India's semiconductor sector has reached a pivotal moment with the development of indigenous compound semiconductor chips by a team of dedicated scientists. This breakthrough positions the nation among an elite group of six global leaders in this advanced technology domain. Compound semiconductors, materials like gallium nitride (GaN) and silicon carbide (SiC) that outperform traditional silicon in high-power and high-frequency applications, are crucial for next-generation electronics, defense systems, and renewable energy solutions.
The achievement stems from years of persistent research amid international technology transfer restrictions. When foreign companies declined to share proprietary compound chip know-how, Indian researchers turned inward, leveraging homegrown innovation to bridge the gap. This self-reliant approach aligns with the India Semiconductor Mission (ISM), launched in 2021 with a ₹76,000 crore investment to foster domestic fabrication, design, and assembly capabilities.
Recent reports highlight how this development not only reduces India's import dependence—currently over 95% for advanced chips—but also catapults the country into strategic applications like 5G infrastructure, electric vehicles, and satellite communications. As Union Minister Ashwini Vaishnaw noted in recent addresses, four new semiconductor plants are slated to commence production in 2026, amplifying this momentum.
Understanding Compound Semiconductors: Beyond Silicon Limits 🚀
Compound semiconductors differ fundamentally from silicon-based chips. While silicon (Si) dominates consumer electronics due to its abundance and cost-effectiveness, compound variants combine elements like gallium, arsenic, indium, or carbon to achieve superior electron mobility, thermal conductivity, and breakdown voltage. Gallium nitride (GaN), for instance, enables devices that operate at higher voltages and frequencies, ideal for radar systems and fast chargers.
The fabrication process involves metal-organic chemical vapor deposition (MOCVD), where precursors react to form crystalline layers on substrates. Indian scientists mastered this through iterative experimentation at facilities like the Semi-Conductor Laboratory (SCL) in Mohali, overcoming issues like lattice mismatch and defect density that plague epitaxial growth.
Historically, only nations with mature ecosystems—such as the United States, Japan, Germany, South Korea, Taiwan, and China—dominated this space. India's entry disrupts this oligopoly, driven by necessity in defense and space sectors where supply chain vulnerabilities were exposed during global shortages.
The Research Journey: Institutions and Key Players 🔬
At the forefront is the Institute of Nano Science and Technology (INST) Mohali, under the Department of Science and Technology (DST). Collaborative efforts with IITs, IISc Bangalore, and SCL Mohali culminated in prototype chips validated through six shared wafer runs, involving 46 academic institutions and 122 chip designs under the Chips to Startup (C2S) program.
Lead researchers, drawing from publications in journals like IEEE Transactions on Electron Devices, detailed processes for GaN-on-SiC heterostructures. Their work, published recently, demonstrates chips with 10x higher efficiency in power amplification compared to silicon counterparts. This publication marks a milestone, earning citations and sparking international collaborations.
The C2S initiative has trained over 1,000 engineers, developed 140 reusable IP cores, and supported 23 chip design projects via the Design Linked Incentive (DLI) scheme. Academic contributions from IIT Madras' Shakti processor team and IIT Bombay's analog design groups provided foundational expertise.
- SCL Mohali: Executed wafer fabrication for prototypes.
- INST Mohali: Novel material synthesis techniques.
- IISc: Simulation and modeling support.
For aspiring researchers, opportunities abound in higher education research jobs, where such projects bridge academia and industry.
Overcoming Technological Hurdles Step-by-Step
Developing compound chips required navigating epitaxial growth challenges. Step 1: Substrate preparation—using prime-grade SiC wafers imported initially, then scaling to domestic production. Step 2: Nucleation layer deposition to minimize dislocations. Step 3: High-temperature growth of GaN layers under precise ammonia and metal-organic flows.
Defect densities were reduced from 10^9 to 10^7 cm^-2 through buffer layer innovations, as detailed in a 2025 DST report. Purity issues in precursors were addressed via indigenous synthesis, cutting costs by 40%.
Testing involved RF characterization up to 10 GHz, confirming performance metrics rivaling global benchmarks. This resilience echoes India's RISC-V based DHRUV64 processor, a 64-bit indigenously designed chip on 28nm nodes.
