AI Hardware Supply Chain: Focus on Third Derivative Enablers

By PulseAugur Editorial · [7 sources] ·

SemiAnalysis highlights the critical, often overlooked, "third derivative" companies in the semiconductor supply chain that enable advanced AI hardware. These include material suppliers like Ajinomoto, which dominates the ABF film market essential for substrates, and chemical companies such as MEC, holding a near-monopoly on adhesion-promotion chemistry for ABF substrates. The analysis also points to equipment manufacturers like Eternal Precision Mechanics and Taesung, whose tools are crucial for the multi-layer lamination and wet-processing steps in substrate production, with demand scaling directly with substrate complexity and layer count.

    The broader point is that semiconductor research often gets more interesting as you move down the stack. AI accelerators are the first derivative. Memory, networking, power and advanced packaging are the second. But the third derivative is where you find the companies enabling

    Then there is Ajinomoto ($2802.T). Ajinomoto controls roughly 95% of the ABF film market. ABF is the insulating film laminated between the copper layers of an advanced substrate. So while MEC captures the chemistry required to process the substrate, Ajinomoto supplies one of the

    Take ABF substrates, for example. As accelerator packages have grown larger and more complex, substrate capacity has emerged as a key constraint in the supply chain. Substrate demand is increasing along two dimensions: More units and substantially more content per unit.
