  • This year, it'll start building chips with a 7-nanometer (7nm) process employing extreme ultraviolet (EUV) lithography. EUV permits smaller features to be etched onto the silicon wafers that are the substrate for chip features.
  • Next, a 5nm process will shrink electronics while lowering power consumption, a key advantage for mobile devices that live on battery power.
  • A 4nm process will shrink electronics another notch and boost performance, Samsung said. It'll be the last chipmaking generation to use a transistor technology called FinFET. The transistor component that controls whether current flows through that channel, called the gate, is in effect draped across the fin.
  • Last comes a 3nm process technology called gate all around, or GAA. It replaces the fin with an electrical channel that looks more like wires, and the gate surrounds it completely instead of being draped across the top.
