For decades now, semiconductors have been made using ever-finer wiring, enabling the famous Moore's law, which predicts a doubling of performance every two years or so. But, as transistors have gotten smaller, some chipmakers are struggling to keep up.

Driving the news: The latest shift to 7-nanometer wiring is proving to be the toughest yet. Intel has already admitted challenges and now one of the other industry giants, GlobalFoundries, said Monday it's going to focus on other types of advances rather than moving to 7 nanometers amid the high costs of the new generation.
