The Tata-ASML Dholera project is a planned $11 billion semiconductor manufacturing facility in Gujarat that aims to strengthen India's domestic chip production and support the country's growing electronics industry.
But what exactly is ASML, and why is its technology considered critical for semiconductor manufacturing worldwide? As Tata Electronics advances its semiconductor facility in Dholera, understanding the role of lithography systems, chip fabrication, and advanced manufacturing technology has become increasingly important.
This article explains the technology behind the project and why it matters for India's semiconductor ambitions.
What Is ASML and Why Is It Important?
ASML is a Netherlands-based technology company that develops advanced lithography systems used by semiconductor manufacturers worldwide.
Its machines function like extremely precise nanoscale printers. These systems transfer circuit patterns onto silicon wafers, allowing billions of microscopic transistors to be created on a single chip.
Without lithography technology, modern semiconductor manufacturing would not be possible.
Today, ASML equipment is used across the global semiconductor industry to produce chips used in:
-
Smartphones
-
Computers
-
Automotive electronics
-
Telecommunications equipment
-
Artificial intelligence systems
-
Industrial automation devices
-
Consumer electronics
How Photolithography Works
Photolithography is one of the most important stages of semiconductor manufacturing. The process involves transferring circuit designs onto silicon wafers layer by layer.
Step 1: Wafer Preparation and Photoresist Coating
The process begins with a polished silicon wafer.
Manufacturers deposit thin layers of materials such as conductors, insulators, or semiconductors onto the wafer depending on the manufacturing stage.
The wafer is then coated with a light-sensitive material called photoresist, which allows circuit patterns to be recorded during exposure.
Step 2: Computational Lithography and Pattern Optimization
Before exposure begins, sophisticated software analyzes and optimizes the circuit design.
Advanced algorithms intentionally modify mask patterns to compensate for optical distortions and manufacturing challenges that occur at nanometer-scale dimensions.
This helps improve pattern accuracy and manufacturing yields.
Step 3: Exposure and Pattern Transfer
A photomask (also called a reticle) containing the circuit blueprint is loaded into the lithography system.
The machine generates high-energy light and projects the circuit pattern onto the wafer.
For advanced chip manufacturing, Extreme Ultraviolet (EUV) systems create light using powerful lasers that strike microscopic droplets of molten tin thousands of times every second.
Ultra-precise mirrors then shrink and focus the pattern before transferring it onto the photoresist-coated wafer.
Throughout the process, the machine continuously aligns the wafer and mask with extraordinary precision to ensure accurate layer placement.
Step 4: Development and Etching
After exposure, the wafer undergoes chemical development.
The exposed portions of the photoresist are removed, revealing the circuit pattern.
Manufacturers then etch the exposed areas to create microscopic semiconductor structures.
This process is repeated dozens or even hundreds of times until the complete integrated circuit is formed.

The project forms part of India's broader effort to strengthen domestic semiconductor manufacturing capabilities and reduce dependence on imported chips.
Key Reported Details of the Project
The facility is expected to focus primarily on mature semiconductor technologies ranging from approximately 28nm to 110nm, which remain widely used across numerous industries.
DUV vs EUV Lithography
ASML manufactures multiple categories of lithography systems.
DUV systems are commonly used for large-scale commercial manufacturing and are expected to play an important role in mature-node semiconductor production.
EUV systems are among the most advanced manufacturing machines in existence and are used to produce cutting-edge chips containing billions of transistors.
Industry estimates suggest that advanced EUV systems can cost hundreds of millions of dollars per machine due to their engineering complexity.
Workforce and Employment Impact
Semiconductor manufacturing facilities require highly skilled teams working continuously to support production operations.
Industry reports suggest that advanced lithography systems may require support from multiple specialists including engineers, operators, and maintenance teams.
Key Roles in Semiconductor Manufacturing
Because semiconductor fabrication plants operate 24 hours a day, staffing is typically organized across multiple rotating shifts.
Large semiconductor projects also create employment opportunities across engineering, construction, logistics, utilities, technical services, and support industries.
Publicly reported estimates suggest that the broader ecosystem associated with the Dholera semiconductor project could support thousands of direct and indirect jobs over time.
Why Dholera Was Chosen
Semiconductor manufacturing requires extensive infrastructure support.
Key requirements include:
-
Reliable electricity supply
