There are few easy ways to get across the incredible complexity required to build a modern computer chip: this photograph is one of them

Intel's first High NA EUV tool set up.

Chipmaking is tough. Like really tough. Just how tough? An engineer could spend many hours talking about the intricacies of just a single step in the lithographic or packaging process and you'd come away wiser but moderately terrified about the scale of the accomplishments required to create any and all computer chips. But a photograph speaks a thousand words, and these photos of Intel's new lithographic 'High NA EUV' machines make it quite clear how incredibly complex this whole chipmaking biz is.
