What Is Ajinomoto Doing in AI Chips?

Most people know Ajinomoto as the Japanese company behind MSG and food seasonings found in kitchens and restaurants around the world.

What far fewer people realize is that the same company also plays a crucial role in the modern semiconductor industry, particularly in advanced AI chip packaging.

At first, that connection sounds surprising.

But decades ago, an unexpected discovery inside Ajinomoto’s research labs quietly set the company on a path far beyond food products.

Over time, that discovery helped Ajinomoto become an important supplier in the global semiconductor industry. 

Today, its technology supports the packaging of high-performance processors used in artificial intelligence, cloud computing, and modern data centers.

The Surprising Origin of Ajinomoto’s Semiconductor Business

The company’s entry into semiconductor materials happened almost by accident.

In the 1970s, researchers at the company were studying resin compounds and byproducts created during the production of MSG and other food products.

During this research, they discovered that some of these materials could handle heat well and protect delicate electronic components inside chips.

Instead of abandoning the discovery, Ajinomoto spent years improving the technology.

After decades of development, the company created Ajinomoto Build-up Film (ABF), a specialized material used in advanced semiconductor packaging.

At the time, few could have predicted that a food company would become deeply connected to the future of computing and artificial intelligence.

As chips became faster and more powerful, companies also needed better materials to support them. Ajinomoto continued refining ABF as the industry rapidly evolved.

By the late 1990s and early 2000s, ABF had become increasingly important as computer chips became more powerful and advanced.

Why ABF Matters for AI Chips

For years, ABF remained a highly specialized material used quietly within the semiconductor industry.

But the rapid rise of artificial intelligence changed everything.

As companies raced to build more powerful AI systems, demand also surged for high-performance chips capable of handling massive amounts of data. That also increased the need for sophisticated semiconductor packaging materials like ABF.

Modern AI chips, such as NVIDIA’s H100 GPUs, are incredibly complex and contain billions of tiny electronic components. These chips are widely used by global cloud providers and AI companies to train and run advanced AI models.

To operate efficiently, these processors depend on advanced packaging materials that help:

• Support fast communication between different parts of the chip

• Protect sensitive electronic components

• Enable smaller and more powerful chip designs

• Maintain stability under intense workloads

This is why materials like ABF have become increasingly important in the AI era.

Although ABF represents only a small fraction of a GPU’s total cost, it still plays a critical role in enabling advanced AI chip performance.

Ajinomoto’s Dominance in the ABF Market

As demand for AI infrastructure continued rising, Ajinomoto’s importance within the semiconductor supply chain also grew rapidly. 

Today, the company is widely regarded as the dominant supplier of ABF insulating film used in advanced chip packaging.

Industry reports estimate that Ajinomoto controls roughly 95–96% of the global market for high-end ABF materials. This makes Ajinomoto one of the most important companies quietly supporting the AI industry.

Its technology is used not only in advanced AI chips but also in:

• Data center processors

• High-performance computing systems

• Networking equipment

• Advanced server hardware

As AI infrastructure continues expanding worldwide, materials like ABF are becoming more important than ever.

Conclusion

Ajinomoto’s rise from a food seasoning company to a key semiconductor industry supplier shows the value of long-term innovation.

While companies like NVIDIA and TSMC dominate AI headlines, Ajinomoto’s ABF technology quietly supports the advanced packaging behind modern AI chips and data center infrastructure.

Its story shows that key AI infrastructure companies are not always the most visible.

The next time you see Ajinomoto on a food packet, remember that the same company is also helping support the future of artificial intelligence behind the scenes.
