Ajinomoto: A Strategic Link in the Global AI Race

Ajinomoto, a Japanese company traditionally known for its "umami" flavor and MSG, has become a strategic linchpin in the global race for artificial intelligence dominance through a specialized product: Ajinomoto Build-up Film (ABF).

This ultra-thin insulating film, developed in the late 1990s, plays a crucial role as the "backbone" for semiconductor substrates. Measuring about one-eighth the thickness of a human hair, ABF enables the creation of layers that connect and transmit thousands of signals between chips and devices. Its development stemmed from Ajinomoto's "AminoScience" expertise, with engineers discovering that byproducts from fermenting glutamate for MSG possessed ideal insulating and heat-conductive properties, leading to ABF's creation.

Shigeo Nakamura, the current Chairman and CEO of Ajinomoto Group, led the ABF development project. The material became an industry standard in 1999 when Intel adopted it into its manufacturing processes. ABF's unique molecular structure allows it to remain stable at high temperatures, facilitating the integration of billions of transistors into compact spaces. This innovation transformed Ajinomoto from an unconventional player into a dominant force in semiconductor materials.

Currently, Ajinomoto holds over 95% of the global market share for ABF insulating films. Its market leadership is attributed to a proprietary ecosystem built over two decades, comprising three key barriers: deep expertise in amino acid molecular processing for absolute material stability; exclusive production lines co-developed with machinery manufacturers; and established trust through rigorous U.S., European, and Japanese industry standards. This strategic positioning is further solidified by the current AI boom, which has dramatically increased demand for chips and consequently for essential materials like ABF, with supply-demand gaps projected to widen until 2028.
