The metal has done sterling service for 20 years but the time is approaching to find a replacement for copper as problems with parasitics continue to build up, work presented at last month’s IEDM shows. But it's not an obvious switch.
Work by the University of Toronto and Arm presented at IEDM indicates plasmonics could be a viable contender for high-speed chip-chip communications.
Work presented at IEDM 2020 shows taking advantage of the IC backside for power and ground for the additional area can deliver further benefits for IR drop and security.
At IEDM this year, Macronix showed how a 3D architecture may bring back NOR flash, which stopped scaling a decade ago.
Imec's senior vice president of CMOS outlined future directions for the technology over the coming decade.
This year's IEDM will feature papers that exploit stacked nanoribbons to reduce CMOS footprint, graphene interconnects that support easier integration, and the variability prospects of 2D semiconductors.
The organizers of the 66th annual IEDM have decided to hold the December conference virtually.
The IEEE plans to stage the 66th International Electron Device Meeting as a physical event in mid-December.
