufacturing electronic devices.
The most commonly used semiconductor material is:
- Silicon
- Germanium
- Gallium Arsenide
- Silicon Carbide
- Gallium Nitride
Among these, silicon accounts for nearly 95% of semiconductor production worldwide because of its abundance, stability, and favourable electrical properties.
Why are Semiconductors Called the “Brain” of Electronics?
Every electronic device performs three essential functions:
- Receiving information
- Processing information
- Producing an output
Semiconductor chips perform the processing function. They act as the brain that controls and coordinates all electronic operations.
Examples include:
| Device | Role of Semiconductor |
|---|---|
| Smartphone | Runs applications and communication systems |
| Laptop | Executes computing operations |
| Electric Vehicle | Controls battery management and motor systems |
| Missile | Navigation and guidance |
| Satellite | Signal processing |
| Medical Equipment | Diagnostic imaging and monitoring |
| Artificial Intelligence | High-speed computation |
Understanding the Semiconductor Ecosystem
The semiconductor industry is one of the most sophisticated manufacturing ecosystems in the world.
Research │ ▼Chip Design │ ▼Wafer Fabrication │ ▼Testing │ ▼Packaging │ ▼Electronics Manufacturing │ ▼Consumers
Each stage requires different technologies, investments, and expertise.
Chip Design
This is where engineers design integrated circuits using Electronic Design Automation (EDA) software.
India has already established itself as a global leader in chip design.
More than 20% of the world’s semiconductor design engineers are based in India, with global companies operating large design centres in Bengaluru, Hyderabad, Noida, Chennai, and Pune.
Wafer Fabrication (Fab)
This is the most capital-intensive stage.
A fabrication plant manufactures semiconductor wafers using highly sophisticated equipment.
Typical investment:
US$10–20 billion
Time required:
3–5 years
Extremely clean environments are maintained, often cleaner than hospital operating theatres, because even microscopic dust particles can damage chips.
Assembly, Testing, Marking and Packaging (ATMP)
After fabrication, chips are:
- Cut
- Connected
- Packaged
- Tested
- Certified
India is rapidly expanding capabilities in this segment because investment requirements are lower compared to fabrication plants.
Why are Semiconductors Strategically Important?
Semiconductors influence nearly every major sector of the modern economy.
Economic Importance

Why Did the World Suddenly Start Talking About Chips?
The global semiconductor shortage after COVID-19 highlighted the fragility of concentrated supply chains.
Major causes included:
- Pandemic-induced factory shutdowns
- Surge in demand for laptops and electronics
- Logistics disruptions
- Geopolitical tensions
- Limited manufacturing capacity
The crisis affected industries ranging from automobiles to consumer electronics, leading many countries to prioritise domestic semiconductor manufacturing.
Global Semiconductor Landscape
The global semiconductor industry is geographically concentrated.
