Atomic layer etching and deposition processes offer atomic scale control through the use of self-limiting reactions.
Bottoms-up ELD of Cobalt Plugs
As reported in more detail at Solid State Technology, during the IEEE IITC now happening in Grenoble, imec and Lam showed a new Electroless Deposition (ELD) cobalt (Co) process that is claimed to provide void-free bottoms-up pre-filling of vias and…
