Intel Says "7nm" Node Using Extreme Ultraviolet Lithography is on Track

Intel: EUV-Enabled 7nm Process Tech is on Track []

Originally planned to enter mass production in the second half of 2016, Intel's 10nm process technology is still barely used by the company today. Currently the process is used to produce just a handful of CPUs, ahead of an expected ramp to high-volume manufacturing (HVM) only later in 2019. Without a doubt, Intel suffered delays on its 10nm process by several years, significantly impacting the company's product lineup and its business.

Now, as it turns out, Intel's 10nm may be a short-living node as the company's 7nm tech is on-track for introduction in accordance with its original schedule.

For a number of times Intel said that it set too aggressive scaling/transistor density targets for its 10nm fabrication process, which is why its development ran into problems. Intel's 10nm manufacturing tech relies exclusively on deep ultraviolet lithography (DUVL) with lasers operating on a 193 nm wavelength. To enable the fine feature sizes that Intel set out to achieve on 10nm, the process had to make heavy usage of mutli-patterning. According to Intel, a problem of the process was precisely its heavy usage of multipatterning (quad-patterning to be more exact).

By contrast, Intel's 7nm production tech will use extreme ultraviolet lithography (EUVL) with laser wavelength of 13.5 nm for select layers, reducing use of multipatterning for certain metal layers and therefore simplifying production and shortening cycle times. As it appears, the 7nm fabrication process had been in development separately from the 10nm tech and by a different team. As a result, its development is well underway and is projected to enter HVM in accordance with Intel's unannounced roadmap, the company says.

Meanwhile, an unconfirmed leak of AMD's Ryzen 3000 lineup [] shows a 12-core CPU at $300 and a 16-core CPU at $450.
