BBC NEWS Technology Snowflakes promise faster chips: "Chips could run faster and be more energy efficient thanks to a process from IBM that copies nature's creation of seashells and snowflakes.
The process, called airgap, enables trillions of microscopic vacuum holes to be placed between the copper wire in chips to act as an insulator.
It solves the problem of electrical energy leaking between wires, which creates unwanted heat.
IBM says the chips will run 35% faster and consume 15% less energy. "
