The article has Jai Hind spirit down to a tee. Nevermind if 2nm will even be able to be mass produced by 2025. Nevermind that currently, the best Japanese semiconductor industry could do is 65nm. Nevermind Japan literally have no market for such product. Nevermind US will never let Japan have such advanced technology, and nevermind US have already destroyed Japan's semiconductor industry in the past.
Japan will have 2nm nodes by 2025, guys! Banzzaaaaiiiii!!!!
Remember that TSMC is only able to produce the most sophisticated IC chips in the world because it is provided with the tools and materials to do so, including EUV lithography machines, vapour deposition machines, and photoresists that are mostly imported. TSMC is a Taiwanese company and Taiwan is a defacto loyal vassal of the United States, so the United States will not object to its allies such as Japan, the Netherlands, any other EU country having their companies provide TSMC with equipment and materials necessary for it to produce such amazing chips. Even Chinese companies supply TSMC with vapour deposition and etching equipment.
An analogy for TSMC is that it is the best chef in the world, capable of cooking any meal very deliciously. But that chef doesn't produce his own ingredients, nor does he make the best cooking knives, pots, and pans that he cooks with. He purchases them from various suppliers.
Remember that Japan is capable of producing to high quality all equipment used in IC chip manufacturing except EUV lithography machines. Gigaphoton is a Japanese company that is capable of producing the power light source to vapourize tin droplets used in ASLM's EUV lithography machines, even though it is not the supplier of that light source. It is very plausible that if Japan committed itself politically it could acquire ASML's machines to produce 7 nm and below IC chips, establishing a company or bestowing one or more existing companies for that purpose. Additionally, Canon does possess nanoimprint lithography technology that can produce at nodes of less than 20 nm.
The main barrier to that, even given such political will, is not Japan's lack of technological capability but whether there is sufficiently a market for a new major Japanese entrant into it. China doesn't have that market barrier, since China is actually presently subject to a defacto partial embargo and has the domestic market to undertake import substitution on a highly dominant scale. China has already committed itself to such gradually heightened import substitution.
