Samsung Plans a "4nm" Process

Samsung has added a so-called "4nm" process to its roadmap:

At the annual Samsung Foundry Forum, Samsung announced its foundry's roadmap for the next few years, which includes an 18nm FD-SOI [(Fully Depleted – Silicon on Insulator)] generation targeting low-cost IoT chips as well as 8nm, 7nm, 6nm, 5nm, and even 4nm process generations.

[...] 7LPP (7nm Low Power Plus): 7LPP will be the first semiconductor process technology to use an EUV lithography solution. 250W of maximum EUV source power, which is the most important milestone for EUV insertion into high volume production, was developed by the collaborative efforts of Samsung and ASML. EUV lithography deployment will break the barriers of Moore's law scaling, paving the way for single nanometer semiconductor technology generations.

[...] The 4LPP process generation will be Samsung's first to use a "Gate All Around FET" (GAAFET) transistor structure, with Samsung's own implementation dubbed "Multi Bridge Channel FET" (MBCFET). The technology uses a "Nanosheet" device to overcome the physical limitations of the FinFET architecture.

But how many transistors per square millimeter is it?

  So you prefer misleading press releases to factual ones? In what way is "break the barriers of Moore's law scaling" a sensible way of saying "continue Moore's Law", not least because it implies that Moore's Law says the exact opposite of what it actually does?

  There have always been barriers to further scaling. Whether they can be overcome or not, or overcome economically, are other concerns.
