Japan’s industrial competitiveness is greatly affected by cutting-edge semiconductors. It can be said that steady progress toward domestic production of such chips has been demonstrated, as a prototype has been successfully made.

It is hoped that efforts to advance this technology further will be made and that progress will lead to mass production.

Last month, Rapidus Corp., which aims to produce cutting-edge chips domestically, unveiled a prototype of its 2-nanometer semiconductors. One nanometer is one-billionth of a meter. The company said it confirmed that a key component controlling electrical signals functioned properly.

The smaller the nanometer number, the higher the semiconductor’s processing capabilities. As Japanese chipmakers have only achieved production of 40-nanometer semiconductors........
