study semiconductor manufacturing not to build a fab. not to get a job at TSMC. but to witness how far the human mind has gone. photolithography is pure magic disguised as engineering. we’re literally etching patterns smaller than viruses; using light, mirrors, gases, plasma, and math. machines that cost billions; all to place atoms exactly where we want them. a chip isn’t just silicon. it’s the story of precision, obsession, and human imagination pushed to its limit. study how semiconductors are made; because it’s not just technology, it’s a love letter to what humans can do when they decide to understand everything.
