When it comes to microchip technology, transistors seem to get all the attention. But did you know that the transistor layer only makes up 10% of a modern logic chip?

The other 90% is made up of interconnect layers – the three-dimensional maze of copper wires that make connections between all those transistors and the outside world. From a volume perspective, that makes the dielectric insulator that supports all that copper the most important material in all of chipmaking!
