Intel and two other major semiconductor makers bought stakes in ASML in 2012, in part to help fund development of ASML's newest generation of lithography systems, which perform a critical step in the chipmaking process. The chipmakers have been gradually selling down their stakes in ASML since.

In December 2017, the AFM said Intel's stake had fallen below a 5 percent reporting threshold.
