The Evolution of Sustainability Research in the Semiconductor Industry: Trends, Knowledge Structures, and Future Research Directions
This bibliometric study analyzes 734 Scopus-indexed publications from 2000 to 2026 to map the evolution, key themes, and knowledge structures of sustainability research in the semiconductor industry, identifying major contributors, core topics like recycling and environmental management, and promising future directions such as the circular economy and renewable energy.

Imagine the semiconductor industry as the bustling, high-speed engine room of our modern world. It's the place where the tiny chips that power your phone, your car, and even the internet are born. But here's the catch: building these microscopic marvels is like running a giant, super-advanced factory that guzzles energy, drinks oceans of water, and spews out toxic fumes. For a long time, the focus was just on making the chips faster and cheaper. But now, the world is asking, "What about the planet?"
This paper is like a massive time-traveling detective story. The authors, Abdullah and Aliza, decided to look back at 734 scientific papers published between 2000 and 2026 to see how researchers are trying to fix the semiconductor industry's environmental mess. They didn't just read the papers; they used special digital tools (Biblioshiny and VOSviewer) to map out the connections, like drawing a giant treasure map of ideas.
The Big Discovery: A Growing Crowd
The first thing the map revealed is that the crowd is getting huge. Since 2018, interest in making semiconductors "green" has exploded, growing at a rate of 14.72% every year. It's as if a quiet library suddenly turned into a roaring stadium. The paper suggests that China, India, and the United States are the biggest players in this game, with China leading the pack in both the number of papers written and the total number of times those papers are cited by others.
The Map of Ideas: What Are They Talking About?
When the authors zoomed in on the keywords, they found three main "neighborhoods" where the action is happening:
- The "Clean Factory" District: This is all about making the manufacturing process itself less dirty. The map shows a heavy focus on "sustainable manufacturing," "decarbonization" (stopping carbon emissions), and "energy efficiency." It's like trying to figure out how to bake a cake without using any electricity or creating smoke.
- The "Recycle Everything" Zone: This neighborhood is buzzing with ideas about the "circular economy." Instead of throwing old chips away, researchers are looking at how to recycle them, recover materials, and manage electronic waste. The paper suggests that turning waste into treasure is a massive trend, with keywords like "recycling," "e-waste," and "resource efficiency" popping up everywhere.
- The "High-Tech Magic" Lab: This area is where science gets really cool. The map highlights research into using semiconductor materials for environmental cleanup, like "photocatalysis" (using light to clean things) and "hydrogen production." It's as if the chips themselves are being retrained to be superheroes that fight pollution.
The Social Scene: Who Is Working Together?
The authors also looked at who is talking to whom. They found that while there are many smart people working on this, they aren't all holding hands yet. The network of countries and universities is a bit "fragmented," meaning there are many small groups working in their own corners rather than one giant, unified team. The paper suggests that while countries like China, the US, and India are doing a lot of work, they need to collaborate more across borders to really solve the problem.
What the Paper Says "No" To
It's important to note what this map doesn't show. The authors explicitly ruled out looking at papers that weren't in English or weren't in the Scopus database. This means their map might be missing some hidden gems published in other languages or other databases. Also, the paper doesn't claim that the industry has already solved its pollution problems. In fact, it points out that the effect of these green practices on how well companies make money is still "unclear." They are still figuring out if being green actually helps the bottom line.
The Future: Where Are We Heading?
Looking at the trends from 2008 to 2026, the paper suggests a clear shift. We used to talk about "strategic planning" and "customer satisfaction," but now the conversation has moved to "circular economy," "risk assessment," and "net-zero manufacturing."
The authors suggest that the future of this field lies in a few exciting directions:
- Closing the Loop: We need more research on how to create a "closed-loop" system where nothing is wasted.
- AI and Big Data: They suggest that artificial intelligence could be the key to monitoring and optimizing energy use in these factories.
- Global Teamwork: The paper emphasizes that because the semiconductor industry is global, the solution must be too. We need more international partnerships.
The Bottom Line
This paper doesn't claim to have the final answer. Instead, it acts as a compass. It tells us that the semiconductor industry is waking up to its environmental impact, and a massive amount of research is now dedicated to fixing it. The path forward involves recycling, clean energy, and better teamwork, but the journey is just beginning. The map is drawn, the treasure is hinted at, but the real work of digging is still ahead.
