What Is a GaN Chip? Why India Is Betting Big on Gallium Nitride Technology

India is one that is at the brink of a big technological change. Decades ago, the nation had become so reliant on imported semiconductor chips that drive smart phones to missiles. The new generation of materials and a new national ambition have taken the place of that dependency. The key component in this change is the GaN chip, a chip that has been developed based on Gallium Nitride.

With the world being facing semiconductor shortages that made it clear that too much reliance on the foreign suppliers was a risk, India started reconsidering its semiconductor policy. Rather than just doing what was done before (silicon-based), policymakers, researchers, and other independent stakeholders began to place bets on next generation chips. Gallium Nitride or GaN soon became a powerful competitor.

It is not a mere narrative on technology. It is a national security story, electric mobility story, 5G network story and a story of India having a role in the global supply chain of technology.

Fundamentals of a GaN chip and what that is

In order to appreciate the importance of GaN chips, it is best to begin with the basics.

A GaN chip is a semiconductor chip that is fabricated out of Gallium Nitride, which is a mixture of gallium and nitrogen. The GaN chips are also built to operate on higher voltages, higher temperature and higher switching speeds as opposed to the traditional silicon chips.

In simple terms:

• Silicon chips are dependable and inexpensive.
• GaN chip is also faster, smaller and more power efficient.

This is the distinction that renders the technology of GaN suitable to the current application systems where efficiency and compactness are essential.

What is so special about Gallium Nitride?

1. Being able to operate high power Wide bandgap material.
2. Reduced energy loss, i.e. heat production.
3. Increased speed of electron movement, which allows high frequency use.

Due to such characteristics, GaN power semiconductors are rapidly replacing silicon in new-generation systems.

Short History of Gallium Nitrate Technology

Gallium Nitride is not new. It has been researched since 1960s. Nevertheless, it has always been challenging and costly to produce large quantities.

The first significant innovation took place in the 1990s, with the development of blue LEDs which became the subject of a Nobel Prize. Such success demonstrated to the world that GaN can be commercially viable.

GaN was experimented in the 2000s in defence and telecom applications in radar systems and satellite communication. During the past ten years manufacturing methods were enhanced allowing the entry of GaN into consumer electronics.

Today, GaN chips power:

• Fast chargers
• Data centres
• Electric vehicles
• 5G base stations

India is a latecomer to the journey compared to some of the world such as the US and Japan, but it is doing so at a time when the world is on a growth spurt in its demand.

GaN vs Silicon: The Change Is occurring Why

Silicon has dominated the semiconductor business of more than 5 decades. So why change now?

The solution is in restrictions.

With the reduction of the size of the devices and the increase in their power, silicon cannot cope with heat and energy loss. GaN offers a way forward.

The main dissimilarities of GaN and silicon.

• Power consumption: GaN chips consume less power.
• Size: GaN parts may be significantly small.
• Speed: A high switching rate allows high frequency use.
• Sturdiness: Ideal high temperature working.

In the business sense, this implies:

1. Bigger smaller chargers of the same power output.
2. EVs that have a higher range and quicker charge.
3. Smaller-energy consuming 5G networks.

That is the reason why most analysts think the GaN technology is not taking the place of silicon everywhere, but it is dominating the high-performance segments.

The importance of GaN Chips to India in Particular

Interest in GaN is not in vain by India. It is in complete accord with the strategic requirements of the country.

India is:

• It is among the highest energy consumers.
• Quick shift towards electric cars.
• Deployment of 5G and 6G networks.
• Increasing the defence and space potential.

The applications of the GaN chip are helpful in each of the sectors.

The essential reasons why India is gambling on GaN technology.

1. Reduced import dependence
2. Strategic defence superiority.
3. Energy efficiency goals
4. Conformance to Make in India semiconductor vision.

The need to have sophisticated semiconductors in order to have technological sovereignty has been repeatedly pointed out by government think tanks such as the NITI Aayog.

India Semiconductor Mission and the GaN Opportunity

The turning point was the India Semiconductor Mission. It was an indication that it is no longer an industry problem but a national issue that semiconductors are.

The government intends to under this mission to:

• Develop national production of fabrics.
• Stimulate work on the compound semiconductors.
• Win over international semiconductor companies.

Gallium Nitride is appropriate as it:

1. India is able to outpace the obsolete technologies.
2. GaN fabs are less specialised and smaller.
3. Defence and telecom are in high demand.

As the government statistics released in the policy briefings indicate, the demand of the electronics is projected to reach USD 300 billion in the nearest years in India. In the absence of domestic chips, this demand would be translated to huge imports.
