Fun facts about AMKOR TECHNOLOGY, INC.

1
The Basics
U.S. semiconductor services company · mid-cap · listed on Nasdaq · headquartered in Arizona.
2
The Numbers
Annual revenue in the range of $6–7 billion, with dozens of manufacturing facilities spread across Asia and beyond — because this business lives where the chips are actually made.
3
The History
Founded in 1968 in South Korea, it was built by a Korean-American entrepreneur and eventually moved its corporate home to the United States while keeping most of its factories in Asia.
4
The Secret
It doesn't design or fab chips — it does the packaging and testing that happens after fabrication, the unglamorous step that turns a wafer into a working part you can actually solder down.
5
The Lore
It is one of the world's largest outsourced semiconductor assembly and test (OSAT) providers, serving chipmakers who'd rather not run their own back-end factories.
6
