The logical next step from there will be to starting building up – moving from chips that are almost completely 2D to fully 3D chips. When that happens, we’ll have to figure out a way to cool them. Unlike with a 2D chip, you can’t just stick a big heatsink and fan on top because it would only cool one surface, leaving the bulk of the chip to overheat. What you need is a network of cooling pipes distributed throughout the chip, almost like a biological system.
