At 0.8 nanometers, carbon film may replace two layers in future chip wiring

As transistors inside microchips continue to shrink, the metal wiring that connects them is becoming a growing obstacle to faster, more energy-efficient chips. Narrower wires have greater electrical resistance, while smaller gaps between them increase interference between adjacent signals. These effects impede data transfer and raise energy consumption
