Lithography Machine Embargo? No, I'll Make It Myself!

Lithography machines are embargoed by free countries! The chip production line that semiconductor practitioner Zhang Guang worked so hard to build failed to succeed! After being furious, Zhang Guang traveled back to thirty years ago, when telecommunications and semiconductors were just emerging. The time was just right! In the previous life, Long Guo was choked by a photolithography machine. But Zhang Guang discovered that he could actually analyze those neck-stuck techniques! Power module, made by me! Switch, made by me! Program-controlled machines, made by me! 6G, made by me! I make the chip! I can also build a photolithography machine! Many years later, Longguo's 3nm lithography machine was officially put into production, shocking the world. Great Powers: "Oh my god, my neck is a little tight!" Windmill Country: "Dragon Country, you liar, when did you make this big move?!" Free Country: "What, we haven't even prototyped 5nm, yet you put 3nm into production? Should I ban you now, or should you ban me?!" Wan Chai: "Dad, I miss you!" Long Guo: Today, you ignore me; tomorrow, you won't be able to reach me!
