TSMC and Samsung are both making significant progress toward 2-nanometer and sub-2-nanometer process node production, with commercial availability of the most advanced chips expected in 2027. The transition to smaller nodes is becoming increasingly difficult as quantum mechanical effects at sub-3-nanometer scales create new engineering challenges requiring novel materials, lithography techniques, and transistor architectures.
Beyond shrinking transistors, chipmakers are pursuing three-dimensional stacking, heterogeneous integration of specialized processing units, and photonic interconnects that use light rather than electrical signals for chip-to-chip communication. These architectural approaches offer substantial performance improvements even when transistor scaling reaches its practical limits, suggesting that computing performance gains will continue even as traditional Moore's Law progress slows.
