Engineers in California have made an important advance in a technique that could help chipmakers create denser and cheaper integrated circuits. It might also extend the life of the traditional lithography process. With a method called directed self-assembly, the engineers were able to pattern contact holes for transistors in memory and logic 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.
