Silicon wafer

As the pace of Moore's Police force advances have slowed, and the benefits of each new node take gotten steadily smaller, we've seen the various foundries adopt different means of dealing with the problem. Intel has pursued traditional scaling, but is spending longer at each node. Just companies like Samsung, GlobalFoundries, and TSMC have defined a system of brusque and long-lived nodes, with different characteristics and their own individual roadmaps for how long each node will concluding.

Unlike TSMC and Samsung, both of which have 10nm products on their roadmaps, GlobalFoundries opted to leap direct for 7nm subsequently licensing 14nm production from Samsung. Information technology was an ambitious move for the foundry, which had problems with its initial roadmap after spinning itself off from AMD and eventually had to drop its own 14nm XM process plans in favor of a Samsung licensing deal. With 7nm, GlobalFoundries is planning to develop its own process applied science and rollout schedule. Nosotros've previously talked about the visitor's plans for a 2H 2018 high volume manufacturing outset, but Anandtech has additional details on how the 7nm rollout will be handled.

In the table above, DUV refers to Deep Ultraviolet lithography, or the current 193nm lithographic systems already in utilize. GlobalFoundries first 7nm try will use conventional lithography, with either 60 percent reduced ability or xl percent improved functioning.

The introduction of EUV into second-generation 7nm isn't actually expected to amend device performance or power consumption. The goal hither is to introduce EUV to reduce reliance on triple and quadruple patterning. Right at present, these techniques are required to use a 193nm excimer laser to compose features at such tiny sizes, merely they drive up mask counts and manufacturing costs. GlobalFoundries does note that the yield improvements expected from using EUV (assuming the technology is ready on-schedule) could permit for superior binning and allow some device enhancements for that reason.

GF-7nm

Finally, there's a third generation of 7nm planned, with improved line border roughness, uniformity, and other refinements that deal with some of the issues that currently plague EUV production. The company isn't characterizing its expected gains from these changes, other than to say that it should be able to offer lower ability and higher performance in third-gen EUV compared with previous products.

Much of this will depend on ASML, a company that makes photolithography systems for semiconductors, being able to evangelize production-set EUV on-schedule — and every bit we've covered before, that'south nevertheless unproven. The visitor has clearly made progress in contempo years, but we're not going to count EUV every bit gear up for volume production until volume parts are actually rolling off foundry lines.

As for GlobalFoundries, if it tin can stick to this three-wave blueprint, it should be well positioned to compete with TSMC and Samsung. Hither'southward hoping for a 3-way race to adjacent-generation foundry nodes rather than the (still positive) two-mode competition we saw at 14nm.
