Investing without understanding value is merely following the trend and will ultimately lead to confusion! (For knowledge sharing only, not investment advice)
What does chip manufacturing rely on? It relies on equipment. Lithography machines are responsible for "drawing", while etching machines are responsible for "carving". Each process determines the performance and yield of the chip. Domestic semiconductor equipment is entering a critical period; who will break through first, the "Big Three in Lithography" or the "Four Little Dragons in Etching"?
