India’s GaN Breakthrough Could Redefine Chip Sovereignty

India’s semiconductor debate is usually dominated by one question: how quickly can the country build fabrication plants?

That question matters, but it is incomplete.

A country does not become technologically sovereign merely because chips are manufactured within its borders. The deeper test is whether it can create semiconductor technologies, own intellectual property, translate laboratory research into commercial products and eventually influence the standards used by global industries.

Gallium Nitride, or GaN, offers India an opportunity to do exactly that.

At the Indian Institute of Science in Bengaluru, years of research into GaN materials and devices have contributed to the creation of AGNIT Semiconductors, an IISc spin off developing indigenous GaN wafers and semiconductor devices.

Its importance goes far beyond one startup.

GaN is emerging as a critical enabling technology for telecommunications, electric mobility, renewable energy systems, defence radar, electronic warfare and high efficiency power electronics.

In other words, the same semiconductor material can influence three of India’s most strategic priorities: next generation communications, energy transition and national security.

For UPSC aspirants, the story is therefore not merely about semiconductors. It connects Science and Technology, industrial policy, strategic autonomy, higher education, defence indigenisation and innovation governance.

Why Gallium Nitride Matters

Most conventional electronic devices are built using silicon.

Silicon transformed modern computing because it is abundant, well understood and supported by a mature manufacturing ecosystem. However, its physical properties create limitations when devices must operate at very high frequencies, voltages or temperatures.

GaN belongs to a class of materials known as wide bandgap semiconductors.

Compared with conventional silicon devices, GaN devices can operate at higher switching frequencies while reducing energy losses. They can also support compact power systems because components such as transformers and capacitors can be made smaller when switching frequencies increase.

These properties make GaN especially attractive for applications where efficiency, speed, size and power density matter.

In telecommunications, GaN based radio frequency devices can support high performance transmitters used in 5G infrastructure and future 6G networks.

In electric mobility, GaN power devices can improve onboard chargers, direct current converters and fast charging systems.

In renewable energy systems, efficient semiconductor switches can reduce conversion losses in solar, storage and power management equipment.

In defence, GaN has strategic value in radar systems, wireless transmitters and electronic warfare equipment.

This explains why GaN cannot be viewed as another specialised semiconductor material. It sits at the intersection of civilian infrastructure and strategic capability.

AGNIT Shows What Technology Transfer Can Achieve

AGNIT Semiconductors emerged from the research ecosystem of IISc’s Centre for Nano Science and Engineering.

The company began operations as an IISc spin off in 2021 and has developed GaN wafers and radio frequency semiconductor products. It has also worked on strategic applications and received support through India’s defence innovation ecosystem.

This progression from academic laboratory to commercial enterprise illustrates a policy challenge India has struggled with for decades.

India has strong scientific institutions.

It has highly trained engineers.

It produces significant academic research.

Yet the journey from research paper to patent, prototype, manufacturing line and commercially scalable product remains difficult.

The semiconductor sector makes this gap particularly visible.

A fabrication subsidy can attract a factory. It cannot automatically produce indigenous semiconductor intellectual property.

That distinction is crucial.

India’s semiconductor strategy has made considerable progress in manufacturing, packaging and assembly. The next stage must give equal importance to technologies originating inside Indian universities and laboratories.

AGNIT demonstrates what this model can look like.

Public research creates technical knowledge. Incubation mechanisms help convert the knowledge into a company. Venture capital provides scaling capital. Government procurement creates an early customer. Industry then carries the technology into commercial markets.

If replicated across institutions, this model could become as important to India’s semiconductor ambitions as any single fabrication plant.

Defence Funding Can Create Civilian Technology Spillovers

The defence dimension of AGNIT is particularly significant.

In 2023, Innovations for Defence Excellence signed a contract with AGNIT for the development of advanced GaN semiconductors. The technology has applications in next generation wireless transmitters used in radar and electronic warfare systems.

This is an example of defence research creating capabilities that can later spill into civilian markets.

Historically, several major technologies have followed a similar pattern internationally. Government funded research creates an initial market because strategic agencies are willing to fund technologies before they become commercially mature.

Once manufacturing scales and costs decline, those technologies can spread into telecommunications, energy, transportation and consumer applications.

India is increasingly attempting the same model.

The broader shift can also be seen in defence technology transfer. PrepAiro’s analysis of DRDO technology transfer to private industry shows how the government is trying to move strategic technologies beyond laboratories and into industrial production.

GaN fits naturally into this transition.

India does not only need missiles, radar systems and communications platforms assembled domestically. It needs control over the semiconductor technologies inside those systems.

That is the deeper meaning of technological sovereignty.

The 6G Opportunity Makes GaN Even More Strategic

India has already declared its intention to play a meaningful role in the development of 6G.

This ambition is different from simply deploying a telecommunications network after standards and technologies have been developed elsewhere.

A country that wants influence in 6G must participate in research, patents, standards, radio systems and semiconductor design.

GaN becomes relevant because future wireless infrastructure will require increasingly sophisticated high frequency radio systems.

India therefore has an opportunity to connect its Bharat 6G ambitions with domestic semiconductor development.

The strategic objective should not merely be to manufacture foreign designed telecom hardware inside India.

It should be to increase the share of Indian intellectual property inside the communications stack.

