I received the book and immediately opened it to read. The first chapter of the book introduces the high integration of chips. Its integration of large-scale circuits in a small area is really amazing. It is hard to imagine that integrated circuits would develop so rapidly after humans created the first transistor in 1947. The book says that chips are the pinnacle of man-made things, and I deeply agree with this statement. First of all, it feels very difficult to extract high-purity wafers. It is hard to imagine how much energy and effort the R&D personnel have spent to improve the purity. Circuits are constructed in chips with unimaginable precision through various processes. It can be said that chips are the most dazzling achievement in the human technology tree. People living in agricultural societies one or two hundred years ago may not be able to imagine how much convenience chips have brought to people's lives. It has profoundly changed people's lives. It has exerted the powerful force of electromagnetic force, one of the four fundamental forces in the universe. The rapid development of chip technology in less than a hundred years has forced me today to think deeply about what it will be like in the next hundred years. Is it the widespread use of nuclear energy that has given people endless energy, or the rapid development of quantum technology that has realized things that people today cannot even imagine, or the breakthrough in physics that can control the power of fields in the universe? Just like a frog living in a deep well cannot imagine the outside world, we cannot predict the future of history, but for us today, chips are like lightning that breaks through the darkness and illuminates human history.
