Most of the hand-wringing over the fate of Moore’s Law focuses on the ever-shrinking silicon transistor. But increasingly researchers are concerned with another critical part of the infrastructure: the copper wires that connect individual transistors to form complex circuits.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
