Chips are built through repeated lithography, deposition, and etching in controlled environments. Wafers undergo patterning and layer formation to create transistors, interconnects, and insulators. Doping sets electrical behavior, while diffusion sculpts dopant profiles. Each step is monitored by metrology and inline testing to preserve yield. Packaging then connects die to external circuits. The process balances performance, thermal limits, and defect control, leaving open questions about scaling and reliability as new materials enter the mix.
