Copper bottomed move ‘pushes the boundaries’ of on chip interconnect technology

Copper bottomed move ‘pushes the boundaries’ of on chip interconnect technology

In a move which it says 'pushes the boundaries' of interconnect technology, Applied Materials has released the Endura Amber physical vapour deposition system.

Leading edge chips feature complex, multilevel networks with more than 60 miles of copper wiring and as many as 10billion vertical connections between layers. In the future, interconnect structures will be narrower and deeper, making it more difficult for conventional technologies to fill the structure completely and reliably with copper. Applied's Amber copper reflow technology uses capillary action to draw deposited copper into the smallest features.
"The Endura Amber system delivers a breakthrough solution for scaling interconnects beyond the 20nm node, while maintaining good production yields," said Sundar Ramamurthy, general manager of Applied's Metal Deposition Products business unit.
