Complementary Metal-Oxide-Semiconductor (CMOS) uses pairs of P-type and N-type MOSFETs. This design is the backbone of microprocessors because it consumes almost no power when the circuit is static. Switching Speed and Efficiency

: Adding small amounts of impurities (like phosphorus or boron) creates N-type (excess electrons) or P-type (excess "holes") materials.
