I.B.M. will soon be announcing a new breakthrough in its chip-making capabilities. The new technique can increase chip speed by as much as 35% with an additional overall 15% reduction in energy consumption.

I.B.M. to Announce an Advance in Making Chips Faster and More Energy-Efficient

SAN FRANCISCO, May 2 — Scientists at I.B.M. have designed a new material that could increase the speed of semiconductors and reduce their energy consumption.

The advance, to be announced Thursday, involves a manufacturing process that uses heat to create trillions of atomic-scale holes in a thin layer of material deposited on top of the conducting wires at different stages of chip making. The material is then extracted through the holes, leaving insulating vacuum channels around the miles of ultrathin wires that make up a modern microchip.
