Arthur T Knackerbracket has found the following story:

Intel on Thursday announced that it would delay mass production of its 10 nm processors from 2018 to 2019 due to yield issues. The company has claimed to be shipping some of its 10 nm chips in small volumes right now, but due to cost reasons the firm does not intend to initiate their high-volume manufacturing (HVM) at this time. Intel executives also stated that they are confident of their product roadmap and intend to launch Whiskey Lake and Cascade Lake products later this year.

[...] Intel blames a very high transistor density and consequent heavy use of multipatterning for low yields. Brian Krzanich has said that in certain cases the company needs to use quad (4x), penta (5x), or hexa (6x) patterning for select features as they need to expose the wafer up to six times to "draw" one feature. This not only lengthens Intel's manufacturing cycle (which by definition rises costs) and the number of masks it uses, but also has an effect on yields.

Intel's 10 nm fabrication technology relies solely on deep ultraviolet (DUV) lithography with lasers operating on a 193 nm wavelength at this time. The company's 7 nm manufacturing process will use extreme ultraviolet (EUV) lithography with laser wavelength of 13.5 nm for select layers, eliminating use of extreme multipatterning for certain metal layers. As it appears, right now Intel executives do not consider EUV technology ready for prime time in 2019, so the company's engineers have to polish off the last DUV-only process (again) rather than jump straight to 7 nm.

The delay means another generation of "14nm" products:

Intel does not elaborate whether it intends to ship (in volume) its 10 nm CPUs in the first half or the second half of 2019, but only says that the company’s engineers know the source of the yield problems and are working hard to fix them. As a result, it is pretty safe to assume that the actual ramp of Intel’s 10 nm production will begin towards the second half of next year.

In a bid to stay competitive before its 10-nm CPUs ship in the H2 2019 – H1 2020 (production ramp takes time, bigger processors will launch later than smaller parts), Intel plans to release another generation of products made using its 14 nm process tech. This generation of chips includes Whiskey Lake products for client PCs and Cascade Lake for the datacenter, and both are scheduled for release later this year.
