IBIDEN CO., LTD.

A former hydroelectric utility from rural Gifu that became the leading supplier of the IC package substrates carrying the world's AI processors.

IBIDEN CO., LTD. headquarters

Business Description

Ibiden's electronics segment makes package substrates — the multilayer boards that connect a semiconductor die to the circuit board beneath it. It is the principal supplier for Intel's server processors and holds a leading position in the FC-BGA substrates required by AI accelerators, a bottleneck component whose lead times and capacity have constrained the industry. A separate ceramics segment makes diesel particulate filters and catalyst carriers for the auto industry.

Substrate demand for AI has driven a heavy capital-spending programme, including the new Ono plant in Gifu, which makes the company's earnings unusually sensitive to how quickly those investments fill. Founded in 1912 as Ibigawa Electric Power, a hydroelectric operator on the Ibi River — the source of the name — it moved into ceramics and then electronics as the utility business was nationalised.
