Advanced Transistor Tech

The basic MOSFET switch you met earlier in this knowledge base doesn’t stay flat and simple forever — as transistors shrank toward atomic scale, engineers had to reinvent their 3D shape, reinvent the light used to print them, and eventually reinvent the whole idea of “one chip” itself. This section covers the technologies keeping Moore’s Law alive: FinFETs, gate-all-around transistors, EUV lithography, and chiplet-based packaging.