That transition from implementation to creation is central to technological sovereignty.

For a broader understanding of how new communications technologies fit into the UPSC Science and Technology syllabus, PrepAiro’s Science and Technology guide for UPSC provides useful context on 5G, 6G and emerging technologies.

GaN Versus Silicon Carbide Is Not a Simple Competition

India’s electric vehicle transition adds another dimension to the GaN story.

The two most important wide bandgap semiconductor materials in power electronics are GaN and Silicon Carbide, or SiC.

They are sometimes discussed as if one technology will replace the other. In practice, their strengths differ.

SiC is particularly attractive for high voltage and high temperature applications. This makes it well suited to traction inverters in electric vehicles, particularly systems operating around 800 volts.

GaN excels where very high switching frequency and compact size are important. It can therefore be particularly useful in onboard chargers and direct current conversion systems.

India should therefore avoid treating the choice as GaN versus SiC in absolute terms.

A resilient semiconductor ecosystem requires capabilities in both.

This is especially important because the EV supply chain is already shaped by strategic dependencies.

PrepAiro’s analysis of India’s EV mineral dependence shows how electric mobility can create new forms of import vulnerability even as it reduces dependence on petroleum.

The same lesson applies to power electronics.

An electric vehicle assembled in India cannot be considered fully technologically secure if critical semiconductor components continue to depend on external suppliers.

Semicon 2.0 Must Move Beyond Factories

India’s semiconductor policy is now entering its second phase.

The broader direction of Semicon 2.0 is increasingly focused on expanding India’s capabilities across semiconductor design, manufacturing equipment, materials, packaging, research and workforce development.

That evolution is important.

The first phase of India’s semiconductor mission was necessary because the country needed fabrication investment, packaging capacity and supply chain infrastructure.

But industrial capacity alone does not guarantee technological leadership.

As discussed in PrepAiro’s analysis of Semicon 2.0 and semiconductor sovereignty, the real objective should be control over a larger share of the semiconductor value chain.

GaN offers a useful test.

If Indian researchers create a new semiconductor technology but domestic firms cannot commercialise it, India remains dependent.

If the technology reaches the market but manufacturing moves abroad, part of the strategic advantage is lost.

If India can combine domestic research, intellectual property, device design, wafer production, packaging and commercial deployment, the country moves significantly closer to genuine semiconductor sovereignty.

Deep Tech Capital Is Beginning to Catch Up

Technology transfer requires money as much as research.

Deep technology companies often require years of development before they generate substantial commercial revenue. Semiconductor startups face particularly difficult conditions because fabrication, testing, reliability validation and specialised equipment require large amounts of capital.

Traditional venture capital models may hesitate to support such companies because returns can take longer than in software businesses.

That landscape is slowly changing.

The India Deep Tech Alliance reported that its members invested nearly ₹2,170 crore across 56 deep technology companies during its first year, covering areas including artificial intelligence, quantum technologies, robotics, space, energy and biotechnology.

This matters because India’s ambition to become a technology creator cannot depend entirely on government grants.

Public funding can help research begin.

Private capital is necessary for technologies to scale.

Government procurement can then reduce early market risk by becoming a credible first customer for strategic technologies.

India therefore needs an innovation system in which research institutions, startups, investors, government agencies and large manufacturers operate as connected parts of the same ecosystem.

Universities Could Become India’s Most Important Chip Incubators

The AGNIT story raises a broader governance question.

What is the role of India’s universities in industrial policy?

For years, universities were viewed primarily as institutions for education and academic research. In advanced technology economies, they increasingly function as engines of company creation.

University laboratories can generate intellectual property that is too early for established companies but valuable enough to create new firms.

Successful technology ecosystems therefore need strong mechanisms for patents, licensing, incubation, faculty entrepreneurship and access to early stage capital.

IISc has demonstrated how research infrastructure and incubation can produce commercially relevant deep technology startups.

India now needs similar pipelines across IITs, research laboratories and major universities.

The challenge is not a shortage of scientific talent.

It is the institutional gap between discovery and deployment.

From Technology Consumer to Technology Creator

For decades, India became highly capable at adopting and scaling technologies developed elsewhere.

That model produced major achievements in software services, telecommunications and digital infrastructure.

But strategic technologies demand something more.

In semiconductors, defence electronics, artificial intelligence, quantum technology and advanced communications, dependency on foreign intellectual property can become an economic and security vulnerability.

GaN demonstrates how that trajectory can change.

An Indian research laboratory develops advanced semiconductor knowledge.

Researchers convert the technology into a startup.

Government defence programmes create early demand.

Private investors provide growth capital.

The technology expands into civilian sectors such as telecommunications, electric mobility and energy systems.

That is the innovation cycle India needs to reproduce.

The ultimate goal of semiconductor policy should therefore not be measured only by the number of factories built or investment announcements made.

A more important measure is how many globally competitive technologies originate in India.

If companies such as AGNIT can move from academic research to commercial scale, India’s semiconductor strategy begins to change character.

It stops being only a strategy for reducing imports.

It becomes a strategy for creating technology.

For UPSC, that is the central takeaway.

India’s semiconductor challenge is not simply to manufacture the technologies of the present.

It is to develop the institutional system capable of creating the technologies of the future.
